1. Jackery Explorer 300 Plus: Lightest One-Night Pick

At just over 8 pounds, the Explorer 300 Plus is the easiest unit here to carry into a bedroom, tent or hotel room. Its 288Wh LiFePO4 battery is enough for one full night for many CPAP users if the humidifier is switched off and the machine runs from a 12V DC cord plugged into the car-style port. With the humidifier on, plan on a shorter night. It also recharges quickly from the wall, so it is ready again by the next evening.

Key specs

  • Capacity: 288Wh, LiFePO4
  • AC output: 300W continuous (600W surge)
  • DC: 12V/10A car port
  • Weight: about 8.2 lb
  • AC recharge: roughly 1 hour 15 minutes to full, per Jackery
👍 Pros

  • Very light and compact
  • Long-life LFP chemistry
  • Quick wall recharge
👎 Cons

  • Too small for humidified multi-night use
  • 300W inverter limits what else you can plug in

What owners say: Buyers like how little space it takes on a nightstand and how easy it is to pack. The main limitation people mention is capacity: it suits a single night with the humidifier off rather than an extended outage.

2. EcoFlow RIVER 3 Plus: Best Small Unit for Home Backup

The RIVER 3 Plus pairs a 286Wh LFP battery with a 600W inverter and a rated switchover time under 10 milliseconds, which StorageReview measured at about 9 ms in testing. That matters if you want to leave your CPAP plugged into the station overnight as a UPS so a blackout never interrupts therapy. If one night is not enough, you can add an extra battery to reach 572Wh or 858Wh.

Key specs

  • Capacity: 286Wh, LiFePO4 (expandable to 858Wh)
  • AC output: 600W continuous (1,200W surge)
  • DC: 12V/10A car outlet
  • Weight: about 10.4 lb
  • UPS switchover: under 10 ms
  • Rated IP54
👍 Pros

  • Fast UPS switchover for bedside use
  • Expandable capacity
  • About one hour to recharge from AC
👎 Cons

  • Base capacity is modest
  • Extra batteries add cost

What owners say: Reviewers and owners praise the quick switchover and the option to grow capacity later. The common caveat is that the base 286Wh pack is small for humidified use unless you buy the add-on battery.

8. ALLPOWERS R1500: Most Capacity per Dollar

The R1500 gives you 1,152Wh of LFP storage and an 1,800W inverter, often for less than 1kWh units from bigger brands. Beyond the 12V car port, it has extra 12V/24V DC outputs. The catch is weight: at nearly 37 pounds it is the heaviest unit here, so it suits a home backup role more than camping. Note that the R1500 LITE is a different, smaller model.

Key specs

  • Capacity: 1,152Wh, LiFePO4
  • AC output: 1,800W continuous (3,000W surge)
  • DC: 12V/10A car port plus 12V/24V DC outputs
  • Weight: about 36.8 lb
  • UPS switchover: 15 ms
  • AC recharge: 0-80% in about 45 minutes
👍 Pros

  • Most capacity in this guide
  • Strong price for the size
  • Fast charging
👎 Cons

  • Heavy
  • Slightly slower switchover

What owners say: Owners generally see it as a lot of capacity for the money. Weight is the main drawback people raise.

How to choose a power station for CPAP

For a quick estimate of capacity, try our power station and generator sizing calculator. Then weigh these factors:

  • Know your machine’s draw. According to ResMed’s battery guide, an AirSense 10 draws roughly 8-20W on 12V DC with the humidifier off, but up to about 50-55W with the humidifier running. A heated tube adds more. Check your own machine’s manual or ask your equipment supplier for exact figures.
  • Do the runtime math, then pad it. A common rule of thumb is: hours = battery Wh x 0.85 / CPAP watts. A 288Wh unit at 12W on DC works out to about 20 hours, while the same unit at 40W gives about 6 hours. Real results are often lower, especially on AC: Outdoor Life found that large power stations delivered only about half their rated capacity at very small AC loads because the inverter uses power too.
  • Use DC when you can. ResMed notes that DC converters are more efficient than inverters, and cpap.com warns that an inverter adds its own draw. Use the manufacturer’s DC cord for your model; cpap.com cautions that third-party converters can damage some machines.
  • Turn off the humidifier and heated tube on battery. cpap.com says these have the biggest impact on runtime. If you need humidity for comfort, size up to a 1kWh-class unit.
  • Look for a fast UPS switchover. If the station will sit plugged in at your bedside, a switchover of 10-20 ms or less helps keep the machine running when the power drops. Confirm your machine tolerates it before relying on it.
  • Choose LiFePO4. All picks here use LFP chemistry, which cpap.com notes lasts thousands of cycles versus a few hundred for older lithium-ion packs.
  • Think about weight and travel. Small 8-12 lb units are easy to bring camping. cpap.com notes that batteries over 160Wh are not approved for carry-on air travel, so none of these stations can fly with you.

FAQ

How long will a 1,000Wh power station run a CPAP?

It depends on your settings. With the humidifier off and a DC cord drawing around 10-20W, a 1kWh unit can last several nights. With the humidifier on and running through the AC outlet, expect closer to one or two nights. Always test at home before you depend on it.

Is it better to plug a CPAP into the AC outlet or the DC port?

DC is usually more efficient because it skips the inverter. Buy the DC power cord or converter made for your specific CPAP model and plug it into the station’s 12V car port.

Can I use a power station as a UPS for my CPAP?

Many of these units offer a UPS or EPS mode that switches to battery when the power fails. Switchover times range from about 8 to 20 ms. Follow both the CPAP and power station manufacturers’ guidance, and talk to your equipment provider or doctor if uninterrupted therapy is medically critical for you.

Can I bring a portable power station on a plane for my CPAP?

Not these models. cpap.com notes that batteries above 160Wh are not approved for flights. Airline-approved CPAP batteries are a separate category.
