This wiki has been updated 9 times since it was first published in January of 2019. These CPAP battery backups can take over in the event of a power failure to ensure your machine continues to function without interruption. Many also allow you to run or charge multiple small appliances at a time, and most are compact and lightweight for portability. As a rule, be sure to confer with your doctor before using any electronic device to treat a medical condition at home.

Editor's Notes

November 20, 2020:

Several new or updated models come on board in this update, including devices designed mainly as a backup that runs your CPAP machine as soon as the power goes out, as well as more comprehensive models that can power or charge several small electronics at a time. The powerful Jackery Explorer 1000 offers a high output of 1,000 watts, and features multiple AC power outlets and USB ports that enable you to power or charge up to eight devices at a time. This versatile choice can be charged via a wall outlet, a car cigarette lighter socket, a generator, or a solar panel. It’s convenient as either a backup when your mains power goes out or as a way of juicing up your cell phone, laptop, and more when you’re camping. We also added a much more budget-friendly model in the form of the FF Flashfish 166Wh, which is also designed for on-the-go convenience, thanks to its light weight, compact size, and fold-down carrying handle. It’s protected from problems like overheating and short circuits, and you can stay apprised of its battery status easily with the large, bright LCD.

The newly added Freedom Kit is compatible with a variety of CPAP devices, including Philips Respironics, DeVilbiss IntelliPap, and PR System One machines. You can rely on it for up to three nights of service before it needs to be recharged. This lightweight choice features a handy digital display and comes with various adapters. The Renogy GP10 also joins the list, and this compact, book-sized model is actually a force to be reckoned with when it comes to the ability to power anything from a phone to a mini-fridge. Note that for use with your CPAP machine, however, an adapter will have to be purchased separately. We also replaced the Flashfish 100W with the more powerful, 200-watt FF Flashfish 166Wh. This portable choice is convenient for road trips or camping trips, thanks to its light weight of less than five pounds, its small footprint, and its fold-down carrying handle. One thing to note is that this device is not capable of passthrough charging. Lastly, we replaced the Medistrom Pilot-12 with the Medistrom Pilot-24 Lite, an updated device that’s compatible with select ResMed CPAP machines and features both a built-in LED flashlight and a USB port for charging your electronics. For the sake of your CPAP machine and any other devices you intend to power or charge, you should go with a backup that has an integrated battery management system that safeguards against problems like short circuits and overcharging. Always check with your doctor before beginning any oxygen therapy regimen at home.

February 19, 2019:

The MaxOak K5 garnered the top spot due to how well-suited it is for household use, while the Aeiusny Generator is likely a better choice for active users who are often camping, hiking, or otherwise engaging with the Great Outdoors. However, users should be aware that not every battery is universally compatible, so they should check with a health professional or the manufacturer of their machine before making a purchase to ensure suitability.
