LifeChoice ActivOx Pro 4L Portable Oxygen Concentrator


This portable concentrator weighs just 4.8 lbs, and measure to 9.05" wide by 7.875" high by 4.38" deep. The internal battery alone can last up to 10.25 hours. The battery duration depends on which oxygen dosage setting you are using. 10.25 hours for setting 1, 8.25 hours on setting 2, 5 hours on setting 3, and 4 hours on setting 4. The internal battery takes a total of 4 hours to charge from 0 to 100%.

The ActivOx 4L offers pulse dose oxygen settings with equivalent of 4 LPM (liters per minute) at an average purity of 90%. This portable concentrator also features the exclusive PULSE WAVE delivery system, as well as “Auto Mode”, which sync to your natural breathing patterns, and change as soon as your breathing patterns change. These features add extra comfort to your oxygen therapy experience.

The loudest noise level was recorded at 44 decibels on the highest setting, which in comparison, is no louder than a bird's chirping. The control panel is located on the top of the concentrator and is easy to read and operate. There is a power button, +, -, and “OK” setting buttons to set your dosage, the cannula tube nozzle on the top of the concentrator, and the display screen in the center, which can show battery meter bars, alarm messages, level setting, auto mode and PULSE WAVE settings and shows whether or not the alarm system is muted.

The alarm system includes low battery, low oxygen purity, high temperature, no breaths detected, and when a reset is required. When attention is needed due to these things, an audible tone will go off, unless the audible alarms are muted, the red alarm indicator light will turn on the control panel, and the title of the alarm will show on the display screen, so you know which problem to address. Refer to the owners manual on the causes and how to fix each issue if they occur.

Comes with a standard 3 year limited manufacturer's warranty. With the ActivOx 4L package, you will also get the compatible AC power supply, the DC power supply, a standard 7-foot long single lumen nasal cannula, and the owners manual.

You'll also get the carry case which can be carried 4 different ways with the adjustable straps (backpack style, shoulder bag, waist pack or briefcase style), as well as a matching accessory bag. The carry case features an opening on the side, so you can easily plug in the external battery when you need it. The ActivOx external battery is sold separately, but is compatible with the ActivOx 4L.

  1. Great Deal on my New ActivOx 4L.

    Posted by Bob E. on Apr 25th 2016

    I really think I got a great deal on my new ActivOx 4L. I now require 3 liters of oxygen so this device gives me some flexibility.

    It not only works well for me today, but i believe that it should work for me in the future if I ever need more than 3 liters per minute. (hope not)
    I am truly amazed at how lightweight this oxygen machine is and it makes going everywhere seem easier.

  2. I love this Activox Portable Concentrator

    Posted by Sam D. on Apr 25th 2016

    I love this Activox Portable Concentrator, I purchased and wear as a backpack and it gives me so much freedom. I can do more now than I have been able to do in along time.
    This is also a fantastic company to purchase from. I am very happy with this portable concentrator and hope to do business with this company again.
