How many watts does a Home Oxygen Concentrator use?
A Home Oxygen Concentrator draws 350 watts continuously once it's running, but its motor needs a brief surge of up to 550 watts to start. A generator has to cover that starting surge, not just the running load, or the motor won't start.
Running it 12 hours/day costs roughly $21.42/month at the U.S. average residential rate (~$0.17/kWh, early 2026, per the EIA) — real rates vary a lot by state and utility. Use your own rate in the House calculator →
