Error code F7

We sincerely apologise for any inconvenience caused. Could you please refer to the troubleshooting guide below?

F7 Error Occurring During Solar Charging
Sunlight Conditions When the F7 Error Appears
– Was it sunny or cloudy at the time?
– Is there any shading on the solar panel?
– Was the unit being charged through a window or glass surface?

The F7 error may appear when sunlight is insufficient, resulting in inadequate voltage for charging. Once sufficient sunlight is restored, charging will automatically resume — please rest assured. For optimal performance, we recommend charging outdoors in a clear, unobstructed location under direct sunlight.

Recovery Method for Temporary Errors
If none of the above apply, the issue may be a temporary fault. Please try resetting your portable power station using the following procedure:
– Pro Series: Press and hold both the DISPLAY and USB buttons simultaneously for 10 seconds.
The display will briefly show “8888”, then return to normal operation — the reset is now complete.
