So i recently got a kbox 120w and had a problem with the usb charging. It would show it was charging but not actually charging. So they gave me a brand new one with 2 brand new batteries and it did the same thing! Last nite they gave me a kbox 200w and im just wondering if im gonna have the same issue. Has anyone else had these issues? Is this normal? And how long should it take to charge via usb? I charged my 200 over nite and when i woke up the screen showed it still charging but it was fully charged.
