Camping with a CPAP Machine: Power Solutions for Sleep Apnea Outdoors
Sleep apnea doesn't take a vacation — and neither should you. One of the most common questions we get from campers with CPAP machines is simple: how do I keep it powered? The good news is that with the right portable power setup, running a CPAP at the campsite is very doable. Here's what you need to know.
How Much Power Does a CPAP Actually Use?
Most standard CPAP machines draw between 30–60 watts per hour without a heated humidifier, and 60–100W with one. Over an 8-hour night, that's roughly 240–800Wh depending on your machine and settings. The takeaway: you don't need a massive power station, but you do need to choose the right one for your setup.
Pro tip: Turn off your heated humidifier when camping — it's the single biggest power draw on a CPAP. Most machines run fine without it, and a 12V DC adapter (if your machine supports one) is significantly more efficient than running off an AC inverter.
Power Station Options
For 1–2 Nights: Mid-Capacity Power Stations
For a weekend trip without solar recharging, you need a power station with at least 300–500Wh of usable capacity. This comfortably covers 1–2 nights of CPAP use without a humidifier, with room left for phone charging and a lamp.
Look for a unit with a true sine wave inverter — CPAP machines are sensitive electronics and some don't play well with modified sine wave power. Most quality portable power stations use true sine wave output.
For Extended Trips: High-Capacity + Solar
For longer stays or dispersed camping where you can't plug in, pair a higher-capacity power station with a solar panel for daily recharging. The Nature's Generator Elite Power Pod (1200Wh) and Standard Power Pod (1200Wh) are solid expansion batteries for multi-night setups. For maximum capacity, the Nature's Generator Lithium 3600 Power Pod (3072Wh) and Lithium 6000 Power Pod (3840Wh) give you serious capacity for extended off-grid use.
Pairing with Solar for Off-Grid Recharging
If you're camping somewhere with decent sun exposure, a solar panel can keep your power station topped off daily — eliminating range anxiety entirely. A single 100W rigid solar panel will recover roughly 300–500Wh on a good sun day, which covers most CPAP users comfortably. For faster charging or cloudy conditions, step up to the 400W folding solar panel or the 440W 2-pack (880W total) for maximum recharge speed.
Need to run cable from your panels to a shaded setup area? The 50ft solar panel extension cable gives you plenty of flexibility to position panels in full sun while keeping your power station in the shade or inside your tent.
Practical Tips for CPAP Camping
- Use a 12V DC adapter if your CPAP supports it — it's 20–30% more efficient than AC and will stretch your battery significantly further.
- Disable the heated humidifier — or use a pass-over humidifier that doesn't require power.
- Check your CPAP's altitude settings — some machines need manual adjustment above 8,000 ft.
- Bring a backup battery — even a small 12V lithium battery pack gives you an emergency buffer.
- Test at home first — run your setup for a full night at home before your trip so there are no surprises at the campsite.
The Bottom Line
A CPAP machine doesn't have to be a barrier to camping. With a properly sized power station and a solar panel for longer trips, you can sleep just as well outdoors as you do at home — maybe better. The key is matching your power source to your machine's actual draw and your trip length.
