I have had my kbox70 for about 7 months and love it however I have run into a small problem. When charging it never reaches full it just keeps on charging even after 9 hours using different usb chargers and cables. It does not heat up or get warm and I dont think it's over charging. Anybody know if this is a common issue on the Kbox70. I am thinking of buying a new one but am worried it might do the same . Shame as it's a cracking bit of kit when fully working.
