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.

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:

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

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.

Hey guys
Have got the GPS working properly on my SGS (props to those who figured that out) but I've noticed something a little concerning.
When I'm running google navigation that battery continues to run down, even when its plugged into my car charger. It'll survive for a good few hours, but it seems a bit bad to arrive at wherever I'm going and need to borrow a mains charger when I get there.
Anyways, I'm normally running bluetooth to my jabra speakerphone/fm transmitter, but nothing else that should agitate the battery too much, and with GPS turned off, it happily charges even with the screen perma-lit.
Im running stock JG5, and my dash charger consists of a cigarette lighter to USB converter and the stock USB cable.
Any thoughts on whats up with this would be greatly appreciated!
The phone is probably consuming more power then the 500 mah charger can provide. You need a dedicated mini usb for charging, the ones that actually are usb cables only provide half power

I know once people get the proper pinout's ...sites like fommy or cellphoneshop will have them for like 4.99 or cheaper...
i love my tab..but for christ sake...where are all the friggen accessories?...*sigh*
You'll definitely need a real cable, and a charger capable of 2Amp output, or it probably won't charge properly.
I'm using a 1 amp charger from my Garminfone and it works fine (60% to full charge in 1.5hrs)
I also tried a 2 amp Iluv usb charger but it went into usb mode (pc connection mode) and did not seem to charge??
Cable and accessories are expensive!! I bought a data/charge cable from Aliexpress for $6.50. Should have it in about a week. Will let you know if it works. Paid with Paypal so I'm protected.

When i connect my tab to a usb-hub with 3,8amp it does not charge at all, it even continues to discharge. the hub is a 7port belkin with a 3,8amp power supply.

That's because when you plug it into a computer, it negotiates for power with the usb controller. You can see how much power it is getting by looking in the device manager under the usb hub. Most devices can only get 500 mA from a computer usb port.
Sent from my galaxy tab
Its not a computer, its a external belkin 7-port usb-hub with a 3,8amp power-supply.
No computer is connected.
A hub shouldn't really supply power at all without a computer connected to it, it probably defaults to whatever the lowest power setting is. Just because a hub uses a 3.2A power cable doesn't mean every single usb port will have that, it's sharing that power with all of them.
No its not the hub, its the samsung charger thats wired differently.
I just modified a usb-extension cable and now the tab charges from my hub and my laptop.
The changes you need to make to the cable have already been described here.
http://forum.xda-developers.com/showthread.php?p=9355551
Also, you dont need 2A.
The samsung charger is charging with 1,5A only because it has 5,4V.
With 5V you will have only 1amp, so no need to buy a 2A charger/battery.
And yes it just jumped up 1% charging from my laptops's usb port while the tab was running.

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?

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.

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.

I won't charge mine via the USB port..takes too long. Top off, is ok. Complete charge...no way. The N7 has a big battery, so I use the AC charger. 5 hours via USB (dead battery ???) doesn't sound too long to me. Most USB devices only charge at some low rate...like 500 milliamps. You should be using, at least, twice that.

If you look at your Asus supplied Nexus charger you'll see that it's rated at 2A the N7 will happily draw all of that to charge. A pc or laptop usb2 port can supply a maximum of 500mA, that's only a quarter of what the N7 needs to charge at decent rate and you can damage the usb port by putting too high a load on it. My advice is to charge your N7 via the mains charger and forget trying to use the usb port, get a second charger or a portable battery pack if you need to charge while away from home (see the thread on battery packs in this forum for details)
For reference a usb3 port can output 1A if it's set up to do it.
According to Tom's hardware you are still quick. Their graph says 0-100% on usb, screen off 10 hours.

Hmm. Maybe there's something up with my tablet then. I found a YouTube video for the tab 10.1 that showed to plug the USB cord in just slightly to where it makes a connection to charge, but isn't fully inserted to make the data connection. This trick is working for me with the USB PC connection and car charger. It makes me think there should be a way to change a setting or something to always make it charge when plugged in.
