US Oxygen Sales carries a variety of portable oxygen concentrators that are designed to accommodate all lifestyles. The lightest portable oxygen concentrator might be right for the individual who travels frequently and has no need for high oxygen concentrator or pulse rates.

For individuals with more severe health demands, perhaps the best portable oxygen concentrator is not the smallest but the one with the highest pulse rate and long-lasting batteries.
