FAQ
How long will the EcoFlow DELTA 3 Ultra Plus run a refrigerator?

Can the EcoFlow DELTA 3 Ultra Plus start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 7200 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
