AirSep Internal Battery

This is the Internal Battery for the AirSep Freestyle 3 and AirSep Freestyle 5 Oxygen Concentrators. The battery is lightweight, durable, and transportable.

AirSep Freestyle 3

The AirSep Freestyle 3 Portable Oxygen Concentrator is a lightweight device weighing less than five pounds. The Freestyle is perfect for the on-the-go oxygen concentrator. It's an FAA approved device with multiple charging options and three different operational modes.

AirSep Freestyle 5

The Internal Battery also works with the AirSep Freestyle 5 Portable Oxygen Concentrator. That device has five different operational modes, and like the Freestyle 3, offers several charging options in one convenient and travel friendly package.

Key Features

  • Lightweight and Portable
  • Compatible with AirSep's Freestyle 3 and 5 Oxygen Concentrators
  • Will Power Your Concentrator

Reviewers Tip:

When you travel with an oxygen concentrator, be sure to carry it on the plane with you. Packing your equipment leaves it susceptible to unnecessary damage.

This battery is intended for use with the Freestyle 3 and 5 only.

Is this a CPAP product?

It is not. It is intended for use with oxygen concentrators.
