Now you can easily charge external batteries for your AirSep Focus, Freestyle and Freestyle 5 portable concentrator, with the AirSep External Battery Charger and one external battery. This efficient external battery charger will take no longer than 5 hours to charge up both batteries.
These external batteries are a lighter and more convenient alternative to the AirSep AirBelt, for more battery life. The AirSep external batteries feature a clip on the back, which makes it easy for you to clip to your belt or pocket when you are ready to add more battery to your Focus, Freestyle and Freestyle 5.
You won't need to fuss with putting on a belt, as was the case with the AirSep AirBelt. You won't need to guess how long the battery will last, because the indication lights will let you know when the battery is getting low.
You can also charge both external batteries on the charger at once. This will save you a lot of time. 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.
