What size power station to run a CPAP machine?

Typical draw: 60W running. Sized below for a 10-hour run — drag the slider for your real runtime. With humidifier off. Heated humidifiers add 100-300W. For medical devices, verify against your unit's label and keep backup battery capacity.

Look for ≥800Wh capacity, ~60W continuous / 60W surge or better.

Right size: Midsize (≈1,000Wh) · 1,800W

Typical price $500-900 · e.g. EcoFlow Delta 2, Bluetti AC180, Jackery Explorer 1000 v2

A full-size refrigerator through a multi-hour outage, a CPAP for several nights, tools in short bursts. The popular sweet spot. Recharges fast and takes solar input, but still time-limited on heavy loads.

Runs this load ~13 h on a full charge.

One size up: Large (≈2,000Wh) · 2,400W

Typical price $1,200-1,900 · e.g. EcoFlow Delta 2 Max, Bluetti AC200L, Jackery Explorer 2000 Plus

A fridge plus several small loads for most of a day, a window AC in short stretches, longer off-grid stays. Heavy to carry but still one-person portable; the point where solar recharge really matters for multi-day use.

Runs this load ~1.1 days on a full charge.

Adjust your loadout and runtime

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

Look for ≥800Wh capacity, ~60W continuous / 60W surge or better.

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.
