Charge your device with the included Type-C charging cable: The device is compatible with standard 5V USB chargers. It takes about 4~6 hours to get the battery fully charged with 5V/2A chargers and about 12 hours with 5V/1A chargers.

Charge your device with a solar panel: If the place your device is installed can get enough sunlight, it is recommended to install a solar panel for your device. To use the solar panel, go to the device's Settings > Power Management, and change the Power Source to Solar Panel. After that, the status LED of the device will not turn Blue, but you can identify the charging status from the Noorio app. Remember to change the Power Source to Battery if the Solar Panel is no longer in use.
