The intended use of a portable oxygen concentrator is slightly different than that of a home oxygen concentrator. A portable oxygen concentrator is typically intended for short-term usage outside of the home in lieu of a portable oxygen tank. Portable oxygen concentrators are designed to be much smaller and lighter than a stationary oxygen concentrator. Most portable oxygen concentrators weigh around 10 pounds with one battery, but there are both lighter and more substantial models available. Portable oxygen concentrators are also different from home oxygen concentrators because they can run solely off of battery power, or can provide oxygen when plugged into a wall outlet or a DC converter for use and charging while driving in a car. We carry eight models of new and used portable concentrators, all with different specifications. Six of the models we carry are FAA-approved for use in airline travel.
