A sump pump kicks on in a storm outage, and the Jackery HomePower 3000 answers that with 3,600 W and a 7,200 W surge. The BLUETTI Elite 300 covers the same job with 2,400 W. The EcoFlow DELTA 3 Ultra Plus gives 3,600 W with a 7,200 W surge.
This guide judges the three stations on the makers’ published specs, current in November 2026. PowerPicked Editorial has not run any of the three stations itself.
A watt-hour is how stored energy is counted, written Wh. Watts are the unit of power, written W. AC output is the plug-in power for the basement. Solar input caps how much panel power comes in for a station. Surge is the short burst a motor draws when it starts.

How long does the HomePower 3000 run?
The runtime numbers below assume 85% of the listed capacity. At 85%, the listed 3,072 Wh leaves 2,611.2 Wh usable. A 100 W load draws for about 26.1 hours on that energy. 3,072 Wh over 59.52 lb works out to about 51.6 Wh per pound.
Output is 3,600 W, and surge peaks at 7,200 W. That 120 V 30 A outlet is a TT-30 RV port. UPS switches within 20 ms. A full AC charge takes 2.2 hours. Jackery says it cannot connect extra batteries. Read the HomePower 3000 review.
