Took the USB cable out to my car this morning and plugged it into my Stanley power adapter combo unit which has a USB port and Prime didn't even recognize being plugged in what gives?
The adapter needs to output 2.1A for the prime to charge while its on, try turning it off and plugging it in to see if the charge light shows up

Hello
As you know, our device doesnt get charged by the USB cable it comes with (or veeeeeery slow).
As I have a solar charging device with USB slots, I need a compatible USB cable. Somehow it has to work, is there some converter or something ?
Thanks!

Eh? My device charges just fine with the included cable.
You will have trouble charging it from a solar powered USB charger as I'm guessing it will only put out 5V at maybe 500mA. That's not enough to juice the TF. It's not the cable though.
Because ASUS used a USB connector on its cable, unfortunately does *not* mean this USB connector 100% follows the specifications for USB.
It has a trick, whereby, when connecting to your PC it works like USB at 5v. But, when connecting to a 15v charger it switches to use 15v instead.
The TF charging indicator, and Android OS battery settings, only indicate charging when 15v applied. At 5v it may trickle charge with screen & wifi & ??? turned OFF. I never try charging at 5v because it is too slow.
LOL
I don't think it charges at all at 5v?
EDIT:
How can I delete a post?

It will, provided you have the amperage. But its only trickle so its only really charging with the screen off and charges slower than the tablet uses battery.
I have noticed the NT only charges when using the AC charger and not when connected to a PC like phones. It even has to use the cable it came with as normal micro usb cables do not work (not for charging anway). Is this right or is this posdibly a hidden setting somewhere I have missed?

The computer does not provide enough amps to charge it. The first day I got mine I plugged the usb into a phone wall charger and it indicated it was charging but didnt seem to be increasing charge. I left it overnight and when I woke up i checked the charge...it didnt budge. I looked at the two wall chargers. The phone charger is a 1 amp charger while the nook charger is 1.9amp. Considering a usb from the computer only provides .5 amps there is no way it will charge.
This is the same as the nookcolor. They use the same charger and have the same limitations.

In addition to the current difference, the cable that comes with the NC or NT has a different MicroUSB end. It is a little longer to reach the higher current pins. There are several discussions in the NC Accessories forum that go into the details.
The NC can charge via pc, as long as the usb hub is powered, or the usb ports are powered, with the provided cable micro usb cable.
Other tablets can charge over .5amp USB so it should work on the NT unless they intentionally designed it to be limited. The Lenovo ThinkPad tablet and iPad both worked via .5amp USB. Just very slowly (had to put iPad in sleep mode).
EDIT: iPad 1 for clarification, never owned the second.

I have a newer motherboard (Gigabyte Z68XP-UD4)
when I plug my Nook Tablet into the front USB, it doesn't charge. But I just plugged it in at about 80% power into the rear USB that was red and labelled "3x USB Power" and it charged WHILE I was transferring files.
I didn't know it was charging until I plugged it into the AC and it showed 100%.
I can confirm it with video evidence if you need it because I'm not one to spread misinformation.
My Giga X58A-UD7 will charge mine too. The option must be enabled in The BIOS in order for the additional Amps to be dispensed. And, it will only work on the onboard (rear) USB ports.
Am I correct in thinking that the USB Standard must include a provision for optional high power pins that may not be present in all USB cables - or chargers?
If I have a standard microUSB cable, can I use my 3x port to charge my NT or do I need to use the special longer connector cable that came with the NT?
Another poster said the Nook USB connector was actually longer, so the high power pins would reach the recessed ones.
Bottom line - don't assume just any cable will work.
Are thenook color and tablet chargers the same? im looking to pick up a spare on ebay,
It's the same thing as the ipad. It will say not charging but it actually does just reaaaaaaaaaaally slow.

They appear to be the same or at least work the same. I have one charger downstairs and one upstairs and the tablet and color charge fine on either one. Just make sure to use the B&N cable, unless you want to wait a while.
So does anybody know where we can pick up chargers cheap? I already have like 5 micro usb chargers and it sucks I cant use them.
AFAIK the NT and NC use the same power supply. My NC with CM 7.1 draws about 600-700 milliamps (according to the Battery Monitor Widget). I have successfully charged it from a PC using a standard micro USB cable. Here's the catch:
- when you connect the tablet to the charger it will turn on. Power down the tablet completely. It will then charge, but takes about 12 hours.
From what I read in the manual, USB charging should work for the tablet, but not the dock? When I have USB plugged in (to either a PC or an ipad charger) there is no indication of charging (but USB connected shows in system Panel)
Is this normal?
That's normal for the original Transformer and does agree with the Prime manual the way I interpret it.
Are you trying a USB 2.0 or USB 3.0 port? It may charge from a USB 3.0 port, which is what the charger's USB port is. I've never tried charging from a USB 3.0 port, in spite of actually having a new PC here with one.
My charging setup is to have the ASUS charger plugged in to a power strip, I then have a six foot USB 3.0 cable extension, then the standard short ASUS USB 3.0 to 40-pin tablet cable. This works great.
Bye.

mine will not charge from just USB either I have to use the power brick that came with it.
ok, I hadn't realised the port was usb3. Makes sense, even if it is a little annoying to have to always have the charger (like if I want to charge in the car)
Are there any car chargers that would work with the Prime?

I am sure there probably is but I just use a inverter thingy that gives you a regular plug outlet I will link you the one I have it's really nice has a USB port too

I'm trying to reduce how many cables and plugs I use. Currently I charge my phone via micro usb, and was wondering if there is an accessory I can buy that will connect from my micro usb cable and into the Prime's proprietary port so I can charge my phone and tablet of a single plug (my phone overnight and then my tablet the next day). I'd much rather have a small adaptor sitting on my bedside table for when I need it than yet another wire trailing across the floor. My plug socket is tucked behind my bed so simply swapping the usb cable each time isn't really do-able.
Many thanks

it is do-able if you used a male to female usb adapter. Then you could just plug in the cable you need to charge with.
I have not seen a micro female usb to full size male? I have seen full size to micro.
You could always get a powered USB hub aswell and have both plugged in. I though I read somewhere that the prime charges best when plugged into the wall though.
I'm going to guess your phone charges at ~5v and the prime will want ~12v (link) ...
There are some reports that 5v will "charge" a transformer, but I'm skeptical ...
More than likely 5v would be more of a trickle charge at a slower rate.
@Tomlilley What did you end up doing?
@copc Interesting idea regarding the powered USB hub. Would the following configuration be possible: TF plugged into a power USB hub and charging, an external HD plugged into the power USB hub with the TF accessing the external HD?
Doesn't USB max out at 5v and Prime is 15v by default (it looks like it charges at 12v as well).
First off, I'm not some dumbass who doesn't know that the USB cable has to be in a wall jack to charge the NT. I'm just curious as to why this cable only charges with a wall jack and not when it's plugged into a computer...
Because
Well it does not give out enough power from the computer.
so it does not charge quickly.
But if you plug the cable in to your computer and the nook while leaving it on overnight, it should charge.
so it does charge, but just really slowly
(click dem thanks buttons)
Helps to turn the screen off too.

Wall charger is 2000ma most PC USB are 500ma max.
I don't think the 500mA limit is the whole story. My Nook won't charge off of other 2A USB charger I have nor with any other cable (even if using the Nook charger).

You need the stock cable to charge at the higher rate with compatible 2A chargers. Compatible chargers will have the data pins shorted. I've found that my HTC HD2's charger will actually charge my NT at the higher current as long as I use the NT's stock cable.
