Hi,
I just stuck here, cause I found a thread about fast usb charging. But there is no answers or solutions.
I have many htc devices. It seems that some of them has a problem with 3rd party usb chargers.
My most used device is Universal. It suck a lot of power. THis one doesn't enable usb charging at all, until you put it in sleep mode before pluging the charger.
Anyway, the same issue for Kaiser too.
The problem is, that it doesn't matter how much current is the charger able to deliver. They just use some kind of recognition of original chargers.
What I already measured: Original charger and universal running => takes 1200mA. 3rd party charger or my 5A PSU => Universal/Kaiser sucks just 500mA.
This is fast/slow charge. I found here discussion about 4 and 5 pins shorted??
But WTF which 4 & 5 pin?
http://www.tracyandmatt.co.uk/blogs/index.php/2006/09/10/htc_hermes_usb_connector_pin_config
According to this pinout. It would be 2 GND of Audio side? I'm not sure that original charger use extUSB audio side to charge...? It also could be D & A pins, but I'm afraid to connect 5V to Data- pin.
Anyway, someone here have to know it.
If not, in a few days I'll try all possible combinations and post the results.
Thanks

I'd also be interested to know about this. When I charge my TYTN II via USB, it takes much longer to charge than if I charge it via the mains charger (I prefer USB since I travel a lot and it's one less charger I need to carry around).
Better still, is it possible to buy a USB cable that will charge at the same rate as the mains charger rather than messing with a USB cable with the associated risks?
Best,
Gary.

a usb port only supplies 500ma, while the wall charger does 1200ma as the OP has measured (although it says 1A at the back of the charger). changing a cable is not gonna superpower up your usb port.
unless maybe you get hold of a forked USB cable, like the one that Seagate Free Agent drives come supplied with... you know, 1 mini USB splitting halfway down to two normal USB plugs.
Worth experimenting with, do you think?

good call.......with a little googling i came up with this
http://www.universaluk.com/acatalog...2_x_Type_A_to_mini_B__USB_2_0__1m__Lindy.html
tried ebay, my brief search came up with lots of unrelated results, so i gave up
I got one of those leads, came with my portable 2.5" hard drive. Just tried the lead on my Tytn 2 and it does charge almost as fast as the mains plug
Success
Ok, so, I tried to experiment.
Here you go.
Usb simple cable 480ma charge.
The same result with Motorola charger.
Motorola charger pins A and B short circuit - 890mA.
That's much better, althrough I suppose it can suck more current then 890mA, but it's significantly better.
THere is also pins data+ and data- short circuited (I don't know if it has effect, but I can't disconnect it in this connector).
Apparently NC (not connected) pin on our pinout schematics definitely is connected.
With % of charged battery it suck less and less current....I suppose it's usual, this should be even driven by ROM.
So, update your cables
It works even with car charger, so no more charger problems...
Shef
Just to be clear - you took a Motorola USB cable and shorted pins A and B (which are which by the way?) and it provides a decent current....
How do you short the pins? I've looked in the end of cable and I can hardly see the pins, let alone short them! What's the trick here or have I missed something?
Thanks,
Gary.

Also interested in how to short the pins. I use Navizon, bluetooth HSDPA tethering, and iGuidance while on the ambulance and even my iGo 3A max rated charger can barely keep up because the tilt wont accept all of the available current.
So have anyone found a way to fast charge our ppc through usb??
Yes, that is correct. Short pins 4 & 5 (4 is normally NC) to enable fast-charging. If you do it correctly, the phone shouldn't pick up tethering, and therefore should not say "PC Connected" or the like..
The TracyAndMatt pinout is wrongly numbered. The pin assignments are correct, but the number/letter scheme they used is incorrect. True ExtUSB pinout translation to their pinout is as follows:
T & M Real ExtUSB
-------------------------------
Pins E D C B A = 1 2 3 4 5
Pins 1 2 3 4 5 6 = 6 7 8 9 10 11
The way I remember is that the corner opposite the angled one is where pin 1 starts (where E is on the T&M pinout) - and they go like most IEC-standard connectors, in a clock-like circular numbering scheme.
Here's a better pinout: http://pinouts.ru/PDA/htc_extUSB_pinout.shtml
Hope this helps!

its the milliamps that is the problem even doubling up with a y splitter does not do much Find a charger with the most milliamps for a faster charge 1.2 amps works best and as far as i know no usb port puts out that much even if they are wired in a series. Many try to sell lower amp chargers they dont even know about it at att. if the screen is off they will charge but not well these phones are energy hogs. I must have at least twenty chargers and messed around with them... the original or one of highest amperage works for me.

There can be no recommended maximum mAh. There can only be a required current, which differs from device to device. Check Ohm's Law. The device determines how much current it draws. If the charger cannot deliver that current, then the charging process can fail in various ways, all undesirable.

I don't know, but probably not. Apple used to use a different signalling scheme involving resistors.
I got an aftermarket charger in my area since original ones were not available. It says on the label though it's for Galaxy Tab but the max amp is 2100mA min 150mA and the usual 5volts. Is it safe to use even if the original one says 2000A?

Yes,where did u get it,I need one
Just some cell phone shop in my area. My original question was I was asking if it's safe to use even if it has higher amps.
Sent from my GT-P1000 using XDA Premium App
technically, its ok to charge at a higher amperage, it would just entail that you would be able to charge it faster.
but there might be a risk of overheating the battery during charging and that might lead to problems in the long run.
on the other hand, 100mA wouldn't be much of a difference.
It will be perfectly fine. The units charging circuitry will only use as much current it requires, heck you could charge it from a 10Amp 5volt supply with no troubles. I have used in the past an old pc power supply rigged up to some usb sockets to charge various usb devices without any trouble. They are capable of supplying upwards of 20amp @ 5volt.
Btw, i am a qualified electronics technician of 12years experience, i have experimented a LOT.
@baskarz thanks for clearing everything up baskarz.
@prinzhernan could you post a pic of what the charger looks like? thanks

2A chargers will work with the SGT, but you need an adapter like these that I bought.
http://cgi.ebay.com/USB-car-wall-ch...ccessories&hash=item2c5c07736b#ht_3085wt_1163
Reason is the ones that says "For Galaxy Tab" chargers have resistors soldered to the usb port allowing the SGT to know it's connected to an AC adapter and to pull the full amount of power it needs. The adapters have the resistors in them allowing u to use any cheap charger. It allows you to charge with a standard computer/laptop usb port as well. I think it's supposed to charge faster than the trickle charge you get without the adapter but I have yet to try it out. There's another thread that goes into way more detail about it and even how to solder your own resisters to make your own adapters. Think it was this one: http://forum.xda-developers.com/showthread.php?t=845844&highlight=usb+charge
you can charge anywhere were there is a USB port. Just make this.
http://forum.xda-developers.com/showthread.php?t=845844&page=3
that tells your galaxy tab to DRAW POWER from the USB port thinking it is the supplied CHARGER. you can use ANY USB port or charger with this.

Hi Ricey
Correcto, my post can help anyone who wants a 2nd charger to be permanent in office or etc
And most importantly not buy the regular 2A without the resistors inside.
Awesome. Sounds great.
I bought what i thought were a couple higher quality universal chargers. They charge my razr fast but won't charge my nexus 7 at all. I have one of the chargers pulled apart but before I do any soldering I want to make sure -- if I cross the 2 data points will it work?
Well I couldn't wait 10 minutes so I tried. Answer: no. Wtf?
Can anyone tell me how to hack these chargers to make them work? Is there a resistor I need to remove?
Isn't it more likely to be a software thing?
With my samsung Tab 7.7 i couldn't charge it using my ipad charger until a Dev modded the software on the tablet.
are they 2Amp chargers? most universal chargers are only 1Amp
Well whatever the problem is, I want to charge my tablet in more than one place, I want to charge it faster than the 16 hours generic chargers are taking, and I don't want to pay $30 for OEM chargers.
If your tablet is taking 16 hours to fully charge, return it. I can drain mine after heavy use of the day and its still fully charged in under 6 hours.
Sent from my Nexus 7 using xda app-developers app
@soldeus: There's nothing wrong with my tablet. The OEM charger works fine and some of my generic chargers work, they just don't have the current. (See below)
@vivan: They are 1A chargers, but they should still work. They don't charge at all. The 500ma Blackberry charger I'm using here at work will charge it in about 8 hours.
Ironically the move to almost-universal micro usb chargers has made the market for them even worse. Now, instead of having to buy a new charger every time you buy a new phone, you have to buy a dozen different chargers till you find one that actually works. Like I said, I didn't try to cheap out. I got a high quality charger.

The OEM charger is 2A for a reason. Because the tablet uses more power, it needs more current to charge at a fast pace.
Your generic 1A chargers are probably just enough to keep the tablet powered on, without draining (or charging) the battery.
If you can find a 2A universal charger, it should work just like the OEM one.

No, my 1A chargers are doing NOTHING at all. I plug it in and the charging icon doesn't come on. Reviews have tested these chargers at about 950ma and as I said, my 500ma Blackberry charger isn't too bad.. It's not lack of power, it's something else.
My guess is it has whatever resistor it needs to make it an "ipad" charger. And the vast majority of 2A chargers will, too.
So.. back to my original question: what do I need to do to make this charger charge my tablet? I KNOW it's possible. I just need to find the guy who can tell me how.
I also need a charger for my car, my usb power adapter in the car does not work, need to know what car charger will work as this tablet is supposed to be my car stereo replacement, sucks having to bring your stereo in to charge it and hope it lasts till you get done work
I bought the Scosche dual 10 Watt car charger, isn't here yet though. It does say it wont charge the Samsung tablets, maybe due to the proprietary cord because apparently there is a cord that works with them. It's not a specific ipad charger and does say it works with Android devices and tablets.
On a side note, what's the best way to determine what your N7 is actually charging at?
Both of my generic chargers won't work either, a 2.1A generic iPad charger, and a 1A standard USB charger. Considering it WILL charge off a 500ma USB port, it's not a current/amperage issue, it's a software/proprietary hardware issue.

I won't say 100% but I would bet the probability is very high. For the 1A charging they all seemed to play the same game with the voltage on the data lines. Not sure you'll get 2A but you'll at least get 1A.

Hi guys!
I recently switched from a Samsung galaxy s5 to a nexus 6. It's been more than great, really. Why did I ever buy galaxy phones?!
I'm confused over quick charge 2.0 and compatibility with other chargers and couldn't find any proper information on the subject.
At the moment I own:
- Aukey 5-port 35W Charger
- Tecknet 6-port 50W Charger
- Anker Astro E5 15000mAh battery bank with 2A + 1A ports
- Large assortment of other single port chargers @ 2-2.4A from Samsung, ASUS, and several aftermarket brands.
All of these chargers, and the battery, delivered (tested with the Ampere app and tons of different cables) ~2A to the galaxy but only deliver ~1A to the nexus 6. The Motorola turbo charger obviously works as intended. Now my questions:
- Does quick charge 2.0 limit any non compatible chargers to 1 amp?
- Is there a way to mod chargers to at least get back 2A charging?
- Worst case, does anyone have experience with a recommendable battery bank and multi port chargers that support quick charge 2.0?
Thanks!

Why would you need options relating to change charge speeds? Qualcomm quick charger works on any kernel, if you're talking about USB fast charging, it's already enabled in Franco kernel.
There isn't a need to switch to other kernels.

Laptop USB ports at limited to 500mah output unless its a dedicated charging port with USB 3.0 then It can push 1.6A so I don't see how that's possible to charge at 2A from a laptop.
@Pilz this is irrelevant. My 2014 macbook pro charges my old phone much faster than the nexus 6.
Refer to the original post for the topic at hand
Quickcharge 2.0 devices uses the data pin on usb to determine if the charger connected is a quickcharge 2.0 charger. The devices you are using do not have this capability so they charge slower. I do not think this can be changed kernel or phone side.

I could be wrong S5 I looked up uses usb3.0 right? Does your macbook have usb3.0? If so then the usb 3.0 port can supply more current when detected being a usb3.0 device by your computer and ever more so it is possible for the mac to output a little more current. Can you plug in the S5 then open system profiler to look at USB device tree to see current being delivered? The nexus 6 only using usb2.0 would not get the same treatment by the comp and only receive the max standard of .5 A.
There are many details about the actual max current that can be supplied by the computer's ubs port that I don't know when they are applicable I've just stated reading so I'm not sure why you can get 2.0 A on your S5 and not less, since there are standards that set the max current. Even more complicated is that under certain conditions macs have their own heirarchy of supplying more current to some devices if they "say they need" more current and even then there are limitations. So again I'm not sure what is at play exactly, that determines why the S5 gets more than usual. The .5A is normal for current output on USB 2.0 in the nexus6.
I actually got this in the mail yesterday, and the wall chargers works great...Havent have a chance to test out the car one though!

That doesn't make sense which is why I went into some detail about laptop or any computers USB ports. I unfortunately had a MB Pro and hated it, and it never charged any of my phone a at 2A including my wife's old S5. I don't have it anymore so I can't test it again to verify. The person I quoted below explained it a little better than I did.

Those lying bastids! They even stamped Qualcomm 2.0 right on the side lol . Regardless..Wall chargers works as does the car charger, same as the Motorola one

Qualcomm doesn't post every certified charger on their website. In would email the manufacturer and ask for their certification or a picture of it which most will show you assuming on they're legit.

Hi guys!
I recently switched from a Samsung galaxy s5 to a nexus 6. It's been more than great, really. Why did I ever buy galaxy phones?!
I'm confused over quick charge 2.0 and compatibility with other chargers and couldn't find any proper information on the subject.
At the moment I own:
- Aukey 5-port 35W Charger
- Tecknet 6-port 50W Charger
- Anker Astro E5 15000mAh battery bank with 2A + 1A ports
- Large assortment of other single port chargers @ 2-2.4A from Samsung, ASUS, and several aftermarket brands.
All of these chargers, and the battery, delivered (tested with the Ampere app and tons of different cables) ~2A to the galaxy but only deliver ~1A to the nexus 6. The Motorola turbo charger obviously works as intended. Now my questions:
- Does quick charge 2.0 limit any non compatible chargers to 1 amp?
- Is there a way to mod chargers to at least get back 2A charging?
- Worst case, does anyone have experience with a recommendable battery bank and multi port chargers that support quick charge 2.0?
Thanks!

It is technically incorrect for the phone to accept more than 1 amp on a 5v charger. The quick charge *protocol* negotiates a non-standard charge voltage (up to 12 volts!!!). Quick charge is actually BAD FOR YOUR BATTERY! The higher the current, the greater the temperature. The greater the temperature, the lower the battery life.
Unless you *need* it to charge that fast in an emergency, don't.
I've never even plugged in the charger that came with mine, and I don't intend to.

I've used QC 2.0 since I bought my phone during long days and my battery life is just fine. My battery is cooler during QC than when using qi charging so I disagree. Generally speaking you're correct, however the battery would need to get hot and stay hot which is doesn't. QC 2.0 tapers off the voltage and current overtime to a more "normal" amount. Your argument is an old and doesn't always pertain unless your phone is constantly hot.
You're battery degrades overtime anyway and any heat could speed that up. I used to live in AZ where it gets to 120+[°F] in the summer which is hotter than my battery ever gets even using QC from 1% battery. Quick charging won't hurt your battery any more than normally charging it will. There is a cut off for the temperature it will let your battery get before it drops voltage or amperage which will work whether the what is from charging or the environment you are in. As I stated above qi charging will make your battery heat up more (in my case it does) I will post screenshots to back that up if you would like.
Lastly no one is expecting a battery to last 1-2 years without losing capacity so why worry about it? Your phone is warrantied for at least 1 year (I have moto care on top of the regular warranty) which will cover any battery issues. There's no need to panic or make an issue out of nothing.
Now can we please let this argument die? I keep seeing it and its getting rather old. Even if it does (which I'm not saying it does) degrade slightly faster its not a big deal for the aforementioned reasons. Let's get back on topic here people
i researched this for maybe 1-2 hours now and i'm still not sure the answer

[Quick Charge] AUKEY Quick Charge 2.0 16000mAh Portable External Battery Power Bank Fast Charger with Type-C Cable for Samsung Galaxy S7 / S7 Edge and more

looking to maybe get this since it's high capacity and his a type-c cable included (which is whole different problem on its own)
this is what one of the reviews on says the spec is
– Input: DC 5V/2A
– Output 1: DC 5V/2.4A
– Output 2: DC 5V/2.4A, 9V/1.67A, 12V/1.25A

there are video reviews out there with V/A meters that says it will output a 5V at 1.5A to under 2A
the included charger is 5V and 3A which is what's required for 'rapid charging', though i'm reading elsewhere that for whatever reason, the 6p is capable for rapid charging at 1.5A+ while 5x is not
now to add to the confusion, the cable used can affect/damage the usb ports if it's not up to the correct specification (since the 5x will always ask for 3A via the usb-c port <- this i'm not sure of, but that's supposedly where the damage occurs)
this whole usb-c early adoption is making my head hurt, hopefully i can get an answer before the sale ends
is this the USA link to that item? https://www.amazon.com/16000mAh-Portable-Charger-Charge-Samsung/dp/B01B2NWTGG/ref=sr_1_1?ie=UTF8&qid=1469459347&sr=8-1&keywords=AUKEY+Quick+Charge+2.0+16000mAh
I might get one too if anyone knows the answer
I already bought it, I'm just waiting for it to get home. I'll post back when I get it to see how it works.
Ok so I bought it, and it worked GREAT! Fast charges and everything... took around 30 minutes to take it from 50% to 80ish%. It's been a week, I've charged it 5 times already and it's still in the range of 30-90% of battery life. Totally recommend buying this power supply. (I have a Nexus 5X)
Im using this powerbank for 4 mounths and it's really good for my n5x =)
It charged my phone from 5% to 100% in 90 minutes.
