I've noticed when I have my tablet plugged into my computer via USB it doesn't appear to be charging. The battery icon is showing a red lightning bolt. This is different than when I have my tab plugged into a wall socket.
Working as intended or..?
Your PC USB port can't supply enough juice (500ma max) compare to your wall socket (>2000ma) to charge while power the tab. Turn the tab off and your will get some charge off the USB port.

It's been charging my tab for about a month now with no problems at all, but I'm not here to argue, if you feel that you know more than I do. I've charged the tablet using that adapter from my laptop, PC, and Energizer XP4001 Power Pack.
You might also search the forums, as I'm not the only one to recommend and use this item.
USB Charger
Have also use this USB charger Adapter Cable For Samsung GALAXY Tab p1000. Works great.
currently having thea similiar,but not same problem; bought this cable of of amazon http://www.amazon.com/gp/product/B005EAEQR4 and while icon indicates its charging, % is not going up at all, mayb 1% per hour or so... am ready to return it, but want to know if anyone else is experiencing similiar problems with a longer cable?

Ahh thanks! Was wondering why it wouldn't charge via my USB port.
(In fact using my Samsung Focus USB adapter for the outlet doesn't seem to work either... I need to use only the Samsung Tab USB adapter)

The focus charger is rated only about 700ma (same exact one as Captivate/SGS), marginablly better than PC USB. GT 10.1 has a rather large battery and hence it requires much larger charge current. You don't see any laptop get charged via USB, do you?

Is that through the orginal AC adapter or through PC USB?
Turning off the tablet and charging it via USB works, but it takes forever!

And you are not the only one who is waiting twice as long before his tab is fully charged. Then we can open a topic "Why does it take so long before my tab is charged?" As foxbat stated: You don't see any laptop get charged via USB, do you?
So if I say your adapter doesn't work its just as accurate as your answer it does work.

Hey, I'm not here to argue with you. I'm just an idiot.
Go about your business, and don't listen. I'm ok with that.
First of all, not all USB ports are equal.
On many modern PCs, the USB ports can deliver more than 500mA over USB if required. This is definitely true for pretty much all Macs since 2007, and quite a few mainboards from other manufacturers (see this article for some background).
Secondly, I've had one of these adaptors for quite a while now, and have used it regularly to charge my Galaxy Tab 7" which uses exactly the same power supply and cables as the GT 10.1. I can categorically state that when using this adaptor, it the GT7 does charge from a Macbook Air and a 5000mAh external battery that has a 1A output USB port labelled for an iPad.
Whilst it might not be as quick as the wall charger, it is definitely much faster than attempting to charge the GT7 from the same devices without the adaptor, even if the device is in use.
I've not formally tried to charge my GT10.1 with it yet, but I did check to see if the "not-charging" indicator went away (which it did), so I rather presume it will work much like the GT7.
Regards,
Dave

You don't need to embarrass yourself by saying you're an idiot, It's very childish and the second time you mention I'm supposed to be smarter then you. I'm sorry you take this so personally.
i just use the supplied cable and it charges via usb on my computer. it shows not charging, but it basically trickle charges when the tab is both on and off
Hi, everybody.
i just buy a samsung galaxy tab 7.7 and just noticed only can be charged by using the power socket provided by samsung.
now i found a way to charge your tab by your laptop or PC through samsung STANDARD USB DATA CABLE cable.
First, download the software (ASUS Ai Charger) attached:
Second, just install and enjoy to charge your tablet through use cable.
FYI, battery indicator still showing no charging but actually it is charging.
you can check after one minute by viwing the remaining power up.
Thanks.
Is this software just raise yr usb port mah to certain amount?
If so, will this harm the computer?

My tab charges when plugged into my computer without that (or any similar software, only Kies and AOSP USB drivers installed). It doesn't show charging but the charge definitely goes up. Does that software actually make it charge faster? I have to say, I'm pretty dubious.
I would recommended getting the following adapter, I originally bought it for my original tab and was able to charge via the laptop with no problem. It charges as fast as the wall charger.

my tablet is charged well.
Thanks
Thanks for the info.
Though it must be noted that you need an Asus motherboard for this, my Gigabyte provides 1A front USB ports thats where I charge the Tab7.7 I'll try if there is any difference real world difference if I plug it into one of the regular USB ports.
I accidentally found out I was able to charge from my Mac without using this special software as follow:
I bought an external battery, New Trent IMP99D (Amazon Link) and it came with a special USB extension cable (picture below) that is designed for the Tab 10.1. If I plug the GT7+ directly to the IMP99D without using the extension cable, NO charging takes place. However, if I use the extension cable, charging works.
I connect the extension cable to my MacBook Air, connect the GT7+ charging cable and the tablet and... VOILA.. it's charging! HoneyComb even reported that it is an "AC Charging" and it charge pretty fast.
So you can either
a). Buy the battery and it comes with the cable
b). Buy JUST THE CABLE, model IMP44B (manufacturer link here)

I've ordered thus one. will see uf will charge the 6800 with the 30pin cable to computer usb...
If you just want to charge via pc you can turn off your device, this way will work.

I recharge the battery using my pc all the time... just connect it with the USB cable and that's it... no software or anything like that... The tablet battery Icon does have a strange X on it but it still charges the phone (AHHuummm, Tablet) just like the electric plug thingy...
I'd like to use a USB flash drive on this.
The "charge port" is a standard micro-usb, so any micro-usb to usb adapter will work.
You will need a USB-OTG (on the go) cable, its like 5 bucks. But you need to make sure that the mini usb has enough voltage to power the devices. My vote is that it does, because the users manual talks about excessive power drain from heavy consuming devices.
Hi All,
I have an issue with my Galaxy S4 (CM12.1) and the Leicke Clever Dock multimedia and otg dock I'm using. If I operate the dock by the instructions (plug in usb peripherals then plug in HDMI then plug in micro usb power before plugging the phone in) it works flawlessly. If I then power off the dock leaving the phone on (i use macrodroid to set it into a low power mode) and then power up again it starts charging but wont transfer the screen to hdmi unless I pull out the phone and plug it back in.
I assume that the issue is the trigger for MHL but I cant understand whether it is something in the phone that isnt putting the usb port into mhl mode or if its the dock not doing something.
A few options:
1 - Find a new dock that enables this (im struggling to work out whether any of them can, even the official samsung one)
2 - Get the phone to enable MHL when charging (i have searched high and low and cant find anything that might be able to help
3 - Get the phone to disable and then enable the usb port (dont know if this will even solve the problem)
4 - Other (suggestions appreciated)
Im also investigating screen casting and will see if there is a route there but I will also need the OTG capability.
Cheers

Hello guys,
Does anyone knows if there is a otg cable/hub that can power the tablet and be able to use data like usb connected at the same time?
Thanks
The 2019 tablet does not need this, since the port is USB type C albeit USB 2.0; I have connected mine to a hub and have pass-through charging and data. OTG is not really a thing any more since USB type C came about.

Can you share the type of hub you have been used?
Is the charging speed fine?
Kingston Nucleum. This tablet is in my car and the hub receives power from a 12-14v converter providing USB C PD and USB 3.0 fast charge. Ultimately, the hub defaults charging voltage to that of the lowest device connected. In my case a Sandisk SSD and a Meizu HiFi DAC Pro. This generally means that charging is slow, however it depends on your configuration. I'd say that the charging speed is fine, however it only charges when the car is running or in accessory mode and the tablet is always on in that state. As such the excess power it uses to charge whilst running is only a little more than it uses. It might charge faster if I power the hub from the USB C PD port, however I don't know if this is just pure amps or whether it negotiates higher charging voltages. I don't know if the Nucleum hub allows negotiation of higher charging voltages.

Nice, i'm using for the same purpose.
In my dash car
I'm also using MacroDroid for automation.
My issue right now is how should i leave the tablet when i turn ignition off.
I Think i will just shut it down, but i don't like to wait 30 seconds to but again when i turn it on.
What do you do in your case?
I'll have to check out MacroDroid. I'm currently set up with AutoMate, however there's a few annoyances which I think need ironing out. Vanilla Android Auto might not be the most exciting, but it's certainly the most friendly for driving safety.
I leave my tablet as-is. AutoMate automatically wakes the tablet into car mode on USB power and goes to sleep when it loses that. My car (Chrysler 300C) has accessory power for 30s (I think I can increase this in the EVIC) after the ignition is turned off which keeps the charger energised, and by extension the tablet. I'm not too bothered about having to boot up the tablet if it does discharge its battery to shutdown. I think it's maybe a week or so for it to do that, likely less when the tablet ages. As long as it charges and runs on the supply happily I think we're good. In that instance, I might have to see whether an auxiliary power bank would be a workable option. Not at this stage though. Bear in mind that most modern car head units still take about the same amount of time to boot as an Android tablet anyway.
I'm having minor USB issues myself, however this is down to the cable I need not being available. A lot of USB C "charging" cables are only pinned for power and not data. This might be part of any USB C issues you might be having. I myself need a USB C male with a tight 90° or 180° turn, out to a USB C female for the hub's pigtail. I might have to make the choice to fabricobble myself a USB cable just for this purpose....
This is a photo of the install, prior to me wrapping it in 3M brushed black steel vinyl.
I'm updating all of my comments in various threads on this. My setup with the Kingston Nucleum hubis having minor issues. The tablet still needs to be powered up before I turn on the car or at least supply power to the hub. It seems that if this is done the other way around, that is, to power on the car accessories (and hence the hub) then it seems to end up staying as the "device in charge" of the USB network. The tablet charges (slowly) but doesn't mount the USB SSD drive or the USB DAC. If the tablet is powering the hub (in charge, so to speak) then applying power to the hub via the car accessory supply has it working as expected. This does mean that the tablet ends up with a power drain when the car/USB power supply is powered down which isn't ideal. I've gotten into the habit of turning the tablet off when I park for long periods of time, however I need to boot it up to "take charge" of the USB hub network before I can start the car. It's a bit of a bummer.
I'm unsure whether this is a tablet hardware/software issue, the hub or whatever. Going into Android settings and trying to alter the default USB behaviour returns the message that it "cannot switch roles" or something along those lines. I'm beginning to think that this might be the USB hub refusing to switch/relinquish power supply roles once it has external power and hence not allowing the tablet to mount drives or see connected USB devices. It's weird behaviour, because you'd imagine that if the hub were connected to a laptop this would be a common action.
If it helps, I've read that OTG function is not included by Samsung for their device's USB ports. I've been trying to connect some together to perform file transfers with no success. However, I have been able to transfer and charge simultaneously between my SM-T510 tablet and PCs with the USB configuration set to file transfer.
