Airsep Focus External Battery and Charger

*All battery purchases are final sale. There are no returns on batteries.* The AirSep Focus External Battery and Charger is a perfect option for those who have a small AirSep portable oxygen concentrator and want a more convenient alternative for longer battery life. Now with an additional battery, you will be able to charge two of these great lightweight, clip-on batteries at a time. Each will take no longer than 5 hours to charge and take with you. The external batteries are a more efficient and lighter alternative to the AirSep AirBelt which is worn around the waist. The new AirSep External Batteries have a clip on the back which is perfect for securing to your belt, pocket, or the concentrator itself. Plug it into your AirSep Focus, Freestyle, or Freestyle 5 for an extended battery life and day out. The AirSep external batteries will alert you when their charge is getting low by their battery indicator lights. At that point, you can plan on getting to a source of power and can run your concentrator off of its internal battery. Each battery only takes 5 hours to recharge from 0-100%. One battery will last for 3.5 hours on a setting of 2 with the AirSep Focus. With the battery, the Freestyle can give you up to 10 hours on a setting of 1 and 5 hours on a setting of 3. The Freestyle 5 can give you up to 7 hours on the setting of 1 and 2 hours on the setting of 5.
