I have the perfect tablet ?

I’ve been trying to find a tablet to bundle with my 3D PotterBot (www. 3DPotter.com ) printer. I’m starting to have a nice collection of cheap tablets that are almost acceptable. My latest purchase which I thought was going to meet my expectations after Mathias recommended that it should have 1 GB of RAM. But to my surprise there is no DC charging port.

I thought maybe there was a cable that could do DC charging at the same time while it is in use with the printer or power up the Arduino mega 2560 USB PORT WITH 5 V ?

It looks good but I don’t like to buy something without any reviews and also the brand is unknown. Maybe a couple of guys in the shop in China putting this together?
