Background: (feel free to skip this)
In my search to get a good car charger for my Nexus 10 (that would also be good on my Galaxy Nexus), I checked out a bunch of sites and manufacturers and reviews for the perfect charger. I also wanted it to be dual port for two phones at the same time in case my girlfriend is in the car.
So many 2A chargers are not actually 2A, they may be 1A to each port max or they may only work as 2A on an iPad. Android devices look for shorted out data connections in order to pull more than USB power (500ma). So a charger has to both offer 2A or more and have the data pins shorted in order for us to get maximum current to our Nexus 10's. The Apple/iPad chargers work differently. They either have smart chips or specific resistances between the data pins in order to specify current draw.
-----
What you came here for:
After the long search, the BEST while still very affordable car adapter, is the *drumroll*:
Bracketron Universal Dual USB Car Adapter
2 ports like I wanted. 2A like I wanted.
Contrary to the "Universal" listing, the adapter was likely made for the iPad. So charging out of the box is USB (500ma). But it's easily fixed in under 3 minutes!
---
Instructions:
1. Pop off the round silver plate on the front (with your finger/nail).
2. Unscrew the silver part in the back. Don't lose the spring hidden inside.
3. Slowly pry open the black plastic. It's fairly rigid and you'll hear some clicks. If you don't open it like a crazy monkey, you won't damage or break any plastic.
4. You'll see by each USB port 4 wires going to the port from the circuit board. The 2 middle pins are the data lines, the 2 outer ones are the power lines.
5***. You want to short the data (two middle) pins. All that means is you want them touching electrically. Takes about 10 seconds to do with a solder iron (once it's hot ). Just flow some solder between the two pins, no wire needed. Do the same for the other USB port on the other side.
6. Put the plastic and screwed pieces back together. Plug it in and you should see AC charging! :victory:
***If you're poor at soldering, don't worry - you're doing this on pins in the air, not directly on the board, so it's an extremely easy soldering job. If you've never soldered in your life, you can possibly use some wire instead of solder to connect the two and find a way for it to hold in place. But seriously it's an easy solder job and you should probably learn how to solder anyway.
---
Reading the instructions I wrote takes longer than making the modification.
Why this adapter if you have to solder? It's the only one I can find with dual ports that can actually give 2A to an ANDROID device. Why this of all the other adapters you can attempt to solder? It comes apart extremely easily so you don't break any plastic like many of the other ones. And the adapter is really small so you don't have a huge piece of plastic hanging out of your power port.
Fair note: it looks like it may give 2A max, so charging both my 1A phone and my 2A tablet will actually be slower. But it's perfect for charging the tablet at full speed when by itself or two phones at full speed.
Also, credit to Amazon reviewer 'K. Crawford' for suggesting this adapter as a good one to mod.
If anyone needs help during the process, I'm more than happy to help!
Very nice info, thanks.
Niiice! I heard though even if you hook up the tablet to a 2A charger, the tab will still only take a reduced amount, is that true?
From my measurements, the tablet will draw around 750 ma, so soldering it will help, just not for the full 2A.

You measured 750 ma with the bracketron I linked post-mod?? It should be much higher.. What did you use to measure?
nice instructions, royal.
did I do it right?! check the details beneath one of the photos. you will see some solder popped and landed on the circuit board on the top right. it is touching one of those little enclosed boxes on its own and nothing else. you think this is gonna pose a problem?! if so, any fix? I tried to pull it away, but im not a mastersolderer.
bummer about the picture rule. I think I got some good shots that could help some people. I guess I'll be back to post the pics.

It doesn't state if it's "shared" or not. Meaning is that 2.1A total for both or 2.1A each. Lot of them are shared even at 3.1A.

With the iPad designation, it's a sure thing that this will need modification. If I'm understanding you correctly, I think you're trying to suggest modified (data-shorted) cables rather than modified adapter. I prefer having a modified adapter so I can use and replace cables at a whim. But if you purchased that one already, you can see if it comes apart and can be modified just as easily.

I purchased a Kensington car charger packaged for an iPad and all that meant is that it came a iPad type cord but still a standard USB port which worked on my Android device.
Some people have said that the cable used also has a lot to do with what the tablet pulls. Some saying a Motorola brand USB cable they had gave much more current. If there is any truth to this then in conjunction with doing this mod to the charger it might be a good idea to buy a cable with 22AWG power conductors:

The question isn't whether the port is USB. It's always going to be USB supplying 5V. The question is how much current the device can pull from the charger. A normal USB port (like a computer) can only supply 500mA by spec. The N10 needs 2A. The ones designated for ipad will usually charge your N10 but at a max of 500mA (even if they're rated higher - because the data pins aren't shorted).

If the data pins aren't shorted, it won't draw more than 500ma, if that's so, how can it be rated at 2.A? I haven't tried my PS with the Nexus 10 yet but did with my other device, had no problem but it has a much smaller battery and I don't remember the details.
I'll try to check it out on the Nexus 10 and post the results.
EDIT
I thried my Kensington or this one: http://www.amazon.com/Kindle-PowerB...158903&sr=1-7&keywords=kensington+car+charger.
I first tried it using a POGO cord and it wouldn't charge. It did using a micro-USB cord over 500ma also.

I explained it all in the Original Post, but I'll try to clarify. If a charger is rated at 2A but doesn't have data pins shorted, the Nexus 10 will only pull 500mA. The manufacturer isn't necessarily lying about the 2A, it likely is capable of giving 2A. However, the Nexus 10 checks for shorted pins before pulling at 2A. This is because USB spec is rated for 500mA and if the Nexus 10 tried to pull 2A from a computer, it would overload the circuits of a computer's USB port and potentially damage the USB hub or computer. So as a somewhat universal decision (though really it's not standardized), most manufacturers did something like this: if data pins are not shorted (as in a computer) - take upto 500mA. If data pins are shorted (as in the charger provided with the device) - take upto what's necessary. This is actually a somewhat problematic solution because a 2A-requiring Nexus 10 plugged into, say, a Galaxy Nexus charger (shorted data but only 1A) could potentially cause damage from overloading.
Therefore, Apple didn't go along with the whole shorting the data pins solution. They came up with their own solution, which I actually don't know enough about to speak of in accuracy. But their solution allows the device to basically "sense" the capabilities of a charger, so it knows whether it can charge 1A or 2A or 3A, etc. This is I imagine is either done with resistors specifying discrete values or with some sort of "smart chips".
So, as you see, the Apple ones don't have shorted data pins. Therefore a manufacturer of a car charger has to decide: Support Apple devices or support other devices? And some manufacturers do such a bad job, they provide the high current (like 2A) but then don't do Apple's "solution" or the data shorting, thereby rendering their high current useless.

If you were to use a PS limited to 1A, it "should" have a saftey to limit that. I used my above mentioned 2.1A PS with a 110VAC>12VDC adapter which was has a 1A max. and it did limit the output. Not saying that all PS would do that without damage though.
While poking around in files, I did find one that lists the power source by name but I forget as to what it showed for the OEM PS. I wonder what it'll show for a car PS?
Sv: Best 2A car charger: Bracketron
I doubt there are phone chargers without current limitations as safety feature. If designed well the charger should limit the current at its max current. Otherwise a lot of chargers would burn.
But I am not sure this is the reality

I believe Apple use a pair of different value resistors to create a voltage divider, passing a different voltage to D+ and D-. The presence of this differential voltage on the data pins is what triggers the high power charge capabilities.
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.

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.

Bought a few for 6 dollar each and am now a happy camper.

CHOETECH 6 Port 60W Multi USB Charger with two dedicated Quick Charge 2.0 Ports Charger with Qualcomm Technology
http://www.choetech.com/choetech-multi-6-ports-usb-charger-quick-charge-2/
Thanks for compiling this. I emailed Anker about the Astro Pro2 ad unfortunately it does not support Qualcomm Quick Charge 2.0. They said that PowerIQ is different and doesn't charge as fast. I think the only ones that will do Fast Charge are ones certified as such.
That being said, I'm in for the Aukey.
I've been looking to buy the Aukey but its unavailable from Amazon right now
is the usb cable has to be different as well? couldnt be a normal usb cable to do fast charging??

i don't believe the wire has have anything to do with it.
which is faster, 9v 1.67 amps or 5v 2 amps? also, anyone come across a powerbank that has wireless charging AND fast charging?
one question that it seams i dont find in numerous searches i did, does the wall adapter from samsung lights any green light when starts to give fast charging? because i did see something similar but maybe was not the samsung wall charger.
thanks in advanced.

...that is per 3000 unit orders.
I have a Mophie, Powerbrick XL (12,000 ah) or something or other. Not cheap but it puts out 2.4X2.4 (two usb outputs) simultaneously. As I said not cheap but telling the ol lady her phone will have to die while she watches mine charge on the airplane is simply not a place I want to visit.

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.

E-filliate brand Retractable Charge & Sync Cable for Micro-USB
Model #1311653 (?)
UPC: 8 26341 02003 9
The Walgreens web site shows other E-filliate brand cables in bright colors, but not this one. It was not in the case with the other phone accessories, it was behind the photo counter in a plastic bin full of an assortment of colorful chargers and cables that looked like the kind of thing you'd find on the counter next to a checkout stand. 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.

The 3 foot cable was confirmed working on the op3 forum, I have not tried that one but I have personally bought and tested the 6 foot and can confirm that it supports dash charging. At 6 bucks this is a very inexpensive option to extend the stock cable. It also fits very tightly and I am not worried about it coming apart. (At least for now.)
Amazon
These are good news! Thanks!
hmm its a pretty long cable, would it affect the charging speed ?
if yes how much in terms of charging from 0-50 and 0-100 compared to the stock cable without extension
I have a 6ft monoprice extension that allows the phone to register dash charge but still only charges at standard rate. It's like the AC adapter can still tell the difference.

I meant with Ampere both these setups show the same.
Samsung + micro + micro to c adapter
Stock + Stock cable
So I figured the app is not reading dash correctly if that other setup states the same speeds.

I'm not sure what you're saying here.
Extension cables work with QC2.0 and 3.0 perfectly fine. I used my monoprice 6ft USB3.0 with my Nexus 6 and it worked fine. Ampere registered about 2300mA with the N6 when quick charging. This was just about the same rating that I achieved with the stock cable and no extension.
The case of the OP3 is different. With the stock cable connected directly to the Dash Charger, Ampere registers about 3300-3400mA. With the 6ft extension in place, the phone shows "Dash Charging" on the lock screen and I get the blue Dash Charge LED charging light, but Ampere only registers about 1300mA charging.
Anyone tried this oppo vooc cable with the dash charge adaptor?

If 1300mA then no Dash. You got yar self an answah
Its about the juice not about the info...
BTW... If you get a 20 ft long "Dash cable'' probably the cable resistance will be so high that you could get max 300mA that's why 1+ will never produce 20ft USB..

I wasn't asking anything. I already know dash charge wasn't happening. I just want people to know that even though the phone registers "Dash Charging" on the lockscreen, it isn't really happening with an extension.
Nobody is asking OnePlus to produce a 20ft dash cable. There's just simply no reason why we shouldn't be able to get a 2M cable. The loss due to additional resistance would be negligible.

I personally hate the 1m (and even more so when it comes to shorter) cables. Can't play with the phone while charging, because no jacks are ever close enough that the cable reaches the closest seating option (orher than the all present floor ) . Even in office the charger is relatively close, but when I answer the phone the cable is too short.
2m would be perfection for me at least. I know it's too long for some, but then again I'm talking about a choice to order one.
And as biglilsteve said, there is no elecro-physical limit to this 2m cable, and if the heating (if resistance grows the cable heats more) should become an issue the cable could be designed to compensate it with thicker copper (and that would be something like 10%+20% thicker I assume)
3010 mA
Just got the 3m Sabrent extension in yesterday and very pleased with the speed. I'll take it.
Screenshot isn't uploading from my phone for some reason but I got 3010 mA on Ampere.
At this point I'm quite confused about it the ability to use a extension. I want to charge my OP3 comfortably. So if I buy a USB 3.0 extension from Anker, Aukey, Amazon Basics or another brand it will charge I know that. But it will be Dash Charge or Traditional charge? Thanks

Don't know about others, but I personally can tell you dash charge works with the extension mentioned in the OP. You lose a couple hundred mA of charging speed, but still get around 3000 mA, which is the speed that QC3.0 runs. Perfectly acceptable!
The one I bought from Amazon.in->
http://www.amazon.in/Baseus-passed-...scsubtag=d1ee5b2c-e3c5-4567-8fa3-e99d4138e818
I bought 3 and haven't had any issues. Details in another thread.
I bought one cable from a chinese dealer on ebay for 1€. Other third party cables starting from ~4€ in Germany. It's working perfectly, no need to spend more money.
People are commenting here that the cheap cables are working, but the question is "is it safe to use".
here is a list with proven safe to use usb cables:
http://forum.xda-developers.com/oneplus-3/accessories/safe-usb-c-compliant-cables-adapters-t3401820
these are all tested because there is a problem in cheap USB-C 3.0 cables, however the OP3 doesn't have usb 3.0.
I'd recommend to buy a cable/adapter from the list, its maybe $5 more expensive but you are sure you are safe.
What else is the issue than giving too much power to the phone? I tested my cables and charging limit is good, within charger's limits (2A charger, phone gets 1,4-1,6A).
I only buy the ones that Benson Leung recommends. he is a google employee who fried a pixel c with a bad cheap cable, and since that happened, he reviews on amazon and provides a pass or fail based on the correct implementation of USB C protocol within the cable/adapter/whatnot. https://plus.google.com/+BensonLeung
I got some Monoprice cables in and they charge fairly fast still even from the computer USB. It seems to stop charging about 85% but I'm good with that as this is for work and the car anyway.
but what is the definition of unsafe USB C cable?
A fake charger can be dangerous and they are weak anyway but a fake USB C, what's the risk?
I mean to cut the cost they could use low gauge wire, meaning the cable have high electrical resistance.
But a high resistance mean a low charging power and charging a battery slowly is safer.

using the wrong spec for usb c cables (regardless of charging or not) can damage the port itself. Typically, if its an OTG, i dont think you will see the issue, but folks were using non-compliant cables with chargers and frying their devices.
I see, there is a controler in the cable head, unlike a normal usb cable. It make sense as this norm can allow usb C to usb C. For that new usb type, they copied apple...
I would say you shouldn't have a problems with any cable, just don't buy bad cheap ones.
Its no problem use cheap cable... Problem is use cheap cable and DASH charger. Because cheap cable is not built on such a stream. Threatens to burn cable.
used almost one month cable from ali with car charger, no problems, only charges a little bit slower. no heating, reboot and so on.
