I'm the owner of a Kanger IPOW 2 1600 that will no longer charge. I've dropped it a few times and has had no problems, but now it just won't work. It flashes three times every time I plug it in, without fail, so it's making some kind of connection. It also goes back and forth between giving me a "Battery Full" message and giving me no message whatsoever. It will charge, but only when I hold the charging cord in the port with my hand, applying pressure to the port. As soon as I set down the device, in any position, it stops charging. I've also tried separate charging cords, so the cord isn't the issue. Is there anything I can do to save my battery?
