I brought a re-branded Chinese tablets. It's no Nexus, but it's pretty good for the price and it does what I need it to do. The packaging it says that it supports recharging through a USB mini socket (The USB port is specifically labeled as being for both peripherals and charging on the box). Only, when I plugged it in, it wouldn't recharge. At first I thought that it might be faulty (see above about it being a rebranded Chinese tablet) but then I noticed that the mains adapter is 12v, not the usual 5v that you tend to see, which means that my PC probably doesn't output sufficient power to recharge the tablet. I'd like to buy a spare mains adapter, is there such a thing as a 12v mains adapter that has a UK 3 pin plug on one end, and a USB Micro plug on the other. I've already checked the manufacturer's website, and they don't do one? Also, is there any way to get my PC to output 12v over USB, for example, a powered USB hub with a special high powered socket for recharging things?
