How long will a power station run a CPAP?

Catalog CPAP is 60W without a heated humidifier, 100W with one. A night on this page is 8 hours. Nights = usable Wh / (watts x 8).

Hours use usable watt-hours: nameplate Wh x 0.80 depth of discharge x 0.90 inverter efficiency. The 1.25 sizing buffer is for buying a new battery. It is not used for hours of a station you already own.

Catalog notes: 30-60W without heated humidifier. Heated humidifier can draw 100W+. This page uses 60W and 100W.

Only power stations Field Authority has signed appear here. Catalog SKUs without a lock-file row stay off this table.
