FAQ
How long does the A-iPower GXS1500i run on a tank?
The maker rates it at 6 hours at 50 % load (about 600 W) on a 0.7-gal tank. A light load such as a refrigerator and lights runs longer; a full load runs shorter.
Can the A-iPower GXS1500i start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 1500 W peak. That is below a typical 1/2 HP sump pump start (about 2150 W); check your pump label. Use the calculator with your exact pump.
