An easy to read battery gauge light on the control panel indicates 25%-100% battery life notifications. The battery cartridge is easy to replace with another fully charged cartridge while on the go. The battery provides up to 2-1/2 hours of operation on setting 2 and recharges. With a 5-liter equivalent oxygen output in a pulse flow, the FreeStyle 5 provides oxygen therapy wherever you want to go. A 3-year warranty covers all the components, including the sieve bed.

Very unhappy
Very disappointed in this product. It will only stay charged at a level 2 setting for about two hours. Also I ordered the belt battery pack and the belt will not fit around my waist by several inches so there is no good way to carry it
AirSep Portability
These AirSep Concentrators are all about portability. I got there largest size portable oxygen concentrator and find that it still is very low weight so it is not so heavy on me. At less than 6 pounds with a battery, I can go to lots of places I use to avoid.
