Small Portable Oxygen Concentrators with Long-Lasting Batteries

A portable oxygen concentrator only works well for you, if the battery can last for as long as you need it to without needing to be recharged. Having the smallest portable oxygen concentrator you can get is usually also a high priority! As long as the portable model you want covers your oxygen needs, you shouldn't have to get a large one to have a lasting battery.

There are several portable oxygen concentrators in the small category (5 pounds and under) with batteries that have the ability to last for as long as 8 hours or more. Battery life of an oxygen concentrator battery depends on the setting, the higher settings it won't last as long, because it has to draw more electricity.

However, these small concentrator batteries will still last a lot longer than some of the others that are in the bigger size category. If you want a small oxygen concentrator with a long-lasting battery, you should check out these models.

Lifechoice ActivOx and ActivOx Pro 4L

The Lifechoice ActivOx and the ActivOx Pro 4L are two different portable oxygen concentrator models, but the ActivOx can only go up to 3 LPM equivalence, and the Pro 4L can go up to 4 LPM equivalence. The Pro 4L weighs just 4.8 pounds while the other only weighs 4.3 lbs.

The ActivOx Pro 4L only weighs 5 ounces more, yet offers 1 LPM equivalence more than the regular ActivOx. Another amazing thing about these two, is that with the internal battery can last for as long as 12.5 hours on the ActivOx, and up to 10.25 hours on the Pro 4L. You can add even more battery time to these by adding the external battery.

Inogen One G3 16 Cell Battery

The Inogen One G3 has two battery options, the 8 cell, and the 16 cell. It also only weighs 4.9 lbs with the 8 cell battery installed, but the 16 cell battery will only add 1 more lb, and double the battery life. If you need to use up to 750 ml/min of pulse dose oxygen and need a nice long lasting battery, the Inogen One G3 has you covered.

AirSep Freestyle with AirBelt Battery Pack

Don't need that high of a pulse dose? If you only need up to 498 ml/min, the Freestyle by AirSep offers this at just 4.4 lbs. The internal battery can only last as long as 3.5 hours on the lowest setting, but if you add the AirBelt supplemental battery pack, you can have up to 8 hours of total battery life.

AirSep has a couple different supplemental battery options, both of which add more battery life while only weighing about 1 lb extra. You can wear the AirBelt around your waste, and you just plug it into the concentrator.

    Hi. I am looking for a 2 L portable oxygen with a battery that last for 8 hrs. First time doctor recommended for my aunt to use O2 during the day when she is not home. I guess it will come in a bag to carry it wherever she goes?

    Please let me know the options and prices please. And one more question, can she brings it on a airplane? She will have a trip soon.


    • Ed Rodgers

      Hi! Many oxygen concentrators are FAA approved so they can be brought on a plane. As for the battery, some portables have extended batteries but when travelling it is not uncommon to have multiple batteries where they can be switched out. Lastly, depending on your aunts O2 needs will ultimately determine what type of concentrator will work best. Best thing to do is give us a call at 888-743-0156 and we can help you with identifying the best options for her.
