Just got a Tab but I bought it off of someone who couldn't find there charger so I had to find one locally quick and the ONLY store that had it in my area was Verizon but it wasnt a Samsung branded OEM charger, It was a Verizon charger that was suppose to be the same but It doesnt charge via USB and Im wondering if for some reason its not suppose too? It charges USB when the Tab is off but when its on it doesn't? I can only charge it via wall charger when its on? So, is That normal? Or, does the OEM USB charge it while its on and this Verizon one is just messed up? Thanks.
Yeah. I got the Samsung Charger. Charging through USB from a computer is super slow to useless.
Only plugging to a wall provides sufficiently speedy charging.
The Tab is quite greedy for power and using either the USB port on a PC or a low Amp rated Mains USB charger will result in either the phone charging very slowly or not responding whilst under charge.
Charging the Tab using the USB and a PC, well there's nothing you can do about it as the USB standard only distributes 0.5 amps (500 milliamps) of power through each port.
Mains chargers however are rated higher but most common one's only have a Max of 1.0 amp.
What you need is a charger that has the capacity to deliver 2 amps.
Check Google & Ebay, there are a number of chargers available rated at 2 amp.
So usb charging while the tab is on is impossible, right? The charger charges fine plugged into the wall, I just needed to know if it not charging via usb while the tab is on was normal, and from what I get from what your saying is that it is normal, it will not charge usb while the tab is on... thanks.

No, I didn't say it was impossible. I said charging via the USB port on a PC will either be very slow or may not respond whilst under charge, it's certainly not the best method. It's just that with only 500 milliamps of power trickling through the USB port, the second you start to use the Tab in anything that requires a decent amount of power you are not going to get any charge.
The only way I find an ability to charge the Tab under a USB connection when connected to a PC is to let the screen on the Tab turn off and not to touch it. It will still happily communicate with your PC and send/receive data but it will take a much, much longer time to charge that's all.
I gotcha, so...when my tab is on it says not charging in the status but if I let it sleep it actually will just very slow... I understand what your saying and thank u for your time, I just wanted to make sure it wasn't the usb cable I got to know to take it back or not...

I charge mine at night via USB to my computer. Starts around 20% by the time I plug it in. I don't power off the tab. Always has a full charge in the am.
I have a double usb cable that is used to power an external drive. I would need a female to female adapter, but this should provide more power to the GT.

Yes, providing the cable you have charges when using with a mains plug then yes, the cable is good.
If however the cable did not charge even when using it with a mains plug then definately you would have a sync only cable.
Thanks, I'm just gonna let it sit overnight with it on sleep n see what happens

To charge through your PC with official USB cable, you should make your own USB "bridge"as short the data wire while insert an 33K om resister between gcc and data wire, an 10K om resister between gnd and data wire.

Yep... I left it on the usb in sleep and it did charge so the cables fine, It just sucks that it doesnt when the tab screen is on but oh well... If theres any solution to fixing this that it charges well from usb then let me know, I know someone just commented about modding the cable to work but theres gotta be a better solution...
Sounds like u bought a stolen tab. No charger or box?

just used a spare double-headed cable from a portable hdd that fortunately has a full size usb plug on the other end. (Most have mini-usb at the drive end)
I use it with a female-female usb adapter and it works pretty well for the PC, particularly on USB 3.0 ports.
I also saw these on Amazon:
amazon dot com/Apricorn-Power-Adapter-Cable-AUSB-Y/dp/B000JIOHDE
I believe Blackberry do one for the Storm as a standard accessory as well
For the car I got a car charger designed for iPad with a USB socket that delivers up to 2.1A
Belkin has the car charger

(I should say, I don't actually have this one, mine is a generic brand that also has a 1A usb socket)

no need for all that, just plug it in computer USB and wait it take sometime but it charge, because pc USB are not powerful enough to feed 2A to the tab.
If I helped you, please press the thanks button ;-)
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?

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.

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'm about to use a Moto Milestone 1 charger for OB but I'm afraid that it may harm the phone. Both phones are listed with MicroUSB 2. Any tips?
thanks
Don't worry.. it will work Ok, but OB charger has 1000ma, if you use another charger that has let's say 500ma (like USB) it will take 3 hours to charge the phone instead of the regular 45 minutes!
I use a samsung cable directly from USB, the car USB port, a samsung 5530 charger, a LG optimus one charger, and they all worked, with various degrees of effectiveness!
The most useful one is the car's USB port that, even if it cannot keep up with the GPS (it charges slower than the battery drains), it can keep the phone running with 10% loss every hour with screen activated and GPS at the same time! The problem is that I hate radio and don't use CD's that much, and usually end up with the phone depleted before I reach the destination!
Thanks man! Ok I'll check that "ma" thing. BTW is it written on the battery or charger?

Both places; battery specify working and standby V and mA, charger specify the V and mA provider
So you can use almost every different charger if the specs are the same, but be aware of this: don't use a charger with less mA since it can burn the charger
Ma - miliamps.
How many milliamps in 1 watt/volt? The answer is 1000.
I assume you are converting between milliampere and watt/volt.
I never had a burnt charger by the way, that would be very strange considering that the phone is accepting 500ma from the start (that is the USB output on any PC), and I even saw chargers with a power of 2W (SUPER FAST CHARGERS). The Motorola chargers are 850 ma usually, so it should work quite good!
Indeed, it's very strange to have a burnt charger and we don't need to go into an electrical discussion but that happens because of 2 possible things, very high-peak of voltage or prolonged use of under-voltage

Thanks. Printed on my Moto charger is 850mA so I'll rather use it for my OB next time.
BTW, currently I'm using a replacement charger for my OB with a name "super charger" printed "4.5v - 9.5v 800ma"
It's charging at normal duration in fact I'm using it for days. The only problem is that my OB touchscreen freaks out if I use it while that charger is connected. It's obvious when I run the multitouch testing app because touch points run all over the place. Touchscreen goes back to normal if I disconnect the charger. I tested that "super charger" to my milestone and the same abnormal thing happens to the screen. What causes it?
Probably it's something to do with high voltage... I'd avoid using it if something like that happens to my phone..
Usually the USB style chargers are pretty standard... the speed with which they work are strongly related to the power (Amperes) they provide, the voltage "should" be pretty standard!

Battery experts say to try and use a charger that's rated half the power of the battery.
So for a 1500 mAh battery, a charger of 850 mAh should be a better option than a 1000 mAh one.
Yes, the 1000 mAh charger would charge the battery faster than the 850 mAh one but it will decrease the lifetime of the battery faster.
Just for be able to post new thread. Sorry.
Hello, I don't want to start a new thread so I'll ask here.
The charger that came with my OB seems to be damaged. It was working properly until last last night. My phone detects the charger but it won't charge. Got powermax turned on and it automatically turned off when I connected the charger, so I know my charger does have issues.
Tried banging the charger last night, connected it to phone and started charging, woke up to see that it stopped charging 2 hours ago. It didn't even fully charge my phone. Now I'm charging it with my pc via the USB cable. I noticed that the touch screen goes wild when I use it while connected with the USB.
Now, I'm planning to buy a Galaxy S2 charger. Is it safe to use? S2 and OB has almost the same battery capacity so I'm considering it. Any other suggestions? OB ain't popular here in the Philippines so finding accessories is a real pain in the a**.
Fitted a Corby 2 charger and it seems like they use Mini-usb too. Haven't tried charging with it though.
My original charger also died... Now I use the one that came with my bluetooth headset
So I guess using the OB charger on other stuff is okay too. USB is always ~5v.
You need to test the charger with something else to be sure, though.
I had the same touchscreen freaking out problem with my old LG KS20, whenever I charged it. Like it was shorted or something. So it maybe a problem with the phone itself.

Ok kabayan, don't forget to share here the result after u try gs2 charger. I too am looking for safe alternative to my milestone charger.
Standard port - standard voltage
Don't even bother, if it has a micro USB it should be fallowing the same standard as USB for charging (5V)...
Of course test the charger for any adverse side effects like screen flickering or short battery life, and don't use it if something like that occurs, but because of the standardized voltage and the fact that usually phone chargers have between 500 - 1000 mA, 99% of chargers work...
I still haven't found any incompatible charger for my phone and I don't even buy a phone if it has a non standard Charging/Data Port... it's just stupid... so no Iphone for me!

Hello guys! I'm here for an update. For the past week I've been using a Corby 2 charger. And guess what, it works just fine! only downside is it won't charge it up to 100% (usually gets to 99% upon unplugging). And it charges the phone a little slower than the original charger. I always let the phone overcharge overnight to have 100% battery.

FUC* stolen how ? this it`s baaaddd ....
Using CM10.1 (06-14 nightly) on my One (International), connected to a Belkin 1A USB car charger with a decent quality USB cable. The phone discharges slowly in general use, and quickly when using GPS. Looking in battery settings it shows "Charging (AC)", which would suggest that it's drawing the full 1A for charging. I didn't notice this problem on stock Sense, although it's been a while since I used that.
Has anybody else seen anything similar on their One? Is there any useful information I could get from a logcat to give to the CM devs?
Thanks in advance,
Jon
OK I checked on stock and it does drain similarly. Should I just get a more powerful charger or could I have a hardware problem? Tried with 2 different 1A car adaptors.

Have you got a clamp meter or know someone who has one? That will tell you how many amps are going into your phone. It does sound like the charger though as your charger at home should be similar voltage/amps to the car charger only the AC charger needs a transformer and rectifier to step down the voltage and change it from AC to DC, car chargers just step down the voltage a little (12v-5v) so require little additional size. Probably easiest to swap out the charger, they're pretty cheap

It's probably not about the Amp rating of the charger. You probably had a cheap charger unit that couldn't deliver the amperage the phone needed either cos it was using cheap parts or something. A proper 1amp charger will still do as well as your new 3.6A charger

Yeah that makes sense. I just thought that if I got a massively over-specced charger then it would at least manage 1A Would have expected the Belkin one to work properly in the first place but never mind.
