I'm not sure if it will because I know for a fact that the USB AC adapter that ships with the iPad 2 does not work with the Samsung USB cable for charging (well, it kinda does, but its that slow trickle charge). I figure that the means that both companies use to get the extra juice flowing over the USB cable are different somehow.

It is. You can get a charging adapter off of DealExtreme, or make one yourself (read the "make your own cables" thread in Accessories, and look at the Universal Charging schematic)
I have a cigarette lighter USB adapter that kicks out 1500 mAhs, and it's enough to charge the Tab 10.1. Since this thing has more than that on tap, it's a fairly safe bet that it will be able to charge it as well.
..
thanks for the info guys. I did order charging adapter cable from dealextreme. I'm going to order this external battery pack and see. Should i get the 5000mAh or the 11000mAh?
Not sure if anyone else is looking for a spare wall charger like I was or not, but I found one on eBay that looked the same as the OEM one, and I bought 2 of them so I could have one somewhere else at home, and also have one to carry with me when travelling. If anyone is interested, the seller was accesscables and the item I bought specifically is here. They arrived yesterday and both work for charging. They look like Chinese knock-offs as they have the same information printed on them as the original charger.
I've tested some of not original chargers, all they works fine.
There is 5V 2A output on original samsung charger, but to make charge it must have output from 0,85 to 2 Ampers (and 5 volts, of course).
This one from DX (sku: 48615 with european plug) works just fine, it has 5V 1A.
The ideal is 5V 2A - it make charge faster.
Would this charge fine on an iPhone charger, or a universal car charger?
I am currently using THIS for my mobile and tab ，really light smart
As this may be off topic, but what I did was is I went to walmart and bought http://www.walmart.com/ip/RCA-WPW2UWR-RCA-Wall-Plate-with-2-USB-Charging-Outlets-White/20976676 . Now I just take my charger that came with me as the spare
i am using the HP touchpad charger, i think HP was selling them for 5 dollar shipped
http://www.shopping.hp.com/en_US/ho...er-Supplies/FB341AA?HP-TouchPad-Power-Charger
i gives enough juice to charge the GTab
edit (no more free shipping now)
Nice find. When I sold my first gtab I kept the charger just to charge my phone with. Glad I did. Didn't know they were $20.
I use my iPhone & iPad USB chargers. Also a belkin mini surfer protector.

I use an Apple USB charger for travel, works without any problems for me. Only disadvantage is that its charging woth just 1Amper.

Can I use the charger for Asus Transformer 101?
I'm asking this because i just tried a non-branded chinese external battery that has 1A output and it says "MTP initialization" when i plugged the tab..
Any idea which brand works for galaxy tab?
Your battery should work, but you need to buy something like this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130690906449#ht_1611wt_715, to force it to charge.
The ext batt that you have could work if yr tab is shutdown/switched off. You could use the adapter mentioned above, but... your ext batt output is 1A, the adapter increases the std USB current of 500mA to 2A, I wouldn't.
The 1A current is not the rated current for our charger. Its 2A, if you look at the charger really carefully.
If you use the ext battery while using the tab, my guess is it will drain both the ext & int battery at the same time. Or trickle charge when idle... (not sure on that).
Hope it help...

Thanks, the ext battery actually has 2 outputs, 500mA and 1A,
so i can use that adaptor,
but i prefer to use the smaller output for my blackberry..
I'll see if i can find 1A to 2A adaptor..
If I'm not mistaken the normal output for smartphone chargers are 1A, (iphones/ipods, HTCs, samsungs). Not sure abt BB, never use one. U shud check the supplied charger for the current rating. U get 500mA when you connect to a pc usb port, so charges at slower rate.
You can't just create more current with an adapter like that (unless you reduce the voltage, but that wouldn't help anyway).
I suspect that all those adapters are doing is shorting the data pins, which is what is done on most wall chargers. This makes the device think it's plugged into a charger instead of a computer.
I'd probably make my own adapter, but if you don't want to or want it to look a little nicer that should work fine. It won't charge at the same speed as with the wall charger though.
This one works even just straight cable
Im really suprise my old Callpod FuelTank Duo (500mA per port)works perfectly charging my Galaxy Tabs (gTab 7.7 P6800, gTab 8.9 LTE and gTab 10.1 4G)
http://www.geardiary.com/2009/11/16/the-callpod-fueltank-duo-rechargeable-dual-device-power-revie/
But the latest DreamGEAR i.Sound Portable Power Max 16,000 mAh Backup Battery (2.1 Amps on any single port at a time ) which I recently bought doesn't. why? But the i.Sound can charge a more power hungry iPad3 easy.
http://www.ilounge.com/index.php/re...-portable-power-max-16000-mah-backup-battery/
Im really confuse now and still wont be able to let go of my vintage FuelTank Duo because of this reason.

I just ordered this and will try. I also found this one and ordered one also, hopefully this will solve the charging issues using a external battery power pack

Yes that adapter is what i needed to use to get my Mypal/Energizer 18000mAh to work w/ my 7.7.
This adapter is no longer available, can someone post a link for this item pls?
I have a Mophie Juice Pack that charges up my 7.7 (and most other devices) just fine.
http://www.amazon.com/Mophie-Powerstation-4000mAh-External-BlackBerry/dp/B005OW4BFE/ref=pd_sim_e_2
The 7.7 seems to be problem in this regard. This one doesn't work either
http://club.dx.com/reviews/text/53689
Which is very odd as it works fine with my Dell Streak, in itself a difficult phone to find an external battery pack for.
I hope we get sufficient contributors so we can build a database on this.
i'm using Yaobao Powerbank 11200mah... work quite fine... link just showing the product...
http://www.imcc.com.my/store/products.php?product=Yoobao-Power-Bank-11200mAh-Portable-Power-Charger
beware that there is a fake product similar to this...
I have just finished testing a generic Zagg type item similar to this
http://dx.com/p/ac-rechargeable-600...er-w-2-usb-output-for-iphone-psp-black-129067
The top outlet designated "Optimised Charge" doesn't work but the lower outlet designated "General" does. Albeit very slowly, 1% every 20 minutes.
This is not an external battery that I would recommend in any event. It self depletes from 100% to zero in 7 days just sitting in a bag waiting to be used.

If edan1979 says it works with the 7.7 then that will be good enough for me to get one. Awesome capacity too.
yup its the same one... can recharge 2 times... but i'm using it with my other device... working well..
From what I could find, it seems that Yoobao have upgraded the Powerbank 11200mAh to the Thunder Powerbank YB-651 13,000mAh.
I have just bought a YB-651 13000mAh from Maikai UK.
There are two charging outlets, the one that works for my 7.7 Tab is USB 1 DC5v-1A and this charges at a similar speed to the Samsung wall adapter.
The other outlet USB 2 DC5v-1.5A - designated for iPhone, iPad and Tablet PC - doesn't appear to be compatible.
It is a funny old game this, why do some battery packs work with the Tab 7.7 but not others.
Just bought momax ipower pro for galaxy tab.comes with 5v 2 amp and 5v 1 amp outlets.
Also came with 2 micro usb cables and a galaxy tab to micro usb adapter..
2 Amp out let works great....
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
Since I got my note 3 I've been charging it with my old AC chargers I bought on ebay which is a generic micro-usb charger (I got a couple of them laying around the appartment). I use my old chargers often because the samsung USB cable which was provided with the phone is always pluged into my desktop computer, and I didn't want to go trough the hassle of moving the cable all around the house to charge my phone.
Well anyway, so far I've notice charging times were pretty long(6-8hours), but I shrugged it off because I simply thought a bigger battery require longer to charge. But this weekend I slept off at my in-laws and I brought my samsung cable and AC adapter. I looked up with better battery stats and notice the charge time was around 3times as fast. (2hours or so for a 100% charge). Dammmn!
So why am I getting long charges with my ebay chargers?
Is it because they are cheap china product?
Is it because they don't have the USB3.0 port?
I'm thinking the USB3.0 has nothing to do with charging times if it's pluged with an AC adapter right? So my long charge time must be because of cheap products? Ok then, but if I want to buy additional chargers, or even a cradle for my bedside table. How can I know if they will have the best charge time? Am I forced to buy samsung branded stuff just to make sure?
Cause I'd be interested in something like this :

but I'm not gonna buy it if it takes double/triple charging time..

The Note 3 should charge in just over two hours with either USB 2 or 3 cables. If you download https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free&hl=en that will tell you the charging current. It should be 1200mA with the screen on and 1800mA with it off (trick is turn the screen off for 10s then back on and refresh and you should see 1800mA).
As long as the charger can deliver 1800mA and you are using a decent quality cable that should be all you need. Plugged into a USB port you'll only see 450mA on either USB 2 or 3.
Usually the ones that charge this quickly have an output of 2 amps. That is the output of the charger that came with the phone.
