Are you looking for the best portable power station for CPAP machines to ensure a safe night’s sleep during camping or blackouts?
For millions of people, a power outage isn’t just an inconvenience—it’s a health risk. If you rely on a CPAP machine for sleep apnea, the thought of a storm knocking out the grid (or going camping off-grid) can be terrifying.
You don’t just need a battery; you need reliability, silence, and enough capacity to get through the night.
We have analyzed the market to find the best portable power station for CPAP users in 2025, focusing on real-world runtime and safety.
🚨 Critical Tip: The “Humidifier” Factor
Before you buy, you must understand one technical fact: Heat kills batteries.
- CPAP with Humidifier/Heated Tube ON: Consumes ~60W to 90W (Drains battery in 4-5 hours).
- CPAP with Humidifier OFF: Consumes ~30W to 40W (Lasts multiple nights).
Pro Advice: To double your runtime instantly, turn off your humidifier heater and use a DC Converter Cable specific to your machine (like ResMed 12V cable) instead of the standard wall plug.
🏆 Quick Recommendations (At a Glance)
| Scenario | Best Choice | Why? |
| Hiking / Light Camping | Jackery 300 Plus | Fits in a bag, silent, runs CPAP for ~1 night (Eco mode). |
| Home Backup (Blackout) | EcoFlow DELTA 2 | Fast recharging, runs CPAP for 3+ nights. |
| RV / Long Trips | Jackery 1000 v2 | Rugged, high capacity, solar efficient. |
Scenario 1: The “Weekend Camper” (Lightweight)
You want to sleep under the stars, but you can’t lug a heavy generator. You need something that fits on a small tent table.
Winner: Jackery Explorer 300 Plus
This unit is a marvel for its size. It uses LiFePO4 batteries (safe for 10 years) and operates almost silently in “Quiet Mode” (under 30dB), which is crucial when sleeping next to it.
- CPAP Runtime (Humidifier OFF): ~6-7 Hours.
- Verdict: Perfect for one night of sleep. You must recharge it the next day using solar panels or your car.
Scenario 2: The “Home Security” (Reliable Backup)
The storm is raging, and the power goes out. You need absolute certainty that your machine will run tonight, and maybe tomorrow night too.
Winner: EcoFlow DELTA 2
With 1024Wh of capacity, this is a beast. It allows you to run your CPAP with the humidifier on for a full night, or without it for 3-4 nights. Its superpower is X-Stream charging (0-80% in 50 mins), so if the power comes back for just an hour, you can refill it completely.
- CPAP Runtime (Humidifier OFF): ~20-25 Hours.
- Verdict: The best insurance policy for home users.
Scenario 3: The “Off-Grid Nomad” (Durability)
You are in an RV or Overlanding for a week. You need something that handles bumps, dust, and keeps your medical equipment running alongside your phone and fridge.
Winner: Jackery Explorer 1000 v2
The updated V2 model is smaller and lighter than its predecessor but packs 1070Wh. It matches the EcoFlow in capacity but comes in a form factor that is easier to pack in vehicles.
- CPAP Runtime (Humidifier OFF): ~21-26 Hours.
- Verdict: The rugged choice for extended trips.
🧮 How to Calculate Your Exact Runtime
Don’t guess; use math. Find the “Wattage” on your CPAP’s power brick (e.g., 60W).
💡 The Formula:
(Power Station Capacity Wh × 0.85) ÷ Device Watts = Hours
📝 Real World Example:
Using Jackery 300 Plus (288Wh) with a 40W CPAP:
288 × 0.85 ÷ 40 = 6.12 Hours
Conclusion: Choosing the Best Portable Power Station for CPAP
Sleep apnea shouldn’t stop you from exploring or sleeping soundly during a blackout.
- Go for the Jackery 300 Plus for portability.
- Choose the EcoFlow DELTA 2 for maximum home security.
