Who It's For

People who need long continuous oxygen support for many hours at a time should consider stationary concentrators or systems with longer battery runtime, because this models battery lasts about 1 to 1.5 hours when fully charged. Also, those highly sensitive to device heat should note some reports of the unit becoming warm during extended operation.
