For people who use a CPAP, a power outage at night is more than an inconvenience. A portable power station is a quiet, indoor-safe way to keep the machine running, and it doubles as a camping companion. The key questions are how many nights you need and whether you will use the humidifier.
How many nights will you get?
| Power station | CPAP only (~40 W) | With humidifier (~100 W) |
|---|---|---|
| ~300 Wh (e.g. RIVER 3 Plus) | about 1 night | about 2–3 hours |
| ~1,000 Wh (e.g. SOLIX C1000 Gen 2, Explorer 1000 v2) | about 2–3 nights | about 1 night |
| ~2,000 Wh (e.g. BLUETTI Elite 200 V2) | about 5 nights | about 2 nights |
Estimates for an 8-hour night with about 85 % usable capacity. Check your own machine's power rating; using a DC adapter instead of the AC outlet stretches runtime further.
EcoFlow RIVER 3 Plus: best for most CPAP users
EcoFlow RIVER 3 Plus
For a CPAP used without the humidifier, a compact unit like the RIVER 3 Plus covers a typical outage night. It is light enough to sit on a nightstand and quiet in normal use. Its UPS function means you can leave the CPAP plugged into it every night: if the grid drops, the station takes over almost instantly.
- Affordable and compact
- Fast UPS switchover
- Quiet
- One night at most with a humidifier off
- Too small for other appliances
Anker SOLIX C1000 Gen 2: best for multi-night outages
Anker SOLIX C1000 Gen 2
If outages in your area can last a couple of days, about 1 kWh gives you several CPAP nights, plus phone charging and a light. The fast wall recharge also lets you top it up quickly whenever power comes back briefly.
- Several nights per charge
- Also runs a fridge or lights
- Very fast recharge
- Heavier and pricier than a small unit
Jackery Explorer 1000 v2: best for camping with a CPAP
Jackery Explorer 1000 v2
Camping with a CPAP is much easier with a 1 kWh unit you can actually carry. The Explorer 1000 v2 is one of the lightest in its class and can be recharged with solar panels during the day.
- Light for its capacity
- Simple to use
- Solar recharging
- Not expandable
How to choose a power station for your CPAP
1. Check your CPAP's power use
Look at the power supply label or your manual. Most machines without humidifier use 30 to 60 W.
2. Decide on the humidifier
The humidifier is the biggest energy user. If you can sleep without it during an outage, a much smaller station is enough.
3. Look for UPS mode
It is what lets the station take over automatically at night without waking you up.
4. Consider a DC adapter
Many CPAP brands sell a 12 V DC cable that avoids inverter losses.
