Hi. I've had the Nintendo DSI for a while however on the go the charge doesn't last very long. To get past this issue I slightly altered the shape of the end of a USB-B cable which allowed it to fit into the DSI's charging port and the DSI seemed fine as it charged through the cable just as it did with the official charger however is it dangerous to do this or will it be fine regardless of which cable I use?
(The official charger and DSI battery are rated at 4.6v)
