10 Best Battery Backup For Cpap Machine 2025 in the United States

The Renogy 76800mAh (276.48Wh) Power Bank Brick is a strong option if you need portable battery backup for your CPAP machine, especially when camping or during power outages. It supports most popular CPAP models like ResMed AirMini, AirSense, AirCurve, and Philips DreamStation, though it doesn't work with the ResMed S9. With a large battery capacity, it can run a CPAP through the night if you turn off the heater and humidifier, so it's best for basic CPAP use rather than full humidification.

Charging is flexible and quick, with four ways to recharge including a fast 100W USB-C input that takes about 3-4 hours, plus options for car or solar panel charging. Portability is good—at just under 3 pounds and compact size, it's lighter and smaller than many CPAP batteries, making it handy for outdoor use. It also powers up to six devices at once, including wireless charging and a car socket, which adds versatility beyond CPAP use. Safety features like advanced battery management and an SOS flashlight provide extra peace of mind.

This power bank is not approved for air travel, which may limit some users. Also, the CPAP compatibility excludes humidifier use for longer battery life, which could be a drawback if you rely heavily on humidification during sleep. The device serves as a reliable, multi-use portable power source suited for CPAP users who prioritize portability and flexible charging options while camping or during emergencies.

The Renogy 72000mAh 266Wh Power Bank is a solid choice for those needing a reliable battery backup for their CPAP machines, especially during camping trips. With a massive battery capacity of 72000mAh, it offers substantial power to keep your CPAP machine running for extended periods, even off the grid. The compatibility with popular CPAP models like Philips DreamStation and ResMed AirSense (adapter sold separately) makes it a versatile option for many users.

Additionally, it features a high conversion rate of up to 90%, ensuring efficient use of power. However, keep in mind to turn off the heater and humidifier for the best performance. The power bank's portability is commendable, weighing only 2.79 pounds and having compact dimensions (8.98 x 4.92 x 1.73 inches), making it easy to carry. The inclusion of a flashlight and wireless charging pad adds convenience, although the wireless charging is not suitable for low-power devices like wireless earbuds and smartwatches. Recharging the power bank is relatively quick, with options to use either a solar panel or the USB-C port, taking between 3 to 6 hours.

One drawback is that it’s not TSA-approved for air travel, which could be a limitation for frequent flyers. Also, the CPAP adapter needs to be purchased separately. Despite these minor inconveniences, the Renogy power bank is an excellent backup power supply, especially for outdoor enthusiasts who rely on CPAP machines.
