my Chinese tablet computer blew its battery (literally, although I do admit that I dropped it first) and I could not find a replacement anywhere, nor could any specialists help, so I decided to upgrade and fix it myself. Bought a 20.000mAh external battery with a 19V output and made a new, much improved housing, including 2fans to cool things down (it is after all running with an i3 chip), basic inclination for working the touchscreen and a steep inclination for watching movies. It now also has 2 stable handles (one thing I don’t like about tablets in general is the fact that there is nothing really to hold on to) and at the same time a good wide base to sit on a table or one’s lap.
you may put on some wheels also to maki it “portable” 😛
thought about it, but then remembered that I can easily carry it around in my electric scooter.
