FAQ

How long will the EcoFlow DELTA Pro 3 run a refrigerator?

About 77 hours for a typical 120 W refrigerator that runs 35 % of the time, after inverter and depth-of-discharge losses.

Can the EcoFlow DELTA Pro 3 start a sump pump or well pump?

Starting surge matters more than running watts: this unit is rated 8000 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
