Power & charging
The Arclight can be charged by the solar panel or USB socket. Full charge is achieved in about 20 minutes via the USB or in a few hours in good sunlight.
If totally discharged connecting via USB for just a few minutes will ‘revive’ it.
A green light is visible when the device is charging (both USB & solar).
Power saving mode
If the Arclight hasn’t been used in a few weeks it will enter power saving mode to protect the battery. This will mean the Arclight will need to be put on charge for a few hours before the next use / to revive the battery.
