The best CPAP batteries in 2025—like the Medistrom Pilot Flex, Zopec Explore Mini, and EXP96PRO—stand out for combining long runtime, travel certification, and compatibility with top CPAP machines. They keep your therapy running smoothly anywhere, from long flights to camping trips, even when power is limited.
For those of us who rely on CPAP therapy, a steady power source is crucial for ensuring uninterrupted treatment during power outages, travel, or outdoor activities.
Travel CPAP batteries are external power sources designed for portability and can power a variety of standard and travel CPAP machines. This means that whether you're camping off-grid or on the go, you can maintain your therapy routine. Many of these batteries are even approved by the FAA for air travel, adding to their versatility.
Integrated CPAP battery backup systems are built in to provide backup during power outages, but travel CPAP batteries are specifically designed to be external and portable. Although most integrated batteries can be used for travel, battery-operated CPAP machines and external batteries offer a wider range of compatibility and are more convenient for active lifestyles. This flexibility allows you to keep up with your therapy wherever life takes you.
Let’s take a deep dive into our curated list of the best CPAP batteries in 2025.

How to Choose the Right CPAP Battery
Choosing the right CPAP battery comes down to matching three key factors: runtime, compatibility, and portability.
If you travel often, a lightweight FAA-approved model like the Medistrom Pilot Flex or Zopec Explore Mini offers convenience and safety in transit.
