FAQ

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

About 39 hours for a typical 120 W refrigerator that runs 35 % of the time, after inverter and depth-of-discharge losses.

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

Starting surge matters more than running watts: this unit is rated 3400 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
