I do not take any credit for this work and am not responsible for any damage if anyone tries this. I have a usb battery and wanted a way to charge my tablet with it. After searching the internet I found this website that tells how to splice a usb cable with a power plug for our tablet. Here is the site: USB charging cable for Coby Kyros | Showing My Geek I have done it and it was pretty easy to do. It has worked to charge my tablet and so far has not damaged it. The power output on our factory charger is 5v 2amp. The one on my usb battery is 5v 1.6amp. Pretty close. I have also tested the cable on a usb power plug that is 5v .7 amp and it still charges it. Like I stated If you try this I am not responsible for any damages.
