The AirSep brand is truly a marvel in the oxygen concentrator market. They've made some of the best portable and stationary oxygen concentrators around, as well as some of the smallest and most convenient accessories to go along with them. AirSep has done it again with the brand new AirSep External Battery, a great alternative for adding more battery life to your AirSep Portable Concentrators.
The AirSep External Battery is only 1 lb, and is smaller and easier to transport. You can even hide it under your shirt, clipped to the waist of your pants or the edge of your pants pocket. Previously, those who wanted supplemental battery life for their AirSep portable concentrator, had the option of getting the AirSep AirBelt. The AirBelt weighs 2 lbs, and is worn around the waist, with the ability to be plugged into the concentrator.
