As a rule of thumb, when purchasing a POC you want to get the lightest one possible. In some cases that may turn out to be an 18 pound unit and in other cases it may be a 4 pound concentrator. In the event that you are able to use an extremely lightweight portable oxygen concentrator you are left with a tough decision. There are quite a few lightweight POCs to choose from and here is a portable oxygen concentrator comparison of the Inogen One G3 and the LifeChoice Activox.
Oxygen Output/Flow Rate
Inogen One G3: The G3 offers pulse flow settings 1-4 adjusting in increments of 1. On all settings the oxygen concentration is 90% +/- 3%.
LifeChoice Activox: The Activox offers pulse flow settings of 1-3 adjusting in increments of 1. On all settings the oxygen concentration is 90% +/- 3%.
The Inogen One G3 offers one more pulse flow setting than the Activox. Although it is not that big of a difference, it’s nice to have the insurance knowing you can go up to 4.
Inogen One G3: The Inogen One G3′s weight varies depending on which battery you use. With the 8 cell battery the G3 weighs a mere 4.8 pounds. With the 16 cell battery it weighs 5.8 pounds. Here are the dimensions of the G3: 7.25″ x 3.0″ W x 8.75″D.
LifeChoice Activox: The LifeChoice Activox only weighs 4.83 pounds. With the optional external battery, the Activox weighs 5.83 pounds. Here are the Activox dimensions: 7.8″ H x 9.05″ W x 4.38″ D.
Both of these units are extremely portable and lightweight. There is no clear winner in this category, both units are some of the smallest in the world.
Inogen One G3: The Inogen One G3 is a pretty quiet unit. Running at 42 decibels on a setting of 2, the G3 is quieter than a normal conversation from 3 feet away.
LifeChoice Activox: The LifeChoice Activox is going to be a little louder than the G3. On a setting of 1 the Activox runs at 41 decibels. The sound level increases when you increase the oxygen output.
Inogen has excelled at keeping noise level to a minimum with their concentrators. Even the older Inogen One G2 runs quietly and efficiently.
Inogen One G3: Inogen concentrators are also known for their battery life. The G3 has two different battery types, an 8 Cell Battery (single battery) and a 16 Cell Battery (double battery). Here is a chart showing the expected battery life for the Inogen One G3:
|Flow Rate||Battery Life 8 Cell / 16 Cell|
|1||6 Hrs / 12 Hrs|
|2||4 Hrs / 8 Hrs|
|3||3 Hrs / 6 Hrs|
|4||2 Hrs / 4 Hrs|
LifeChoice Activox: The LifeChoice Activox has one internal battery with an optional external battery. The external battery does not come standard with the Activox. Here is a chart showing the expected battery life of the Activox:
|Pulse Flow Setting||Internal Battery||External Battery||Total Battery Life|
|1||8 Hours||3 Hours||11 Hours|
|2||6 Hours||3 Hours||9 Hours|
|3||5 Hours||2 Hours||7 Hours|
Both portable oxygen concentrators get great battery life. They also give you an additional way to get more battery life. For the G3 you can get the double battery (16 cell) to boost your battery life. With the Activox all you need is the optional external battery to get additional battery life.
Altitude Operating Range:
Inogen One G3: The G3′s operating altitude range is 0-10,000 feet (3048 m). Should you go higher than the specified operating altitude range, the performance of your concentrator will suffer.
LifeChoice Activox: The Activox’s operating altitude range is 0-10,00 feet (3048 m). Should you go higher than the specified operating altitude range, the performance of your concentrator will suffer.
The altitude operating range for POCs is pretty standard across the board. If you are planning on flying somewhere with your concentrator don’t worry, the airplanes are pressurized to about 8000 feet.
Inogen One G3: The Inogen One G3 uses a 5 button control panel with a back-lit LCD screen. There are also two LED visual alarm lights. On the right side of the control panel there is the power button, audible alarm button, and display back-light button. The flow control buttons are located underneath the LCD screen.
LifeChoice Activox: The Activox uses a 6 button display with LED indication lights. This control panel is very easy to use and navigate. On the top of the control panel are the flow rate buttons. Below the flow rate buttons are the mute button and battery check button. The battery check button can be used to check the remaining battery life on both the internal and external batteries. The power button is on the left side of the control panel.
