Best power station for
CPAP & medical
Quiet, reliable overnight power for a CPAP while camping or during an outage.
A CPAP is a light but critical load — typically 30–60W without the humidifier/heater, more with it. The goal is enough usable capacity for several nights, a quiet unit you can sleep next to, and a pure sine wave output that's gentle on the electronics. Turning off the heated humidifier dramatically extends runtime.

Frequently asked
How many nights will a power station run my CPAP? +
Without the heated humidifier a CPAP draws ~30–40W (~300 Wh/night). A 500 Wh station covers about one night; 1,000 Wh gets you two-plus. The heater can double or triple the draw, so turn it off to stretch runtime.
Do I need a pure sine wave unit? +
Yes — reputable power stations output pure sine wave, which is what sensitive medical electronics expect. All units we list qualify.
