As an oxygen therapy patient, you'll naturally be concerned about the performance of your portable oxygen concentrator (POC).

The most important area is that of your concentrator's battery life. After all, the more battery life your device can offer, the better and longer freedom you can expect.

When you are considering portable oxygen concentrators, the battery life will be first and foremost to put your attention on, especially if you have an active lifestyle that includes things like longer distance traveling, spending a day on the lake, golfing, and fishing that require a longer battery life. 

POCs With Great Battery Life

When you're considering portable oxygen concentrators, there are three models that provide extended battery lives. These top three are:

• LifeChoice Activox Pro
• Inogen One G3
• Inogen One G2

Let's look at these three POCs and introduce you to what they can offer your busy life.

LifeChoice Activox Pro

The FAA-approved LifeChoice Activox Pro is among the lightest portable oxygen concentrators, weighing in at a mere 4.3 pounds. It's also small in size, coming in at 7.875" in height. With its 4-way carrying case, you have several options in wearing it so you're hands-free when you need to be.

The LifeChoice Activox Pro has an internal battery that can provide you with up to 7.25 hours of continuous usage on a pulse flow setting of 2. If you combine it with the optional external battery, you can gain up to 10.25 hours on a pulse flow setting of 2.

The LifeChoice Activox Pro also comes with Auto Mode Technology and PULSE-WAVE Technologies that deliver and adjust your oxygen by monitoring any changes in your breath rate and enable you to receive your full required dose.

Inogen One G3

The FAA-approved Inogen One G3 is ideal for when you want true mobility without the need for a cart to transport it.

This POC is a compact 7.25" high and just 3" wide. It weighs only 4.8 pounds and with its over the shoulder carrying bag, you're free to do anything you'd like.

There are two batteries available for the G3. The 8-cell battery offers up to six hours with a 2-4 hour recharge time. Its 16-cell battery can provide up to 12 hours of battery life on a setting of 1. It also comes with both an A/C and D/C power supply.

The G3 offers you pulse settings ranging from 1 – 4. 

It is also one of the quietest concentrators available, rated at approximately 42 decibels while the level of conversation is about 65. 

It will not drown out conversations or the sound of the television. Its also ideal for nighttime use. 

It is equipped with sleep technology to detect shallower breathing and maintain constant oxygen saturation.

Inogen One G2

The FAA-approved Inogen One G2 is another of the robust portable oxygen concentrators.

It is slightly larger and heavier than the Inogen One G3 and the LifeChoice Activox Pro coming in at seven pounds and standing about 9.5 inches in height.

It comes with an easy-to-maneuver travel cart that has a telescoping handle, so you can get around easily wherever you're going.

The G2 can go up to a 5 setting on pulse flow. It provides you with up to 10 hours of battery life on a 1 setting with the 24-cell battery or five with the 12-cell battery.

The G2 also supplies you with Intelligent Delivery Technology. This automatically senses shallower breathing at night. As your breathing rate decreases, the bolus dose increases. It's also one of the quietest concentrators available, rated at just 38 decibels.
