FAQ
How long will the Grecell 500W Portable Power Station run a refrigerator?
About 10 hours for a typical 120 W refrigerator that runs 35 % of the time, after inverter and depth-of-discharge losses.
Can the Grecell 500W Portable Power Station start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 1000 W peak. That is below a typical 1/2 HP sump pump start (about 2150 W); check your pump label. Use the calculator with your exact pump.
