AirSep External Battery
These batteries will also let you know immediately when the charge is getting low, so you have time to go to a power source to run or charge the battery or the concentrator's internal battery. An indicator light will change to let you know how much battery life is left.
The AirSep External Batteries are the newest product for the brand that created some of the best small oxygen concentrators, the Focus, Freestyle and Freestyle 5. These external batteries are lightweight and more convenient to use than the AirSep AirBelt, and they can both be charged at the same time, separately from the concentrator. These batteries are a great alternative for those who want more battery life for their AirSep portable oxygen concentrator.
They are small and light enough to wear underneath a jacket, to make your oxygen therapy use even more inconspicuous. You won't need to fuss with a belt – just clip the battery to your belt or pocket, and plug it into the concentrator when you are ready to add more hours to your battery life.
Each battery only takes 5 hours to charge up, from 0% to 100%, and can be charged individually via the AC or DC power cords. One battery will last for 3.5 hours on the setting of 2 in the AirSep Focus. With the Freestyle, you will get up to 10 hours of battery life on the setting of 1, and 5 hours on the setting of 3. On the Freestyle 5, you can have up to 7 hours on the setting of 1, and 2 hours on the setting of 5.
