What to look for

Work out your runtime

Divide the station's Wh by your CPAP's watt draw, then multiply by about 0.85. A 40 W draw on a 640 Wh station is roughly 13 hours.

DC and humidifier

A 12 V DC cord (sold by most CPAP makers) avoids inverter losses, and turning off the heated humidifier can cut consumption a lot.
