Lithium Ion Battery for CPAP

Lithium Ion Battery

This lithium ion battery for CPAP will help you power your CPAP machine without a plug in cord, allowing you to take your CPAP anywhere. You can bring your CPAP on the road or to the campground, and you'll always have backup in the case of a power outage with this lithium ion battery for CPAP. Compatible with most ResMed, Respironics, and DeVilbiss machines, the lithium ion battery will provide up to 20 hours of power.

Hours of CPAP Use

Depending on your pressure setting -- and to a lesser extent, your choice of CPAP machine -- you'll have a varaible amount of battery power available. If you use a low pressure setting, say around 6 cm H20, you should be able to use your battery for 15-20 hours. If your pressure setting exceeds 16, you'll likely have a bit less than eight hours of battery life for each charge. For brand-specific estimated run times, please consult the specs tab above.

DC Cord

When you're using this battery, you'll need to use the appropriate DC adapter. This battery is compatible with all machines but only via a proper connection cord. If you use a ResMed machine, for example, you'll need a cord compatible with ResMed products.

Battery Life

Your battery will last longer if you use a lower pressure setting instead of a higher pressure setting. It will also hold a charge longer if you do not use a humidifier, if you keep your pressure setting under 16 cm H20, or if you do not use a BiPAP.

Key Features

  • Up To 20 Hours Of Battery Life
  • Compatible with Nearly Every Manufacturer
  • Power Your CPAP Remotely
  • Never Suffer Through a Power Outage Again

Reviewers Tip:

The battery may be taken on a plane as part of your carry on luggage, but should NOT be checked.


Can I use this battery with a bi-level device?

You can, although the battery may not hold a charge for very long. Bi-levels feature higher pressure settings and require more power to operate than standard CPAP machines. This extra power will drain the battery quickly.

What brands is this battery compatible with?

ResMed, Respironics, and DeVilbiss.

Note that these run times are approximate and depend on several factors, including CPAP machine type and inverter type (if an inverter is being used). The use of a heater on a humidifier will substantially reduce battery run time, probably by more than 50%.
