[Q] Is there a faster charging cable out there? - Moto X Q&A

Using the app Ampere which detects charging rates of different USB cables, I found that Motorola USB cables give a consistent 590mA charging rate.
I bought some Anker USB cables which look and feel very durable, and they also give a maximum of 600mA BUT.....it does start to vary and it's not consistent. At times, the rate will go all the way down to 320mA and rise up to 590mA or it'll just decrease to 570mA and again go back up to 590mA or 600mA. It's not as consistent as the Motorola USB cable. As I'm typing this out, it went down to 330mA and now it's just been ranging in the 420-450mA for the past couple of minutes.
So has anyone found any other alternative cables and maybe used the Ampere app to check their charging rate?

Finding faster charging cable is bit difficult. Usually people don't use that app if there phone is charging normally.
If you want to quickly charge your phone, try using Samsung's charger which have a output of 2100 mA

I've never used that app.... Are you 100% sure it reads the input current at the port itself, rather than "surplus" current which is input current less any power the phone is using to operate?
Are you sure that app is 100% accurate?
I use Battery Monitor Widget by 3C and I see current fluctuations all over the place.
The 1st Gen (aka 2013) Moto X ships with a 1.15A (aka 1150mA) charger. I also have an older HTC 1A charger, the wall plug (aka wart) end of an iPad 2.5A charger, as well as my Samsung 1.5A and 2A chargers (for my GS5 and Tab 10.1"), either using the USB cable they came with, or various USB cables from Moto (shipped with several Moto android phones i have), Samsung cables (again from various samsung phones), and generic and other USB cables I have, they ALL charge at the As well as Moto and Verizon Micro USB car chargers.
My X charges at about the same rate, as long as the wall plug of the charger is 1A or higher, so long as I'm not using a "power hungry" app like Google Maps, streaming music across Cellular via Rhapsody, streaming video via Netflix or Comcast apps, etc. It doesn't matter what mix of wall plug and USB cable, or car charger I'm using either.
I also have a 1.5A Blackberry Playbook charger on my desk at the office. It too doesn't charge any slower or faster than 1A chargers.
If I used older Blackberry 750mA and 850mA, I then notice a slower charging rate.

I have the same issue. I have a few different cables, but this cable at monoprice charges stupid fast.

Here's some screenshots. The ~500mA is a random cable. The 750mA is the cable I linked to. This is all on a 1A charger.

Personally I'd check out this product.
http :// www .amazon . com/gp/product/B00QTJZ3D0/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 (Can't post links yet even though I'm being helpful, so just remove spaces.)
I have this one right now and it quickly charges my phone. Two downsides; it'll start doing the "position your phone in a certain way" thing, but it comes with a warranty or you could just buy another one like I did.
Also, the cable is kinda short but an extension cord helps.
Anyways, those are my thoughts, good luck finding one!

I have never seen more faster charger/cable than this one: ebay .com/itm/351145955499.

ok, a few basics and an answer to your question of at the bottom of course
a) you cannot measure the current flow in app in real time really. to accurately measure your current = mAh you need a amperemeter which is looped in between the source and the consumer. you find them on amazon and ebay with ease.
b) you need to measure when your battery is below 90% charge because the charging is managed by software and only when the battery is significantly below 100% it will charge more or less steadily.
c) you have to test with the screen of because different content on your screen is using different amount of power, in general you have to make sure
that as much as you can do that the conditions are the same and that ideally there is some significant workload on the phone, for example if you can trigger media scanner manually that's a great consumer which will use all possible resources from source (charger) and cable. ( cause max throughput)
d) i tested about 30 different cables on wall chargers, on motorbike plug and in my cars and there are huge differences between the cables which of course can be reproduced, thus be measured repeatedly and with regularly same or very similar results. what is astonishing among my cables are several original oem charging cables from the same oems and even between those the differences are up to 100% ( or 50% if you calculate from top )
e) answer to your question, the best cable i have in my collection is: THIS ONE ! only downside, it's a bit rigid to the side because it has a flat form factor.
EDIT: just thought it might be helpful to provide a few numbers: bad cables provide around 500mAh, good cables around 1A(1000 mAh) and the best mentioned up to 1950mAh under identical conditions.

Knock-off Chargers

I am hesitant to buy something like this since I have read that the USB Micro on the NC is non-standard.
http://www.ebay.com/itm/Barnes-and-...?pt=US_Tablet_Accessories&hash=item19c71f2149
You're smart to worry about these. This one is a simple microUSB cable, not the Nook Color compatible cable which has a longer tip. It will still allow you to transfer data and trickle charge but because of the shorter tip it will not allow a quick charge.
The part that is also important is the plug/brick you plug this cable into. You have to make sure it outputs 1.9 amps so that it is capable of quick charging your Nook Color if you have the correct cable to use. Most usb plug/bricks (like the ones for your phones) will only output about a quarter or maybe half of that. Some Apple iPad/iPhone usb plug/bricks will put out more though.
sjmoreno is right, be wary on these. It shows it is shipping from the inside the United States, but that doesn't mean much as they buy these in bulk from China at a lower price and raise it a bit here. I have ordered a few of these micro USB cables from china eBay listings with varying luck. Some will actually fit, and others won't - some charge REALLY slow and I actually had one that melted on me because it was pulling too much current.
Hey,
If you are still under warrantly, you can call B&N or chat with them on the website and get a new cable, adaptor or a power kit with little or no trouble. Just tell them your current one is not working. You can also go to a Barnes and Noble store and speak to one of the nook guys and you can get a free one there too.

Chargers (wall or vehicle) made for Apple products will only charge at the slower rate. The NC looks at the resistance on the USB data lines to see if it should charge at the fast rate. The resistance set on chargers for Apple products is different than for the NC. The only chargers I've come across for the NC that charge at the higher rate are those made by B&N. Other chargers can be modified to work, but that's a different topic.

Wow, you actually sound like you know what you're talking about. (I kid... I kid...)
Here's a photo of my Apple USB plug which I've highlighted puts out 2.1A. I could use this plug with the official B&N Nook Color cable and it will get the quick charge since the extra length of the tip on the B&N NC cable will allow it to reach the 12 pins that are further inside the Nook's outlet. Although I wouldn't do it since it could (maybe, might, don't want to chance it) send too much current to the battery and possibly damage it or over-heat it.
I also have a Motorola usb plug for my Droid X and Atrix phones but that only puts out 850 mA (.85 Amps) which could trickle charge regardless of the cable I use.
Hope this explained it well enough.

right back at ya!
Your Apple unit is rated at 2.1A, but will only 'put out' whatever the NC draws from it, up to a theoretical 2.1A (I never measured over ~1850mA during any of my testing). Have you measured the charge rate on your NC? How? Did you load the battery monitor widget, does it report 'AC Charge' with the Apple charger? Are you using the Nook Tweeks app and forcing the fast charge mode? Just curious.
You made some other comments that are misleading, so I'll say my 'opinion' on those:
You could hook your NC to a 5V, 10,000+Amp power supply and not hurt it. The NC regulates the rate of charge with an on-board charge controller, and even if it didn't, it still wouldn't harm the battery. USB is 5V by specification. Apply 5V to a battery currently holding a charge of less than 5V and it will be charged to 5V. When you first start charging, it will charge at the highest rate available (by supply restraint, charge controller, wire size, connector conductivity) and as the battery becomes more & more charged, the charge rate (current flow) will drop, and when fully charged, the current drops to zero (0). The chargers are rated at what they can safely supply, 1A, 500mA, 2.1A, 850mA, etc without damaging the charger itself-some chargers are smart and limit the current, others will supply what they can and suffer damage if more current is drawn than the charger is rated for (ex: Harbor Freight unit with shorted data pins put out 1.1A (rated 0.5A) and started melting parts before I shut it off). I tested an 'Apple compatible' charger rated at 2.1A and it would only charge at around 600mA unless I shorted the data pins, then it put out whatever the NC would draw, up to a measured max of ~1850mA.
Oh, Snap!

Longer USB Charge Cable

Anyone know of a good quality usb charging cable that will charge the phone at full power, isn't super expensive, and is longer than the stock one? The one that comes with this phone is just too short for me. I even tried my galaxy nexus usb cable, but it the phone says it is charging at a slower rate.
I'm using my Charge's cable with the LG adapter and the charging is quick as heck. BTW, I went from the Charge to GNex to G2 as well lol. Loved each upgrade!!

Quality is awesome and they are about 1.5m long. Stable for data and charging. :good:
I'm just using a cheap USB extension cable inbetween the LG charger and stock usb cable. Works fine, charges fast, doesn't give the "slow charge" notification.
I agree with the USB extension cable. I really dislike the durablity of micro USB, so I would rather use the stock cable with an extension than a cheaper built long cable.

I have an HP Touchpad, and it comes with a cable that looks identical to this. When I try to charge my phone with it, I get the "not compatible" message and charging is disabled to prevent damage... The cable may be different on the inside, but I would think the tablet cable would allow faster charging than the phone.
Alright... so far I have come across 3 different charging scenarios.
Charging with fading red LED - fast charge
Charging with white LED - medium charge
Charging with white LED + message "slow charge" - slow charge
I hope my interpretation is correct. So far I'm using my 2A original Asus charger from transformer prime and USB2.0 Palm-pre cable (which I posted above) and I'm getting fast charge (red glows, super speed). Now I only have this setup at work.. so I'm bearing with medium charge at home.
Trying not to use the original charger/cable, so I can have high resell value

Yeah seems like usb 3.0 cables have an extra connector that is not compatible with the G2. Can you possibly confirm that the cable you recommend will charge at full speed with the OEM LG charger? I'm wondering if it's either the charger itself that needs a certain cable or if there is something specific to the cable itself like the gauge of wire that is affecting charging speed.
I think you have to use the charger> 1.5A with good cable

Alright.. one thing I can confirm is that the charging speed depends on the charger.. not the cable.
I tried my fave Palm pre cable which I recommend into a slow charger and the message "slow charging" did come up.
And I also used this cable to the port that gives me medium speed.. and true enough, it was charging with white light, without the "slow charging" message. It is clearly following the charger, not the cable.
Electrically I don't see how cable should affect this. I know Samsung devices charges faster if the data+ and data- pins are shorted. Not sure about these LG ones. However, charging happens simply on the +/-5V lines.. it can't get any more complex than this.
---------- Post added at 01:10 PM ---------- Previous post was at 12:53 PM ----------
I just tested my McKal 2.1A charger, S3 original charger 1A and HTC original 1A charger.
All of these did not say slow charging, but they didn't have the glowing red LED (fast charging) either.
I guess I'm lucky I have my Asus transformer prime charger to get fast charging..
I know this Asus charger is a USB3 one, BUT only Asus propriety cable for the Prime tablet uses the USB3 pins. I'm sure that my cable is not a USB3 one.
I would like to know specifically a charger I can buy on Amazon prime preferably, that will fast charge... (car charger) I don't want to guess... so who has one that works- that you own and use and KNOW works.

I hate to argue with you, but that's not what I am seeing here.
Using the LG charger and cable, I get fast charge.
Using the LG charger and any other cable, it immediately gives me slow charge. I've tried about five different USB cables. A BlackBerry branded one, a Duracell one, the white Amazon Kindle one, an old HTC one, and my old GNex cable. The only one that gives me fast charge is the LG supplied cable.
I bought a USB power dongle that has selectable modes of operation (Samsung charge, Apple charge, and "data pass-through") and will deliver 2.1 amps from a standard USB port. It's Chinese made so I know there might be danger of blowing the power on a USB port, but it's what I've got to test with. I can't get this phone to fast charge in any mode at all. With the GNex, it charges fast. With my iPad, no sweat.
I can confirm this. Charging speed definitely depends on the cable. Here it's the same as with you - the only cable that delivers full charging speed (approx. 1600mAh according to BMW) is the supplied LG cable. The worst one (100mAh) is an old Kindle cable. All other cables I have are somewhere between that. None is "faster" than 1000mAh. The main visible difference between the LG cable and the other cables is the thickness. The LG cable is the most thickest. From my other cables, the ones that reaches approx. 1000mAh are also quite thick (but not as thick as the LG cable).
Then I received my free LG PD233 Photo Printer today (amazon preorder offering). It comes with a 1200mAh charger (the G2's charger has 1800mAh) and a very similar looking cable. It's a bit shorter and white. With this cable I have the same full charging performance.
So obviously LG spend some more cents on better-quality cables. However, given that there are plenty of high-power wall and car chargers (with 2000mAh and up) available on the market, one should assume that there should also be cables available that can be used with this chargers. I just didn't managed to find one yet.
I use a USB extension cable to charge the phone battery takes 5 hours, while normal rechargeable battery takes only 2 hours

I completely agree, I've also noticed is that the LG supplied cable is unusually thick gauge wire compared to other micro usb cables. It's 20 gauge wiring and fairly short, which means that it has extremely low resistance to current. I mean unusual, in that I literally cannot find any micro usb cables that thick for sale and I have been searching online. Part of the problem is that cables are usually not listed online in terms of the gauge of wire, which combines with the fact that micro usb cables that thick aren't common, yet. That's probably the reason that no cables that people are trying are working with the stock lg charger at full charge.
If anyone can find or knows where to buy 20 AWG micro usb cables or thicker, please post the source here.
The cable for the G2 is a lower gauge because of the higher amperage charge rate. Which is why the GNex (what i upgraded from too) cable charges slower, its only guaged to be sufficient enough to carry a .15A charge rate. The G2 charge rate is .3A, hence the reason why they used a larger cable.
So, the G2 can recognize the resistance and slow down charging on lower-gauge cables it seems? How very UA-approved of them...
Now, the hunt is on to find heavy gauge micro USB cable...
Perhaps this?
http://www.monoprice.com/products/p...=10303&cs_id=1030307&p_id=8639&seq=1&format=2
I've been looking for a 24/20 AWG micro USB cable for a while now. I haven't been able to find one.
Interesting find you guys..
Guess I was wrong after all. Also something to note is that with my fast charging cable directly connected to the phone, all is well. When I run it through my Samsung S4 charging dock, it slows down.
Perhaps it's time to email LG about this? Would be a valuable question..
Also, I still stand by the fact that my palm-Pre cable is capable of fast charging, at least with my Asus transformer prime charger. I haven't even started using the original charger/cable..
This is the exact package which I ordered:

Criteria for charging amps

Hi,
Does anyone know why it is such a god damn crapshoot for charging speeds on the galaxy note 2 (or any samsung device for that matter).'
You buy a charger rated for 2amps and you never know what it will give you.
You buy a USB micro cable and get anywhere between 0.4amps and 1.6amps.
What is the criteria that the phone is using to determine how many amps to pull from the charger? How does it even know what gauge of wire it is? Is there some sort of resistance check?
I have a Galaxy Note 10.1 and that is even more particular than the GN2. With most aftermarket chargers, it absolutely refuses to charge. I've had so much trouble finding a charger for it I've just stopped using the tablet since I only have one working charger for it.
It really sucks spending anywhere between $2-$30 dollars on a charger and not knowing if it will work. My success rate has been less than 10%.
I try to do forum and google searches, but all I seem to find are comments like "I bought this charger. Seems to work." With no detailed information on what performance they are getting out of it.
This is really turning me off samsung products. I don't have this problem with my HTC or LG android devices.
I don't know why you have problems, I have 2 samsung devices (phones) and I chare them with their original chargers, charger from Nexus 7 and my old charger from Desire HD and all work just fine... ofcourse, the original one is the fastest, since it is 2A, HTC one is 750mA and Ativ S one is 500mA, N7 one is 1A....

Your stock charger is 2A. (about 1.5-2 hours to charge)
Your HTC charger is 750mA (about 4-5 hours to charge)
Your ATV charger is 500mA (no better than a computer port. 6-8 hours to charge)
This was my point. This IS my problem. Obviously the stock charger works at 2A, but with any other charger it is anyones guess as to what speeds you're going to get out of it. Even when they are specified to work at 2A, you are likely not going to get 2A out of it. The phone is so bloody fickle.
If there was some benchmark or specific set of criteria I could use when I purchase a new charger to know for certain if it will charge at 2A, then that would mitigate some of the problem at least. But right now, there is none as far as I can tell. When I purchase a charger, I literally have no idea if it will run at 2A with this phone.
I'm glad that you're not bothered by the slow charging speeds and are happy with <1A. I'm sure this works well for most people. It doesn't for me. I push my phone to the max (as I have every right to) and need a charger that can keep up.
Well, charging slowly is different to what you say i.e. "refusing to charge at all" etc. And of course I don't use Ativ's charger to charge N2 often, it would take ages But I use HTC's charger that is 750mA and it charges within 2 hours which is OK.
Anyways, the only solution for you is to buy BRANDED charger from a company you can trust not some cheap chinese, t should work just fine whether it gives 2A or 1.9A is really no big difference.

Well, there are chargers that refuse to work. Especially with the Galaxy Note 10.1.
Cheap ebay chargers are a crapshoot, that much goes without saying. But there are many brand-name chargers that don't work at full speed, despite being rated for 2A.
Its not so much a charger thing as a samsung thing. While I'm not able to find specific criteria as to how/why the phone decides to charge at the speed it does (which is really the only question I had with this thread), I can tell you that there are many brand name products (monoprice, anker, ngear, etc) that are rated for 2A, but will not run at 2A with the samsung. They will usually run at 2A with other products though.
The more research I do, the more I highly suspect that this is a case of Samsung propriety. It looks like that they are deliberately throttling aftermarket chargers to force you to buy their overpriced samsung chargers. As I understand it, it has something to do with creating a voltage divider between two of the contacts, but every diagram I find shows a different wiring scheme. This would indicate that no one really knows for sure.
The one and ONLY question I have with this thread is to find out what criteria the N7100 uses to determine how much amperage to draw. I remain confident that no one will answer this question because it seems no one knows.
For the Note 2: there is a way to get a simple measurement of how much current is being pulled. Refer to this thread for the apk and more info.

Thanks for posting this. I suppose I should have mentioned that I have this app already and it is incredibly useful. I also have this, which with only a few bizarre exceptions, reports the same as the app.
The more people who are aware of this app, the better. People who think that their aftermarket charger "works fine for me" are probably unaware of how much those chargers are under-performing.
I don't have the education to explain your situation your situation well. But it boils down the electrical engineering the the physics of electricity.
There are quite a few variables that all effect the charging of devices. First thing is what does the device require for charge input, which is both amps and voltage. For whatever reason, quite a few tablets require 15 volts versus 5, which is what most mobile phones need. I have this same issue with my ASUS Transformer Infinity pad. It requires 2.0amps with 15 volts. I have a Galaxy Note II with needs 2.0amps with 5 volts. Unfortunately, when I use my phone charger with the tablet, it puts out enough to trigger a charger is plugged in (turns on tablet if it is off), but not enough to trigger there is actual charging. It does charge it, but it's a trickle charge; basically if it using while plugged in, it only slows the battery depletion rate.
As for the charge output, now you're getting into build quality, resistance of the components of the charger itself and the USB cable being used.
And then depending the device, the pins used on the USB cable can have an effect too. This mostly occurs with tablets or proprietary cables because the pins may tell the hardware what kind of charger is being used, which may have built in limits for charging.
Hopefully that helps some.

That last part is correct. I actually know enough about electrical circuits to be pretty sure it is the phone deciding how much power to pull.
Ohms law states that the amperage of a circuit is the voltage of the circuit devided by the resistance (in ohms).
USB circuits are almost universally 5 volts. I remember reading somewhere that a phone has a potentiometer that protects it from circuits of incorrect voltage, up to a certain amount. This is probably why you can get away with sticking a 15V charger onto your phone and not blowing it up. You cannot depend on this however. Generally, you do not want to stick a charger into your device that is a different voltage rating than what the charger is rated for.
The charger decides the voltage, using an internal device that changes AC voltage (120VAC if youre american) to 5VDC (USB) or whatever your device needs. This device is called a rectifier.
As stated above, the charger decides the voltage. The battery determines the resistance*, therefore the amperage is the natural result of deviding the voltage by the resistance.
*Resistance is added to the circuit by the wire and the charger itself, but is usually inconsequential.
When a charger says that it is rated for a certain amperage, that means that it is the maximum amount of current that thr internal components can handle safely, without running the risk of earth-shattering kabooms (fire). If the circuit you have connected to your charger contains too little resistance, you will increase the amperage (ohms law, as stated above), and you may end up with a piece of charcoal where your charger used to be.
Thr fact that the samaung phones can change the amperage of a charging circuit so fickly must mean the phone is capable of changing its resistance. So the question becomes, what criteria is it using to determine when to change the resistancr and to what?

This may be the longest thing ive ever typed on my phone.
I'm not disagreeing since, as you said, the mobile device manufactures have build in some safe guards so we don't fry them from incorrect chargers or over charging.
But there are charges that are 15v. I've have one that came with my ASUS Transformer Infinity Pad. I think many Samsung tablets are in the same boat. I don't recall using that charger on any of my smartphones; if I have, it's only been once or twice, but good possibility I may never have. But as stated earlier, I have used my phone chargers on the tablet, but only does a trickle charge. That tablet has some wide input plug at the end of the USB cord. I'm thinking one of the pins must not get enough power to trigger the full charge. Yet, if I use my Anker external battery, set it to 15v, and a few adapters, it triggers the normal charge cycle.
Don't forget,phones such as Galaxy Note 2, Galaxy S3, use 11pin microUSB ports versus the standard 5. I have no idea what all pins do or trigger, My assumption, part of your answer why the charge output varies lies with how they're use the other pins. I know quite a few tablets have more than 5 pins since the USB port is some wide thing; the ASUS does because it carries data and power for the separate keyboard that can be attached to be a suedo-laptop that has USB ports, battery and full 104 key keyboard; I don't recall what other ports the attachment may have.
I still hold that part of charge difference is also the USB cord itself since difference materials have difference resistance. It may not be as significant as the charger itself, but I've seen significant differences in charging times or depletion rates (around 10% battery per hour) using MHL adapters purely on the USB cables.
Yes, typing out long replies on the phone's virtual keyboard blows monkey chunks. Thus, I use a blue tooth keyboard instead for those situations. I also have a blue tooth mouse, LOL.

USB cable that can run at 1800mA

I've managed to find some chargers (both car and wall) that will charge with 1800mA (according to Galaxy Charging Lite app).
I have not managed to find an aftermarket cable that will charge at more than 1amp. Anyone know of an aftermarket cable that actually is capable of 1800mA? I've tried nGear and monoprice, and while they are very well constructed cables, they will only charge at 1amp or less with the n7100
Thanks for the help in advance, but please only respond to this if you've actually tested the cable with with the Galaxy Charging app or a current meter of some sort. I'm not interested in cables that only work anecdotally.
-PW
I'm breaking your rules (gasp) but as far as I'm aware, it's not the cable that manages the charge, it's the power adapter that feeds the usb, right? I've used all sorts of random cables on my travels for work, but always sticking to my 2+ amp output charger, and they've always worked.

Find a very short cable and you'll see rates up to 2100 ma (as measure by battery monitor widget). I use the short usb cable that came with my jambox combined with the the phones stock charger. The charger gets so hot due to the high current that I worry if it might burn out. The cable is very short, like 6 inches. I use this one when i need a quick bump before going out.
At this low of voltage plus high current, the shielding on most cables is not enough to protect against the voltage fluctuations caused by the high magnetic field. The longer the cable the more shielding is needed. Additionally, the cable shielding gets less effective as the cable gets older due to general wear. My original usb cable can only due around 740 - 1250ma, where it used to do 1800ma when new nearly 2 years ago.
If you could find a cable where there the positive and negative wires are separated in parallel strands like traditional AC power cords, it would also help. I have a cheap charger with built in cord like this and it charges consistently fast.

Most USB cables will work with the charger, but some cables (usually longer or smaller gauge wires) will restrict the charge to a lower amperage. I still haven't quite figured out how the phone knows what cable is being used, because, realistically, in a simple DC circuit, the consequence of using a cable that is too small is heating up or burning out. A cable that is too small alone will not prevent too much amperage from going through itself. This is why they invented fuses. Somehow the phone detects the gauge/length of cable being used and restricts the amperage being pulled from the charger by changing its own resistance on the circuit.

I suspect you're right. The impedance of a cable is the only thing that would change over a period of time that would result in a cable that could once pull 2A to start pulling less than that. Still, it would be nice to have a list of chargers/cables that consistently pull 2A before dropping $15-$30 on one of them. There exists such a list on this forum, but it is filled with comments like "It's good enough for me", without any real data as to what performance they are getting. Hence my rules above.
The charge rate depends on your kernal not the cable. I use Agni and get over 2 amp charges from a USB cable I paid 12 cents shipped for on eBay.
I purchased this cable about two weeks ago and it delivers!! I can charge my 9300mah Zero Lemon battery from 0-100 in just under 4 hours. Stock battery in about 1.5-2hrs. Of course I'm using a 2.1 amp charger, but NONE of my other cables come close. I'm averaging 1800-1900mah charge rate with it. Next highest rate cord only gets about 1200 max. I plan on ordering 2-3 more. $5 and change with PRIME.

Thank you! This is exactly the type of review I was looking for!
:laugh:
Check this out. http://voyager8.blogspot.com/2013/04/how-to-choose-good-usb-data-and.htmlI found it while looking for the 6ft cable I used to use until it shorted from heavy use (bending a lot) and I got a pack of 10 short flat wire style 3ft cables. My 6ft one has a ferrite end and printed on it: 28agw/1p and 26awg/2c. It could handle 2A just fine, but this requires any wall outlet adapter that can output that amperage. The oem outlet adapter that comes with the phone says 2.0A output, but you can fine any 'reliable' one that has 2.0A output.
if the original cable is not 1800mA, there must be a reason
Get one of these

some fake cable limit current.
Got similar problems as the OP. I wanted to charge my phone in my car and using the phone as a navigation device without depleting the battery (which occured a few time).
Tried several usb cables, even did some mods like shorting the white and green data wire in the cabel at the phone side, but that all didn't help.
Then i came to Kopi who sells usb cables which can deliver a full current.

I believe it has to be a "charge and sync" cable. I have some charge only cables that came with small micro-USB powered devices that fail to fast charge, but a generic USB cable does. The charge-only cables don't need to pass data because the devices they came with only use them for power so it looks like you have to have the data lines intact.
I also got some nice micro-USB cables at Best Buy that have nice LED lights in them. The Pt brand one with just an LED light at the micro-USB end was able to fast charge, but got extremely hot. The other brand (Modal) that had LED lights all along the length of it failed to fast charge. I'm guessing that either the drain of all of those LEDs or the fact that they are powered by a chip on one end of the cable means that they force the USB connection to only supply the basic power. Both are going back to BB.
I found a nice USB "charge and sync" cable at Walgreens that spring coils into a housing (the round housing has a regular USB plug coming out one side and a micro USB plug coming out the other end and if you pull on them they extend equally - pull again and they retract together to lie flush with the housing). That one does fast charge. It is replacing (along with a cheap 2.4amp car charger that was almost as fast as an QC2.0 charger) an old cheap retractable car charger that I used to use on trips that failed to even keep up with the power drain of navigation on the S6edge or my S5. The retractable cable is not listed on Walgreens web site and I found it behind the photo counter in a bin of USB chargers and cables.

It's only 2 feet long fully extended, but it packs nicely. Unless you are looking for something that packs away nicely without tangling, I would think you might find some nicer and cheaper cables elsewhere, although this one was only $10.
I'd buy the Anker. Can't go wrong with them.
My own issue is I have too many of them!
Got the 15Ah on sale for $30 earlier this year.
That new one is 20Ah, ridiculous capacity!
But needed on excursions with ipads, etc.
Not a big deal if it doesn't charge as fast. I'm tempted to buy it and use galaxy charge current and compare rates with the included wall charger. Of course current doesn't mean squat if we don't know what rail it's on, i.e. 1.5A at 9V is better than 2V at 5V.
EDIT: How about LUDICROUS capacity for same price as the older version?

I have 3 different quick chargers around and none of them charge at a different rate with the different cables I have laying around except for the long cables. I use them generically between the chargers, pc, various devices.
As to the long cables (3 plus meter) charge times slow down on the few I've tried. Not huge but noticeable.

There are 2 things to note here. The phone will say whether or not it is fast charging and it will also show a prediction for how long it will take to get 100%. You can actually get a reasonably quick "time to full" estimate on a basic charger that supplies higher amperage, but I believe you will only get the "10 minutes for 4 hours" boost from an actual QC2.0 accessory that successfully negotiates the QC protocol with the charger. The QC2.0 protocol involves not just higher amperage, but higher voltage, which likely makes the difference for that boost.
So, when you say you have 3 different "quick chargers" around, do you mean "officially Qualcomm QuickCharge 2.0 accessories", or a charger that is higher amperage than normal and so uses the words quick and charge on the box.
Having said that, I've seen basic 2+ amp chargers that are fairly common where the phone predicts a total charge time to 100% that is very close to what I get on the adaptive charger or whenever the phone claims it is fast charging (only ever on an official QC2.0 accessory with the right cable). I think the only real difference is offering the initial boost of 4 hours for 10 minutes, but in the long run "actual QC 2.0" is not that much better than any high amperage charger for a full charge because the charge rate is not linear as the phone approaches 100%. This is the same reason why DC charging for EVs never lists the time to full because they'll get you to 50-80% in half an hour and then take another 2 hours to get you to 100%. The speed enabled by the high voltage is only an initial boost and matters little for a full charge.
The reason I would want an actual QC2.0 charger for the car or for an external battery pack is that I often jump in the car for a 10 minute trip when I'm getting low and it would be nice to get a significant charge during that time. With an external battery, having QC2.0 would mean less time having to keep the phone tethered to a brick. Otherwise, if you are only looking for a full charge then an official QC2.0 vs a high amperage charger isn't that big of a deal.
I'm an engineer. I have three qualcomm quick charge 2.0 chargers, one Oppo charger with their competing (and better ) technology, and uncounted random chargers from unknown past phones. Some more potent and some less. Yes, each of those qualcomm quick chargers will respond to the embedded controller on the phone and provide quick charging, the phone will note such when plugged in and notify to that effect. Yes, they make quick charge 2.0 car chargers and I also have one of those and yes it charges at the same rate as the 120 chargers in the house.
I'm a bit of a slut when it comes to these things.
That's great. Keep in mind that the only reason I asked is that there are plenty of packages out there that use the term "quick charge" in a generic sense and so I usually specify QC2.0 when I mean QC2.0 to differentiate.
But, back to the original question - you were indicating that all of the USB cables you have tried all seemed to charge at the same rate. I will reiterate that I have found micro USB cables that do not pass QC2.0 and the phone will back off to a nominal rate when they are used. Usually the cable is special in some way, for example:
two cables that I believe came with my Chromecast - they have one of those "ferrite core" style bulges in the wire (pictured below) and were only originally intended to provide minimal USB power to the Chromecast (no data)
a Modal LED lighted "charge and sync" cable from Best Buy - since the LEDs animate to show power flow, there are obviously some electronics in the plug/wire to sequence them, and whether or not that was the reason, they did in fact prevent QC2.0 from engaging (the phone did not show a "fast charging" status).
As such, I'd look for cables that include both "charge and sync" (most do) and I'd avoid anything active in the cable, like an LED light. Having said that, the Pt brand lighted cable (also from BB) that has just a solid white LED only at the micro USB end did seem to allow fast charging, but it got very hot so I didn't really like it in the end - but it does show that there are some non-passive USB cables that will still work with QC2.0.
Chromecast cable:
I went to a couple of Samsung shops here in Taiwan and they were out of those new chargers for fast charge. They were only selling the regular chargers from before. Salesmen also said he heard something about the new chargers causing damage to the smartphone (sensors). He was not sure he said but has heard about this issue. He could not confirm for sure said but he was pretty sure.

Frys has a large selection of retractable micro USB cables. I picked up a 2-pack of 3 foot cables yesterday and the phone indicates "fast charging" on them:
http://www.frys.com/product/6630234
Longer than the Walgreens cable and cheaper for 2 of them, but the cables on the Walgreens model seem a little beefier (which is likely why they only fit 2' of cord in the same retractable package).
I bought the Anker without reading the description well enough. :silly: It arrived and is almost the size of a Tablet! I returned it. So, don't be "underachieving Rob Lowe" and carefully READ before you buy!

I got the Anker E6 and it's a beastly size, but it completely charged my S6, from 5%, in ONE HOUR! I'll deal with the weight!
It's not the weight - I want pocket sized.
