What size power station to run a Oxygen concentrator?

Typical draw: 350W running / 600W starting. Sized below for a 5-hour run — drag the slider for your real runtime. Check your specific model's label; sizes vary. Medical loads deserve extra headroom and a backup plan.

2,300 Wh
Look for ≥2,300Wh capacity, ~350W continuous / 600W surge or better.

Right size: Extra-large (≈3,600Wh) · 3,600W

Typical price $2,000-3,200 · e.g. EcoFlow Delta Pro 3, Bluetti AC300 + B300 module

A fridge and essentials for a day or more, a 120V window AC, a home office through a long outage. Approaching generator money; the value comes from pairing it with solar so it refills each day.

Runs this load ~7.9 h on a full charge.

One size up: Expandable home backup (≈6,000Wh+) · 5,000W

Typical price $3,500-6,000+ · e.g. EcoFlow Delta Pro Ultra, Bluetti AC500 + B300S (stackable)

Backing up whole circuits through a transfer switch; add battery modules for days of autonomy, especially with solar. A home-backup system, not a grab-and-go unit. For 240V loads or true whole-home coverage, compare against a standby generator.

Runs this load ~13 h on a full charge.

Adjust your loadout and runtime

Real setups aren't one appliance. Add loads and set your runtime below — your Oxygen concentrator is pre-checked.

Capacity includes inverter loss (~15%) and a usable-charge margin, so the station isn't run flat. A solar panel or vehicle charge extends runtime past this number.
