Barnes and Nobles ac and auto chargers have special adapters and specail micro usb cords to allow quick charge. They are different then ipad adapters as well.

The auto charger adapter is rated at 5v 2000ma. I think the adapters unlike the ipad adapters have 0 ohms where ipad has 53 ohms. The Barnes and Noble usb cable uses data lines for power and has a longer special micro connecter. If one use a normal micro usb cable with the special auto adapter then we only get 500ma.

Does anyone think using the HP TP cable will work and get more than the 500ma?

Are therea any other auto charger for the TP that will give more than a trickle charge?
