Batteries and Power Supply

Batteries, power supplies and cables for CPAP therapy. A battery is worth considering for camping, caravanning, remote accommodation, long-haul travel and power outages — anywhere you cannot count on a standard power outlet.
Runtime depends on your pressure setting and whether you use humidification, so it is worth working out how long your own setup will last before you travel. Our guide to CPAP battery options explains what to look for, and travelling with CPAP covers the rest of the trip.
