Freestyle Comfort Portable Concentrator 8-Cell Battery

The CAIRE Freestyle Comfort Small 8 Cell Rechargeable Battery provides up 4 hours of battery life at a flow setting of 2 when it is fully charged. The 8 cell battery is a perfect power source when you need extra battery life for flights or other outdoor activities.

It averages about 3.5 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 1 pound and measures 7.3 inches wide x 3.1 inches deep x 1 inch high. It’s easy to carry multiple 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 8 cell battery pack for the first time, it should be fully charged using either AC or DC power.
