The Best Power Stations for CPAP Machines in the UK (2026)
Running a CPAP machine off-grid - camping, in a power cut or away from home - needs the right power station. This guide covers what to look for in a CPAP power station and which models we rate.
Quick answer
For a CPAP, choose a power station with a pure sine wave output, enough watt-hours for one or more nights, and quiet operation. CPAP machines are low-draw but run for hours, so capacity (Wh) matters more than peak output. A 500-1000Wh unit covers most CPAP needs for a night or more, especially if you can run it without the humidifier and heated hose, which use far more power.
Why CPAP is a special case
A CPAP is a low-wattage device that runs all night, so the key is battery capacity, not high output. The big variable is the humidifier and heated hose: these can multiply the power draw several times over. Running CPAP without heated humidification dramatically extends how many nights a power station lasts, which is the single most important tip for off-grid CPAP use.
What to look for
- Pure sine wave output: clean power that suits sensitive CPAP electronics.
- Enough watt-hours: for one or more full nights of use.
- Quiet operation: low fan noise so it does not disturb sleep.
- DC output if your CPAP supports it: more efficient than mains AC.
- A display showing remaining capacity: so you know it will last the night.
Working out the capacity you need
Estimate your CPAP's nightly use from its wattage and hours, then add headroom. As a rough guide, without the humidifier a CPAP often uses modest power, so a mid-size station lasts a night or more; with heated humidification the same station may last only a fraction of that. Check your machine's manual for its draw, and test before relying on it.
Who it suits
A CPAP power station suits campers, caravanners, festival-goers, frequent travellers and anyone wanting backup for power cuts who relies on CPAP therapy. It provides genuine peace of mind for sleep apnoea sufferers off-grid. Match the capacity to how many nights you need and whether you must run the humidifier.
Common mistakes to avoid
- Forgetting the humidifier and heated hose multiply power use.
- Choosing on output watts rather than capacity (Wh).
- Overlooking pure sine wave for sensitive electronics.
- Not testing the setup before relying on it off-grid.
- Ignoring fan noise that could disturb sleep.

Frequently asked questions
What size power station do I need for a CPAP?
It depends on your machine's wattage and whether you use the humidifier. Without heated humidification a 500-1000Wh station often lasts a night or more; with it, far less. Check your CPAP's draw and add headroom.
Can a power station run a CPAP machine?
Yes - CPAPs are low-draw but run for hours, so a pure sine wave station with enough watt-hours runs one well. Running without the humidifier and heated hose greatly extends how many nights it lasts.
Does a CPAP need a pure sine wave power station?
It is strongly recommended - pure sine wave provides clean power that suits sensitive CPAP electronics, reducing the risk of issues. Most quality power stations have pure sine wave inverters.
