I have just bought up my transformer ( Love it ) but it's at about 10% battery right now... I take the cable that came with it (the usb one) and plugged it into my computer but it is not charging ? Any idea what's wrong with it ? when i plug it into the charging unit it works fine though
i've heard it has to be turned off for the USB charging to work....
Like off as in screen off or off as in complete off ?
It will not charge in your computer. You have to charge it in the wall.

One of the pamphlets that came with it said the screen has to be off in order to charge it using a computer's USB port, cause the screen uses too much power and a USB port doesn't output as much, its best just to charge with the ac adapter. Nothing is wrong with your unit, thats just how it works.

Turn off the screen and it will charge. (you don't need to turn it off; you just need a black screen) It is very, very slow though.
My wall charger never charged my tablet so I am awaiting a replacement. The USB charge is MUCH slower than the wall charge. We are talking about maybe 4-5% an hour -- max with the USB cable alone.
Connecting this thing to a computer will NOT charge it. Even a normal 5V 1.2A-2A charger won't charge it fast enough. I used a 2A charger and it trickle-charged for over half a day and managed to clock in @ 50pc. I think the unit uses hardware info from the ASUS charger to detect the charger. Any other charger wont do.
Isn't the cable and charger USB 3 and charging is at non USB 2 values (voltage and current).
Good amount of mis-info in this thread...
The unit *will* charge from computer USB, assuming the USB port provides enough amperage (not voltage). I have not yet measured out the amps used, but it's on my list of things to do...
In order to charge from computer USB, the display on the Transformer needs to be off. The unit can be on, but it must be asleep.
The adapter that comes with the transformer provides 15VDC via extra pins which loosely resemble USB 3.0. These are *not* USB 3.0 data/power specs, however a USB 3.0 extension cord could be used to lengthen the existing adapter.
Any USB car adapter should work to charge this in sleep mode, similar to a computer USB port. In order to "fast charge" in a car, however, you'd basically need to use an AC inverter with an ASUS Transformer adapter.

Tried a 2.1A 5V charger. Took about 8 hours to charge @ 50pc. The ASUS charger is rated at 1.2A.
is the only way to plug the device into your PC or laptop via USB on the dock?
you cant use the proprietary charger cable to do USB data transfer with the charging cable USB component?
ie....to do data transfers via USB (not the memory card), the only way is via the dock?

No, one end of the charging cable is regular USB and the other end (tablet-end) is proprietary. You can transfer files over by connecting to your computer's USB.
awesome, thanks.
do you think that if you get a male/female USB converter, you could plug in a USB memory stick device or a mini hard drive device and have it work fine in the charging cable just like you would if you were to plug in a mini hard drive into one of the usb ports on the dock?
When I connect my P6200 using usb, it doesn't charge, instead, there is an 'x' symbol at the battery. Is this normal? Because using my Galaxy Ace, it charges when usb is connected. I'm asking this because I'm trying usb tether for the first time, but in this case if it doesn't charge, it means that I can only usb tether until my battery has depleted and I would have to recharge again to be able to tether.
Yup. Usb is not able to charge tab and ipad. Need to plug to wall for charging

Actually it does charge. More of a trickle charge tho. If the screen is off, then it will trickle charge a bit faster.
If the tab is connected via USB, will it at least be able to sustain itself via the USB power?
So if your battery is on 50%, and you keep the tablet on and are using it. Will it at least stay on 50% and not decrease slowly?
Samsung puts a resistor in their chargers so the tablet can distinguish between a Samsung brand charger and all other chargers.
The tablet will not charge (or use power from) any USB port except the wall adapter. (lame Samsung... really lame...)
You can buy adapters (or make them)
There's more info for creating an adapter yourself in this thread http://forum.xda-developers.com/showthread.php?t=845844
Just like the GT-P1000, P6200 is charging over the usb port of any pc, only when it is turned off. But anyway the charging process is much longer. Very useful when you don't heave the travel adapter with you.
i use this usb cable it work
It pulls a Max of 500mA from the USB or unknown charger. This will charge a tab plus with the screen off that isn't doing much. It will pull 1500mA from the Samsung wall charger.

My Plus charges normally from PC via USB. Icon shows 'x', but still in charging process anyway. It takes longer time but for those who tether should be ok and Plus should stay at least on the same level of %. I have unoriginal cable bought together with car charger.
I purchased a micro USB charger adapter from ebay. It just plugs into the 30 pin port and I am able to use my cell phone charger with no problem at all. The cell charger puts out 1000ma and the tab plus recognizes it. Do a search for P6200 Micro USB Charger Adapter on ebay.
If you are determined to use a computer to charge the tab plus, you will need the adapter above and a dual USB A to micro USB B Y cable. It will plug into two USB ports on the computer and give you the 1000ma to charge the tab plus. This is the best solution without having power cables all over your desk.
re
HEllo, where can I buy this cable?
thanks

i just got this adapter from dealextreme for the p1000. it works perfectly fine for the p6200. i got my 2.1A charger to work and can charge of via USB port.
Thanks

or you can make it charge by requesting this feature in a custom kernel
Thanks
Yesterday I bought P6200 without charger, was using usb cable and it ws slow.
First I thought there might be some problems but this post helped me figure the cause
Hi all.
Could the charger of desire work normally(when check in about phone it must be show AC not USB) for the HTC desire HD and Inspire 4g.
Thanks
If it shows AC that means you are charging through a power outlet and when it's charging by USB you are charging it through a USB cable connected to a computer
Charging through AC is faster then USB

Why does USB from PC charges slower than the one from the socket?

PC has only 500mA current output, your wall charger has 1A output
greater current faster charging-but this does not mean that battery has not its max. charging current!
higher charging current can easily damage your battery and cell phone.
I charge my phone with Xperia charger, with Kindle charger, with Nokia charger and many more. So far I have no problem with my battery. As long as on the end of the cable you have “micro-b usb” and stable (troublefree) electric transformator to supply that cable you can charge your battery. The time to charge may be different but the result is the same.

+1 you only have to use a micro usb!
The charger should work with any phone other than iPhones

Correct!
As long as it is a usb micro charger, it all works....
only the time required to fully charged varies...
I am using a Nokia USB cable as a Charge. Works fine too.

As long as the two data cables are connected to eachother, the DHD will recognise it as a wall charger, and it will use 1 ampère. Instead of the 0.5 amps when connected to a PC (when the data cables aren't connected to eachother).
You can buy "charging only" cables. They always charge at maximum rate and do not transmit any data. Usually come with external battery packs etc.
Just to clarify some. (Talking about USB2.0 as 3.0 has a little higher power)
The USB on computers are powered by the motherboard (if not using extra PCI USB card).
Usually the motherboard gives about 500mAh to each USB host. If that host has 4 USB connectors all those connectors share the 500mAh.
And just be careful to not go above 500mAh as some (older) motherboards or even add in card's cannot handle the extra power and will fail to work(permanently).
So a charge-only cable will not make a difference in this situation, same goes for using multiple USB ports as that also brings extra problems with it, as power/voltage doesn't flow in just 1 direction (when using 2 poles). You could blow out USB voltage regulators when connecting different USB power leads together.
As for the phone side you can also use a 5000mAh power source, as the phone will 'take' what it needs. For DHD the max charging power is about 800mAh~900mAh if I'm not mistaken.
As long as its 5V and somewhat stable.
So if you want to charge the DHD (or any other USB chargeable phone, mostly all of them) as fast as possible use the original wall charger.
If you have to do it on the PC/Notebook unplug as much USB devices as possible, so most of the power can go to the phone.
Also make sure the screen of the phone is turned off as that's the biggest battery drain of the DHD. Thus also making charging slower (when on).
I'm using htc charger to charge my e-cigarette . It's works good.
If you plug it into USB socket, and enable "Fast charge" option, does it do anything? Does it block the data transfer and acts like a wall socket (1A) ?
Is it possible to obtain a USB cable for fast charging, i.e. more than 500mAh without modding?
See for example:
S107 S105 USB Charger Charging Cable For Mini RC Helicopter Syma S105/S107 2A
I'm asking because a lot of USB chargers in the range of 1000-2000mAh come with either no USB cable or a standard USB data cable that limits charging to 500mAh.
I have an Android Box plugged into the screen in my car. It's running an Android Auto receiver. So I can plug my phone into the box, using a USB-C to USB-A cable, and Android auto works. Now I have a fully functional android auto, with one problem. The phone is charging at less than 500 mA. Does anyone know of a cable that could possible charge the phone with a car charger at the same time it's plugged into the box?

You are mistaken here. The cable does not limit the charge that goes through the phone. The limit that you are seeing on your phone is due to the USB port that you are using which has a max output of 0.5Amps.

Correct, but I need to stay connected to that usb port for data so I thought there might be a cable that had two USB-A ports on it. One for data and one for power.
greeting,
I bought a Nexus 6p and looking a charger (for car and EU wall charger).
I'm interested in whether it is compatible with QC and QC 2.0 3.0?
He prayed to the recommendation.
For Nexus 6P charging and date sync, the Type-c to Type-c cable is better than USB-A to type-c cable.
