Can an EcoFlow DELTA Pro run a sump pump (1/3 hp)?
The sump pump (1/3 hp) draws about 800 W running, with a 1,500 W startup surge; the DELTA Pro delivers 3,600 W continuous and 7,200 W surge. Its 3,600 Wh battery runs one for about 20 h.
Continuous: 3,600 W ≥ 800 W needed → ok
Surge: 7,200 W ≥ 1,500 W needed → ok
Runtime: 3,600 Wh × 90% ÷ 160 W avg = ~20 h

Common questions
Can the EcoFlow DELTA Pro run a sump pump (1/3 hp)?
Yes. A sump pump (1/3 hp) draws about 800 W with a 1,500 W startup surge, and the EcoFlow DELTA Pro delivers 3,600 W continuously with a 7,200 W surge rating — comfortably enough. On its 3,600 Wh battery it runs one for roughly 20 h (the load cycles ~20% of the time, so it lasts longer than raw watts suggest).
