Do I need a special usb plug to allow rapid charging?
I have a usb plug (which I connect the usb cable to from the mobile when charging) and it has an output of 5v.
Will I get rapid charging if I connect the mobile to my laptop?
Thanks
You need a Qualcomm Quick Charge 3.0 wall plug. I bought this exact one (US plug model) in china and it works really well, get's charged from 0 to 100% in 1:30hrs, getting the first 75% between the 0:45 and the 1:00hrs of charge.

Is there a program/driver that will allow the leo to pull more than 500mA when connected via usb? My TP2 (CDMA) has this installed and its bad ass. I can charge faster off things like a cable box (or my computer) than the wall. It pulls ~928mA.
Right now I have a Y adapter.. I plug the power only usb into the computer and the data into an external source (like a duracell powersource mobile). tBattery reads "AC" for charger input. Then, I unplug from the powersource and plug the data part of the usb Y into the computer, hopefully forcing it to switch to usb mode while retaining high current draw. No dice, its still on AC.. and the data cable is not communicating with the computer/phone. If i were to unplug the power only cable, it would probably switch right over to usb mode and WMDC would pop up and all that. But.. I would be limited to 500mA, which is.. really weak since the phone can only use about 150 of that for charging!
Charge with your phone off may help?
That is not possible, because PC can't give more than 500mA on one USB port.
Check in Windows device manager (PC) and find Generic USB Hub. Then look on "Power" tab.

You can't. You could burn USB port in your computer.

This is a screenshot taken from my touch pro 2.. Plugged into the usb port of my laptop. This is possible. It also is possible with my cable box. It requires a driver/app from nuerom..

btw.. ports are either in high power or low power.. 500mA should really say 500mA+... Some ports are NOT capable of doing this.. I'd imagine I could trigger the same by connecting devices to all three of my usb ports on my laptop.
many gigabyte mainboards have the function to deliver 3x more power through usb ports. ive tested myself and can only confirm it is charging within 1.5~ 2 hours completely
Yeah - maybe, but if... higher charging amperage causing battery/phone overheating and dramaticly shorting battery life. I know, that dedicated HTC HD2 charger having 5V and 1A (1000 mA), but this is TRAVEL charger and should be used only in this situation by reasons previously wroted by me. I charge my LEO only with PC.
i think it depends on the charger itself. i bought a docking station and while reading the manual i came across a switch that changes the mode between "charge" and "sync"
this lets your device acknowledge that the charger is capable of providing more mA than a normal USB port so that it can draw more power.
The ac charger (or the battery driver itself) is smart enough to trickle down the charge rate as the battery reaches maximum capacity. We have an aluminum battery cover that seems to have a heat pad to transfer that heat from the battery. The battery driver probably has provisions to stop charging if batt temp reaches a certain #.
500mA charge is not enough. The phone itself is able to draw more current than a 500mA line could provide.
I just plugged a y adapter into my laptop. Plugging only the power portion in. tBattery says USB for charger input.. Taking the data/power 'part' of the Y adapter cable and plugging it into a usb power source (with no data pins, like a duracell powersource mobile) puts the phone into ac charger input. I disconnect the duracell charger and leave only the phone plugged into my y adapter to my computer... still says AC charging.
I'm now able to charge the phone using 1 computer usb port. World doesn't end. Phone doesn't explode.
Pictures are worth a thousand convoluted paragraphs.
Is there a difference between charging with the supplied wall charger and charging using a micro USB cable attached to a desktop or laptop?
Slight difference -- the supplied wall charger charges at 600ma. USB charging from a PC maxes at 450ma so it isn't quite as fast. 3rd party chargers may be detected as USB and cause a slower charge rate too, so watch out for that.
Either way, you'll get charged. USB is definitely slower though.
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?

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.
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

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.
I'm using the usb cable that came with my A52 5G. It rapid charges with the provided wall charger but doesnt charge at all (slow or rapid) with the same cable plugged into a laptop USB port. Is this normal? My old phone at least slow charged off of it.
