FAQ
How long does the Pulsar 5250-Watt Dual Fuel with CO Sentry run on a tank?
The maker rates it at 10 hours at 50 % load (about 2,125 W) on a 4.0-gal tank. A light load such as a refrigerator and lights runs longer; a full load runs shorter.
Can the Pulsar 5250-Watt Dual Fuel with CO Sentry start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 5250 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
