Hello, I just got my Samsung ETA-U90EWE charger (US plug) from eBay and when I use it to charge my Note 2 it shows that it delivers 1698mAh of current into the phone. However, when I use the ETA-U90UWE (UK plug) that comes with the phone, it also displays the same input current, but with the UK one, it charges much faster. What is the problem?
Note: In both cases, I use the same USB cable which came with the phone and both charger delivers the same 2A current at 5V.
Thanks.

will the included USB cable that comes with the Note be able to charge the phone in my car if i plug it into lets say my iPhone auto adapter which has a usb port on it?

You will be charged at much slower rate (limited to 500ma max), or not at all if your phone battery is almost dead. iPhone chargers are designed for iPhone only. You will need a Samsung auto charger (some other non-iPhone smartphone chargers may work too, just not iPhone chargers).
I just bought a cheap 5$ car charger USB adapter for the note will it work?

It will definitely work. The question with those cheap ones is, how long will it last. I usually try to find an OEM branded one like this:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250973439590#ht_2859wt_1000
Typically, chargers with USB port on it will only do slow charge. In order to support fast charge, you will need short out the data pins to allow phone to draw more than 500ma. Typically auto-chargers that comes with microUSB plug directly, such as the Samsung auto charger, will do so, asume your charger is rated to output more than 500ma.

It will be able to charge it. Keep in mind IF your iPhone USB charger max current output (5V 1000mA) is LESS than the Note's charger output, it will take longer to fully charge - but it will charge and will NOT damage the phone.
If you're looking to buy a new usb charger, look for one with the highest mA output rating since whatever device you plug into it will only draw what it needs. ie, my iPad charger is rated @ 2A/2000mA so it covers every device I own (all rated for different current inputs from 500mA up to 2000mA) and that's the only usb charger I take when I travel since I just have to switch out cables to charge other devices. On the other hand, if I only had a lower current rating usb charger, my iPad (requires 2000mA) would be out of luck.
Current output info can be found on the respective charger of your favorite device.
Hope that helps.
it does help, thanx Rand! i cancelled my Amazon order...wish i saw this post sooner.
I have this works great with anything up to 2.1amps...

Looks like that charger is rated @ 700mA. It'll charge the note about 30% slower than the wall charger.
This is my car charger

Hi,
I've read some threads here about charging the S3, but not all is clear to me. I would appreciate some explanation:
1) I've read that the stock chargers output 1A. However, on the charger I got with my S3 it's written "output: 5V 0.7A". So do you think I somehow got a wrong charger?
2) I want to buy a car charger for the S3. There are many generic car chargers in ebay, some of then output 2A current. What is the maximum current allowed for the S3? I couldn't find this number in my S3 manual or on the phone itself. Will a charger of 2A cause harm to my phone? or to the battery? or to both?
Thanks in advance!
bump... does anyone know?
My charger output states .05v=1.0a.
As for what aftermarket charger to buy, I would stay away from chargers with more output than the official for 'peace of mind that my charger's specifications are the same as the official charger that came with the phone' reasons.
Cheers
Generally wall chargers output 1000mA (1A) and USB ports 500mA (0.5A)
You do not want to purchase anything that goes above 1000mA

I attach a picture of the adapter I got with my S3.
It says 0.7A on it, while it appears that other have one with 1A.
Did they con me with this adapter?
And regarding the maximum current allowed: do you think an adapter of 1.2A might harm the S3?
Do not know where your S3 come from but this charger is not made For S3 but for S2!
I just checked the model number:
S3 charger: ETAOU81EBE
S2 charger: ETAOU10EBE (like yours)
And there is no cable on the S3 charger, it use the USB cable
Thank you for this!
I don't get it. The charger was inside the S3 box and looked original. Damn!
I think the store I bought from import their S3 from Germany, since it came with Vodafone German stock ROM. Is it possible that this is the charger they sell on German vodafon? Or perhaps the store switched it for some reason?
Mine also come from my carrier: french vodafone
Was your S3 box sealed?

Hi,
Background - I am an electronic engineer and have designed power supplies.
The Amp rating on a power supply is it's maximum capability to deliver power. The Voltage is the 'force' that it can push electrons through the device, this is the important one to have correct. So a 5V 300A Power supply will not charge your S3 any quicker than a 5V 1A power supply.
Get yourself a 1A car charger and you'll be fine. Depending on how the data pins on that charger are configured it'll be recognised as either a fast or slow charger but it will be fine in any case.
So, according to what you say, there should be not problem to use a 5V 2A charger on the S3?
The charger cannot accidentally push too much current to the device?
No. The phone limits the Amp the battery can get.
It simply won't go above 0.5 or 1Amp depending on what resistor is coded between the data pins (the 2 middle pins on the normal USB-plug)
(Note that this does not extend to all devices. E.g. cheap chinese toys and their batteries may not have any current limter, connecting them to "too powerful" chargers will result in damages or potential blow-up of the battery. The same applies to batteries without any electronic such as car batteries which can overheat and "cook")
I bought S3 in Germany 1.0A, there is a date on the charger:18.05.2012

Hi burmo,
An interesting concept. I have no clue in these things but what you say is not clear to me "all the way".
Charging my i93100 phone with 5.0V 3.1A will do no harm because it won't "push" more than 1A anyway?
And who is "responsible" for controlling this "push" the charger/battery/phone?
Does it work the same for Car chargers?
Thanks a lot,
Izik

so i have been wondering about this as well because i am currently building a custom charger for my s3 that charges the battery without having to plug into the charging port. i have redirected wires from the wireless charging port to metal tabs i have place on the back of my phone. it is a "drop in charger".
Anyway i have tested the charger that came with my phone. I also have the samsung stock charger that say the output is .7amp but after testing it with mutimeter, i have found that the output is actually 1.2 amps. As for max charging amps, I am not sure. I have tested several chargers. The new S4 charger puts out 2.34amps and i have not found any problem charging my s3 with it.

As far as I know the phone limits it so as you've found yes you will be fine
My original S3 charger is 5v 1.0amp
My original S3 charger is 5v 1.0amp. It was bought in Thailand with the phone.
I agree with burmo an advanced phone will have a current limiter as part of its circuit, however I prefer not to rely on it and not to exceed the manufacturer volt/amp recommendation.
The phone controls the current. In custom kernels (Boeffla and so on) you can change the target current. The phone has a protection built in, if the voltage is unstable (drops to much) it lowers the current untill the voltage is stable.
A HTC One charger I sometimes use (0,7A rated) only delivers 0,8A. A aftermarket charger I own (1,0A rated) is fine delivering 1,2A (modified target current, not stock). These charging currents can be read by various apps.
Get yourself a 1,0A rated charger and speed up your charging time.

Seconded the post above being an electronic engineer as wel.
Voltage should be exactly the same as you need, but this will always be the case for a USB charger.
Current should just be enough or more.
The charging current is dictated my your phone and not - and I repeat - NOT by your charger!
mine rates at 1A
I got the Pisen USB to 2A converter from Hong Kong. It cost about $2 USD shipped.
I have no idea why it works, it's charging my P6800 at 1% every few minutes with stock cable. Without the 2A converter, it has the "not charging" symbol.
I tried the same cable with TouchPad and iPad chargers and it has the "not charging" symbol.
However, this converter doesn't charge my Galaxy Note as stock charge do.

It simply has a capacitor that ups the amperage. Use at your own risk, though. I had something similar for my OG Samsung 7" Tab, and I'm pretty sure it caused damage to the battery.
It does not have anything magic inside. It have only the two resistors connected between VCC/USB/GND to fool the tablet is connected to original charger. So, with this adapter you must be sure you can sink 2A from the usb port. On my research with my Tab 7 Plus I've found that the maximum current is below 1.5 A. So, if your USB port provide this current than you can use it. It puts the tablet in fast charging mode.

Wow... If I were you, I wouldn't comment on stuff I had no idea about.
Can the charger bundled with the Galaxy S4 'fast charge' other phones, or is it something to do with the phones/batteries themselves that allow the quick charging? I heard that the charger charges at 2amp as opposed to 1amp like most chargers. I dont want to explode someones phone battery because it cant handle being charged that fast, lol

Using a 2A charger on an older phone won't hurt the phone. The phone will only draw 1A or however much current it's setup for, even if the charger is capable of delivering more.
Other devices will pull the full 2A from the charger if they can detect that the charger is of the right type to deliver it. Different chargers tell the device that in different ways. Apparently, Apple tablet chargers put a certain voltage across the data pins. Samsung high current chargers supposedly put a different voltage across the data pins. That is how the phone or tablet can tell what kind of charger it's connected to, so they will know whether to pull 2A, 1A, or 500mA (or whatever).
Hi. Mobile operator in Poland sales moto e without charger. Can somebody tell me exactly what parameters has original charger?
It's sold without charger to be inexpensive. Any micro-usb charger should do. You can use USB cable to plug in and charge it without dedicated charger. I use charger from Samsung Omnia II i8000 with 5.0V ~ 0.7A.
