Caire FreeStyle Comfort Small Battery

Since its release in November of 2019, the Caire FreeStyle Comfort portable oxygen concentrator has taken the industry by storm. Offering some of the best battery life (up to 16 hours) of any oxygen concentrator and an impressive oxygen output for patients with high demands (pulse dose settings 1-5), it’s a wonder why any oxygen patients still use outdated technology like compressed oxygen or liquid oxygen to meet their oxygen demands.

Each FreeStyle Comfort comes with an 8-cell battery lithium-ion battery free of charge, however, it’s not uncommon for oxygen patients to want an extra battery as either a backup or to extend their current battery life. 

The FreeStyle Comfort small battery is the same battery that comes with the concentrator by default. It’s very small and lightweight, so it’s easy to store in a purse, handbag, or backpack and it will extend your battery life by up to 8 hours depending on what flow setting you’re using. This is ample time to get out and enjoy your life without ever having to worry about your oxygen supply. Then, once you’re home, you can have your batteries charging overnight so that you’re ready to go out and do the same thing the next day.
