can anybody confirm working portable power supplies?

I can confirm the iSound Power Max (18,000 mah) battery does not work.
Zagg Sparq 2.0 (6,000 mah) works if you're not using the optimized port, and the Solio Bolt solar charger (2,200 mah) works as well.

Looking for alternatives too as my 6600mah Lenmar I've been using for my phone is a no go even though it has a 2.1amp. charges my kids ipad no problem.

The Samsung port on my Anker 10000mah unit works fine

Just be aware that it isn't always the portable charger that doesn't work but it could be the cable. Based on the few threads already discussing which aftermarket chargers and car chargers work, you can see a pretty strange pattern of some cables working with a charging unit while others don't.
Just an example, I was testing my 2A Griffin Car Charger last night and it didn't work with the stock cable (Cable that came with the N7). But once I tried it with the cable that came with my Portable Charger, it worked.

My New Trent IMP1000 works with the cable that came with it (retractable with interchangeable micro/mini tips) but not with other cables. That cable also works with several other chargers where other cables don't.

Zagg Sparq
I use this one: http://www.zagg.com/accessories/zaggsparq.php Right now they are giving free pair of 50 dollar headphones with it that are really nice!

I have a New Trent IMP500 and an Energizer PowertoGo. Both will only work if I use the cables and tips that were supplied with the power source. If the screen is on it says charging but the battery level seems to stay the same; if the the screen is off it charged 3% (from 83% to 86%) in 10 minutes - using the New Trent. I have not tested the Energizer yet.

The ZaggSparq is a piece of crap - it suffers from really bad battery drain. Unless you charge it weekly, it'll almost always be empty by the time you need it. I fell for the first generation, which was even worse. Then when they wouldn't replace it, I made the mistake of getting the new version - which STILL has the draining problem.
Get something better - like an Anker.

I picked up the New Trent 12000mah 2a portable power supply.
http://www.amazon.com/New-Trent-Thunderbolt-Blackberry-IMP120D/dp/B003ZBZ64Q
It comes with 2 cables:
-a standard USB to Micro USB (or whatever they call them that come with 99% of devices including the N7)
-what they call a Galaxy Adapter which is nothing more than a 2-3 inch USB extension that you can plug any USB cable in to including an iPad cable.
When i plugged the stock N7 cable in to the power supply (2a outlet) it didn't show as charging.
When i plugged in the standard USB cable that came with the power supply, again it didn't show as charging.
When i plugged in the stock N7 cable to the "galaxy adapter" and then in to the power supply, it did show as charging. Strange that the adapter made a difference but whatever at least it works.
When i plugged in another cable with multiple tips that came with my other Anker Portable charger, that worked too. No adapter required this time.
I did a test and confirmed that with the combinations that work, it is charging at the same rate as the stock wall charger.

The Anker 8000mAh I have charges the Nexus 7 at 2A. You have to use the Anker cable though.

New trent came in before anyone else, mine has been working for a good 3 years.

I like my Sparq a lot. Had it maybe 4 months. Got it on the recommendation of several friends who have all loved theirs. And frequently they are only 50 bucks.
The only issue I have is as stated in the first post, it doesn't work in the 2.1a port. But I haven't found any of the 2.1a chargers I've tried work.

samsung galaxy s5 charging time. 2.0(micro usb) 3.0 cable

hello members.
i posted this thread as i dint found any comparision time for chargin between 2 diffrent cables. 2.0 vs 3.0
i found the same charging time on both 2.0(regular micro usb) vs 3.0
it seems 3.0 only helps for very fast data transfers..
(hope this info is useful

Yup.. There will be no difference in charging time as there are no power pins in the extra Usb 3 lines.

..

I use USB 3.0 cables and it is much faster for both, charging and data transfer.

Download galaxy charging lite from the play store and check the incoming current. It's the same for microusb 2.0 & 3.0.
Maximum of 1800, usually charges at 1200 w/ screen on.
If you claim that charging is faster with the multipurpose cable, show screenshots.

I have both s5 and note3, tested with both USB 2.0 and USB 3.0 charger. It's just same output, time or charging current. Transfer speed, I didn't know because my PC not have USB 3.0 port

fffft said:
Your conclusion is misleading. You probably won't find a difference between USB 2 & 3 if you are using data cables as your phone limits it's draw to about 0.5A to protect lower specd USB ports.
If you want faster charging and in particular, take advantage of the higher current that is available from AC adapters or many newer USB 2/3 ports, then you need to use a charging cable. This is not the same as a data (multipurpose) cable. A charging cable has the data lines shorted to tell the phone that you are connected to a high current or at least protected source and it should go ahead and draw as much current as it can use (or is available if the port is current limited, but protected).
Of course, it should go without saying that if you use a power cable with a conventional USB 2 port, you are circumventing the safety protection and may damage your USB port.

This is interesting, my phone will recognize my (2 amp) AC charger as AC, yet with data cable it'll only go 550 ma according to that app (450 if recognized as USB). If I switch to a charging cable it'll take 1.2 amp from the same charger. Strange logic.

Well maybe its just me but my phone actually DOES seem to charge faster with the new 3.0. Like a lot faster.
Maybe it is "placebo" as you say but for me it really is faster. Just my 2cents.

the cable doesnt make any difference its the charger that needs to be higher

It's the charger that should be shorting out the data lines, not the cable. I would think that a cable that did this would pose a risk that, if inadvertently used to connect a phone to a regular USB port instead of a charger, could cause the phone to think it can draw more power than the port can safely provide, and subsequently overload and damage the USB hub.
Whereas a charger that shorts out the data lines can be used with any standard USB cable.
Maximum power ratings are a different matter, though. AFAIK, standard USB 2.0 connectors only need to be rated at 1.5A current to be compliant, but charging ports and cables (i.e. those compliant with the Battery Charging Specification) need to be rated to handle at least 5A - although, this is in spite of the maximum draw of 1.5A anyway.

with USB 3.0 and standard charger reached battery from 12 percent to 92 about 80 min
I've heard about 20% charging difference and I think it's true

This is about what I get with my supplied wall charger and cable. Its nice being able to use the phone and still get a charge at the same time. My Nexus 5 would only maintain a charge level and not gain any charge when being used.
One day last week I forgot my spare battery and had to use my mini USB cable I have at work connected to my computer and it took most of the day to go from 15% to full charge. The S5 has the best battery life out of any phone I've had so far but I wish they would release 4.4.4 for us as I saw a noticeable improvement in battery life with my Nexus 5 when i put 4.4.4 on it.

USB 3.0 Charging
So as most of you have come to realize, there is no difference in the basic way that USB 2.0 to USB 3.0 cables carry current to the device. The extra pins in a 3.0 cable are for full duplex, (bi-directional data transfer) at really fast speeds, up to 4 GB/s.
USB output is rated at 5V. The output current from different brand computers might reach 600ma. The current is regulated to avoid overheating the cable and computer power supply. The extra twisted pair of wire in a USB 3.0 cable enable a bit more current handling... up to 900ma.
The reason your newer Samsung charges the device faster is that the new power adapter (mine is white) has a current output of 2.0 Amps. The older power adapters had a rated output of 750ma, 3/4 of an amp. Result.. The new power adapter system facilitates fast charging.
I'm guessing that they spec'd the higher output charger to match the higher power usage profiles of the latest Samsung Galaxy products. I remain a fan of slow to medium charging rates to preserve the life and charge cycles of the battery. High rates yield more heat which can shorten the life of the cell structure.
Hope this explanation helps.

Take heed of this response - it's the most useful one here. There is no difference between charging via a usb 2 and usb 3 cable as long as both are decent quality (recommended 23awg gauge minimum for 2amps).
The extra usb 3 pins don't carry any additional power wires.
Ensure you're using good quality cables as mentioned above - look for 23awg (gauge of the wires within the cable) printed on the cable (all original and genuine Samsung cables are rated at this) and a 2A charger (again, recommended to use original and genuine Samsung charger) and there will be absolutely no difference between usb 2 and 3 cables.

usb 3 charges faster.
Those who say that usb 2 needs the same time as usb 3 don't know what they are talking about.
I won't talk or pretend that I know a lot about tech but here are some real results that doesn't come out of my head.
Usb 2 cables max amp is 450mha and I have tried 3 different cables a Motorola ,my HTC one X and a plain usb 2 cable that I have .All 3 of them gets 400 or 450 mha.
But when I use the original Samsung usb 3 ,a cheap China usb 3 or my black usb 3 from my external drive the Samsung let's 1800 mha to pass by.
All test are done with the original Samsung charger and a cheap 5 dollar one which I don't use much because when the phone is not charging it makes a weird sound.
And the only way what I say is not true is that my s5 detects the kind of usb I have and limits the charge which in result is the same thing.

There is no limit and this guy has no idea what he's talking about. There are no extra power wires in the usb cable - in both a usb2 & usb3 cables there is a positive and negative wire which provides power to the device period.
FYI, voltage and amps are 2 completely separate measurements which only compounds the stupidity of his response...

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.

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.

[Q] Is there a faster charging cable out there?

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.

Confirmed fast charging (3amp) battery pack?

So I am back again asking about power.
Since switching to my Nexus 5x I have had to redo all of my power supplies. I went ahead and pulled the trigger on the Google wall options but now I have a request for something portable.
What I am looking for is a battery pack that can output the 3amps to quickly charge the phone, I dont really care if it charges quickly itself. The reason being is I have a solar panel that can push 1-2 amps and I was planning on strapping it to the back of the bike or leaving it on the tent to charge the battery over time and then using the battery to charge the phone.

I actually just purchased this
http://www.amazon.com/gp/product/B00BQ5KHJW?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00
I got it for $21..99 on a lightening deal. Haven't tried it yet, but it outputs 3amps

I have an Anker Powercore 21000mAH external battery, using a USB A to C cable, Ampere reports charge rates up to approx 1700mAH. The lock screen reports charging rapidly.
The cable is a Pecham one, It appears to be good quality, nice and thick, braided cable and a positive fit at the 5x end. I was happy with the charging speed, having just read the google cable reviews thread not so sure.....

I own the Romoss Solo5, outputs at 2.1a and 1.5a. With a normal type C cable from CableMatters, I don't get rapid charging, but it does fill up faster than a generic usb charger.

Ill be curious to see what you get. My concern is they dont mention the specific output of the ports, just the overall 3 amp. I suspect its split across teh two ports in some fashion like most (where they can do 2 amps on a single port but then 1.5 across both)
I have a 2 amp charger but I am hoping for a 3 to get that max performance. The idea is I could use the phone for music, navigation, etc on the motorcycle and then get a very quick top up while breaking for lunch, etc.

You need a type C connector at both ends.
A USB type-C to type-A cable cannot and should not allow charging at more than 2A (0.5A for USB 2.0 standard), because that is the most allowed in the USB spec as mentioned by the Google engineer that's been reviewing Type-C cables on Amazon. In order to support 3A rapid charging you would need a battery pack with a type-C port on it that supports rapid charging. Even if a type-A port is capable of supplying 3+ amps, the phone will only charge at up to about 1.7A without the type-C port at both ends. I don't know of any battery packs that support the type-C spec yet, although I'm sure they're coming.

That is why I am asking. I dont care if it charges itself at 3amps because my sources wouldnt provide that anyway. Im looking for the battery pack itself to pump out 3 amps. Im holding out for one of those and until then I will work along with my existing ones.

Neat thing about this, you can use the OEM 5v 3a charger to charge it. Interesting to see if it charges faster than other options.

mysterious posted in the other thread that he/she ordered it. Im waiting with baited breath to hear the results. This might be the perfect all-rounder (dont really need the other ports but they dont hurt anything).
Could charge with my solar panels, could charge with the stock adapter and hopefully the phone quickly on a lunch break.

I love how none of these products ship to Canada, except the official Google stuff which is no out of stock.
