That’s exactly the same thing that happened to me! I gave my Cube i7 Stylus to my mother and at some point she tripped over the charge cord. It stripped the port off the charge cord so I had to replace that, but the tablet itself refuses to charge. It does recognize that it is plugged in but the battery goes down as if it was not plugged in. As of yet I haven’t gotten around to trying to repair the port but I was going to rip open some devices with the right size of port and see if I can do a frankenstein job on it myself.
