Q: How to know the working times for my device?
A: AC Outlet Working time = 2000Wh* 0.81 / operating power of your device
DC USB Outlet Working time = 2000Wh* 0.85 / operating power of your device
For reference, assuming the power consumption of your device is 30W, working time will be 2000Wh*0.81/30W=54hrs (rough calculated).

A: The voltage of the solar panel is between 18V-48V(18-30V/10A，30-48V/15A), which can be used to charge FFpower 2000W.

If the unit loses power when completely off, try recharging it to 100% and use it to 0% two or three times to calibrate the battery.
