Error code F7

We sincerely apologise for any inconvenience caused. Please review the troubleshooting steps below.

If the “F7” error appears during solar charging:
Regarding the lighting conditions when the F7 error occurs:
• Was it sunny or overcast at the time?
• Is there any shading on the solar panel?
• Are you attempting to charge behind a window or glass surface?

If sunlight is weak, the input voltage may fall below the required level, triggering the “F7” error and preventing charging. Once sufficient sunlight returns, charging will automatically resume — please rest assured. For best results, place the unit outdoors in full, unobstructed sunlight.

If the error appears to be temporary:
If none of the above apply, the issue may be a transient fault. Try resetting the portable power station using the following steps, then check whether the issue has resolved:
Press and hold both the Power and USB buttons simultaneously for 5 seconds. The display will briefly turn off and then relight, showing the battery percentage and other status information — this confirms the reset is complete.
