To make use of the camera more convenient, we provide a double-port cigarette-lighter adapter in the product pack. While the adapter is charging the camera, you can still use the other USB socket for your another electronic device. However, please plug the charging cable of the camera in the socket closest to the blue light.
When the adapter is plugged into a cigarette-lighter, make sure the blue light is on. Otherwise, plug in the adapter again and push it to the end of the cigarette-lighter. The adapter will charge the camera only when the blue light is on.
