To charge your Magma hoverboard, first ensure that you have plugged your charger into a working wall outlet; the light on the charger will illuminate green or blue. Next, plug the other end of the charger into the charging port on your device. When connected, the charging light will illuminate red and turn green or blue again once charging is complete. Be sure to only charge your hoverboard for up to 3 hours or until the light changes from red to green or blue - not longer. Overcharging or undercharging will affect your battery and is not covered under warranty.
