Freestyle Comfort Portable Concentrator 16-Cell Battery

The CAIRE Freestyle Comfort Large 16 Cell Rechargeable Battery provides up 8 hours of battery life at a flow setting of 2 when it is fully charged. The 16 cell battery is an ideal power source when you need extra battery life for extended flights or long road trips.

It averages about 6 hours to charge the lithium-ion battery from 0% to 100%. The FreeStyle Comfort recharges the battery pack when it is installed in the concentrator, and it is connected to an external AC or DC power source.

It is lightweight at only 3.1 pounds and measures 7.3 inches wide x 3.1 inches deep x 2 inches high. It’s easy to carry multiple 16 cell batteries in the accessory bag, or in a backpack, making it easy to replace a depleted battery with a fully charged one while on the go. Before using the 16 cell battery pack for the first time, it should be fully charged using either AC or DC power.

Well satisfied.

The product was the lowest price I could find online, still not cheap. Delivered as promised and operated as advertised. I can do a lot more things since I don't have to recharge as often as before. You should include the large battery instead of the small one.
