  • Battery Life

If you have a AirSep Focus or Freestyle 3 or Freestyle 5 portable oxygen concentrator, one of the ways you can add extra battery duration is with the AirSep AirBelt. Worn around the waist, you can plug it in to the concentrator when you need it. If you’re not sure if this battery pack is right for you, read on.

The Good

This external supplemental battery weighs just 1 lb, but can hold a charge to back up your Focus or Freestyle battery life for another 3.5 hours potentially. On the setting 1 on either portable concentrator, you can get as much as 3.5 more hours of complete mobility. On the setting of 2, you can enjoy up as long as 2.5 hours, and on the setting of 3 you will get 2 extra hours. Another great thing about the AirSep Airbelt is the fact that it can be worn around your waist. This makes it easy to wear it discreetly and comfortably, as it won’t weigh you down or stick out and become a nuisance.

The Bad

There is really nothing bad to say about the AirBelt, except that it might not fit everyone’s waist if you are over a certain weight. It’s almost one size fits all and adjustable to a point. If it doesn’t fit you, you can try the AirSep External Battery instead.

The Bottom Line

A great addition to your AirSep Focus or Freestyle accessories, if you need more battery duration than what you get with the internal batteries of the two models. It plus right into the Focus or Freestly in the external battery port, and is the economical option for adding extr battery life to your concentrator. It’s a good idea to get at least one AirBelt if you plan on doing a lot of traveling. You will be able to charge the AirBelt separately from the concentrators, making it easy to charge up your supplemental batteries for later use when you need the added time.
