Connect the power adapter to an electrical outlet and insert the plug into the micro-USB socket on the underside of the Camera. Only use the power adapter (5V 1A) with the micro-USB plug. Note: If the Camera is OFF, the LED indicator lights up in red when charging and goes off when the battery is fully charged. It takes about 6 hours to fully charge the battery for the first time. You can continue to take photos or record videos when the Camera is charging. The Camera will issue a voice prompt to warn you that it is powering off when battery is low.
