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.

@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 use a verizon branded car charger to charge my N7 but I think they charge $30 for it at the vzw store.
I suggest you read this page as it may have some info to help you modify your charger:

the cost isn't so much the issue, its the actually working part. do they have one with an angled micro usb so i can mount the tablet in the car properly or preferably a usb adapter one where i can use my own cord
For $30 you could order a handful of different ones on ebay or monoprice and find something that works. But I want a dual charger.

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.
Edit... maybe not, see this thread:

I have a philips as351 audio dock that pushes 2A out of the micro-usb charger and the usb port on the back and neither will charge the N7. Bummer because it looks so nice on the dock to
I have numerous chargers at home all of which have charged my evo, gs2, Nexus 7, etc.
Can these be used interchangeable in the Note 2 without harming the charging process?
Thanks
As long as the Voltage is the same (5V) there is no Problem. But you should have a charger at 2 Amper for optimal charging speed.
I just tried charging mine with the normal microUSB charger I use for every other phone I have had and it took 7.5 hours to charge from 5%-62%. I used the stock charger that was in the box and it charged it in 3.5-4 hours no problem. Seems like the charger in the box charges faster.
reading this thread made me curious, my NOTE II should arrive in about a week, I can't tell for myself yet, what is the A (amps) specification mentioned on the original charger?
as i come from HTC, my current chargers go up to 1 A current. witch is the double A a standard USB port will give unless crossover'd .
thanks in advance!

in the wiki thread i found the answer, the supplied charger delivers 5 V 2 A output to the device.

2A! Same as the Tab 10.1 charger.
Filling a 3100mAh battery requires some grunt.
i think even the usb cable makes a difference..
when i use the stock usb cable with the stock charger ..my s3 would charge up comparatively faster than with the other usb cable connected to the same stock charger.:rolleyes

It certainly does! :good:
All electrical cables have some resistance. Very low (but not zero) for quality cables, sometimes quite noticeable for thin and cheap offerings.
From Ohm's Law we know that voltage drop will be proportional to current. A cable with a resistance of just half an ohm will loose about 0.5% at 50mA. That's pretty much nothing. However, at 2000mA the loss reaches 20%.
dude use any charger, just don't use LG charger **** !!!!!
You must use the 5volt 2amp charger and cable provided or a replacement with the same output or youll either be waiting for ever for it to charge or do some damage.
I tryed using my note 1 charger rated at 1amp and guess what? It took about twice as long to charge.

Some of my old 1 Amp chargers aren't happy at all, and will often decide to stop charging randomly.
I though it was something weird with my phone, but after switching chargers it never happened again.

USA official charger
This are the images of the official USA charger that will comes when they release the device in USA
And yes its a 2.0A charger, so the SIII charger isn't appropriate for NoteII.
this is the kind of charger used in Canada, USA, and Latin America, i bought this NoteII in Mexico from an authorized Samsung provider, of course factory unlocked 710usd, like 10,900mxn.
Has anyone tried a 3A charger? Just wondering if this would speed up charging even more than the standard 2A charger.

No, it won't speed it up. It's what the device takes from a charger, and not what a charger can potentially supply. If the device's charging circuit is spec'd for up to 2A current, that's what it will suck out of a charger, not more. You can connect a 30A lab power supply, and it will still be the same 2A (or less) input. To speed up the charging process, you need to mod the charging circuit of the device itself.
I was able to pick up car chargers already, but am having a hard time finding a good deal on extra 2amp wall chargers. Samsung had one on their accessory page for a while, but never got any stock. It disappeared in the last few days.
Might be cheaper to buy an iPad compatible brick and use it with a microusb cable. Works well and charges fast, and reusable for future devices.
radio shack has a 4port 2a that will give max draw to one port. i have already tested it with a multimeter. they are like 22$
Haven't gotten a chance to test these yet: http://www.amazon.com/gp/product/B0073FCPSK/ref=oh_details_o02_s00_i00
I definitely noticed my old htc wall charger is slower to charge the note2 than my nexus 7 wall charger.
Can you guys recommend best car/wall chargers as far as amps(Electrical jargon I'm not too familiar with)?
I was wondering if higher amp is better?
I realize the device will cut off current too high, but wondering what the max it can draw is? perhaps over 2amp?
Will it mess up my wifes Note 1 if she uses my charger? Will it charge hers faster?
no they will limit the charge so you dont have to worry about that. most devices can accept up to 2A at 5V anyways. That is the limit for the spec. The absolute is 2.4 A i think.

You people seriously pay $20++ for wall chargers? LOL!

The joke may be on you if your chargers are cheaply made. It all comes down to the person if they want to stay safe or not. You can risk your battery's life dying earlier than normal, or just plain ol damaging your phone. If you've had luck with those, than more power to you.
If anyone was curious, there was substantial testing done to a few chargers that may give you insight on what to put your money on.

I have seen that one brand of 2A chargers. Do you think it charges as fast as your OEM charger? How long have you had them now?
Also how did you get them for $5 each?
So. My OnePlus 3 just came but sadly the dash charging thingy came with the US style pins. As I live in Germany I can't use the charger right now till I order a european one.
So. For now. Im using a Samsung charger with 5.2 Volt and 2A .. The dash charger has 5V and 4A. Obviously the battery wont charge as fast. But will it damage it in any way? I mean. While the voltage is a bit higher the Amps are lower.
Can I use that charger?

Instead of offering adapters please just answer my question.
I will buy the european version soon anyway. No need for stuff like that.
most charger are a bit above 5.0V as the voltage slightly drop when charging
you can use that charger, it will charge at 1.5A.
It will be better for battery life.
But instead of being rude to nimrodsv, why don't you answer his question, this kind of adapter is a simple yet an effective way to use your charger. When you will have your european charger, you will have 2 working charger, if only you care to buy an adapter.
TurboPower charger that comes with it is the only thing that will give it a fast charge.
I have no idea how or why Quick Charge tech was left out.
Mine does indeed say "TurboPower Connected" and charges super-fast when I use the USB C Quick Charge 3.0 AUKEY Amp Type-C Dual-Port Wall Charger and the USB C Quick Charge 3.0 AUKEY Car Charger with Dual AiPower Ports. I can't seem to find it now, but I remember reading somewhere that the Moto Z does use QC 3.0, otherwise I wouldn't have bought the above products. NOTE: I am going USB-C to USB-C.
Does not use 3.0.
http://forum.xda-developers.com/z-force/help/moto-z-forces-turbopower-quickcharge-t3429607
In short QC 2.0 and 3.0 don't follow usb c spec according to a top Google engineer. According to Usb c spec the vbus voltage should not exceed 5v. QC tech exceeds this by using 9v and 12v to achieve more power. Motorola built the Moto Z according to spec which allows you to ramp up the current (amps) to achieve more power which is why our stock charger outputs at 5.7amps. You don't need QC to charge fast with Usb c. Usb c with power delivery is actually better . Either way the QC chargers put out 15 watts total. Our turbo charger does 28.5 watts using 5v at 5.7 amps and is actually faster than what's out now. QC chargers use higher voltage to achieve this at 9v 1.7 amps 15 watts, a charger doing 5v 3a does the same 15 watts. So to turbo charge your phone don't use QC chargers unless it also outputs at least 5v at 3a that's the key. Anything less than 3a won't turbo charge. It needs to be a usb C to usb C cable so the charger should have a usb C port not a usb a port like most of you are trying to use. No other charger out now does more than 3amps besides the turbo charger until then use chargers that do 5v 3a. Verizon has a fast charger that supports this and all other fast charging tech.

Will these charge as fast as the stock charger out of the box? And with a USB C cable does it need to support quick charge, or do all USB C cables support quick charge as long as you have it plugged into a USB C quick charge adapter like you linked to?
Nothing charges as fast as the stock charger as far as I know.
I looked around on Amazon to try to find a spare charger with the same speed as the OEM, but there are none as far as I know. QC actually goes against usb-c standard, so whoever has a phone that supports both is technically being shorted on charge speed. I will be waiting for the verified brands (ex. Anker/Aukey) to release a legitimate charger because there have been instances where wall chargers have completely destroyed devices. For the fastest charge, you'll want usb-c cables end to end, but since usb-c is not the standard yet, I would be very careful when buying lesser-known usb-c accessories. Z owners will have to wait for the market to catch up at this point.
Total side note but I wonder if the problems Samsung is having is because of their bastardized quick charge/type setup.
I'm happy we don't have QC.

The car charger that Verizon sells turbo charges the phone, but not as quickly as the stock home charger. I don't think any charger will charge as fast as the stock home charger, since it's optimized for the phone. But the Verizon USB-C charger charges the phone plenty fast.

I can confirm this. I just got this phone on an upgrade after insisting to the Verizon sales representative that I did NOT want a Galaxy S8, that I was absolutely sure I didn't want the S8, and that I think the Z Force is a much better device than the S8. After seeing the genuine shock on his face that I slighted his phone, I bought the OtterBox case and the Verizon branded USB-C car charger with it.
The car charger definitely charges faster than my non quick charge USB-C cable, but not as fast as the stock charger. The stock charger will take me from ~5% to full in an hour. The Verizon car charger takes about an hour and twenty minutes to go from ~5% to full.
All in all, it was worth the money spent on the charger. It is definitely better than the 8 hour charge my standard USB-C usually takes.
