Best power station for CPAP
How many nights each station runs a CPAP machine, with and without the heated humidifier. Based on 8-hour nights.
Jackery Explorer 2000 v2
About 5.4 nights without the humidifier, or 2.4 with it. Heavy, but it covers a long weekend or a multi-day outage.
Anker SOLIX C1000 Gen 2
About 2.7 nights at 40 W, with 2,000 W left over for a fridge or kettle-sized loads during the day.
Nights per charge
AC outlet at 85% efficiency. The DC-only Anker uses 92% through a 12 V CPAP adapter.

What uses the power
Most CPAP machines draw 30 to 60 W on their own. The heated humidifier and heated tube can double or triple that, which is why the humidifier column drops so sharply. Turning the humidifier off, or lowering its setting, is the biggest single way to stretch a charge.
Use a DC adapter if you can
Many CPAP makers sell a 12 V DC cable or converter. Running from the station's 12 V port skips the inverter and gives you roughly 8% more runtime than the AC outlet.
Why 300 Wh stations aren't enough
A 288 Wh station like the Jackery Explorer 300 v2 lasts about six hours at 40 W, short of a full night. They work as a top-up, not as your only source.
This page compares power stations, not medical devices. Ask your equipment supplier or doctor before running a CPAP from battery power, and check your machine's real draw in its manual.
