You won’t mind going out and about with the incredibly small and lightweight Inogen One G3. It has the potential of delivering the oxygen you need if you need a high flow of pulse dose oxygen. If you’re not sure if this model is right for you, here are the facts.

The Good

The groundbreaking Inogen One G3 gives you the option between two different battery sizes, both of which offer an amazing battery duration. You can get an average of 4 hours of battery life on the smallest of the two batteries (the 8 cell) and as much as 8 hours on the 16 cell battery, depending on your setting. Even on a high setting, you will still enjoy more battery life than many other top brand portable oxygen concentrators. The Inogen One G3 is also a step up from the previous G2, in the way that it is even smaller. This portable oxygen concentrator only weighs 4.9 lbs with the 8 cell battery inside.

The Bad

The batteries take a while to charge up from 0% to 100%. Around 2 to 4 hours for the 8 cell, and around 5 to 8 hours for the 16 cell to completely recharge. This is why it’s always a good idea to have at least one more extra battery – so you don’t need to wait around if you need to continue using your oxygen therapy.

The Bottom Line

As long as the Inogen One G3 can cover your oxygen needs prescribed by your Dr., this is a great portable for anyone who likes to get around, and doesn’t have a lot of time to sit down and recharge their concentrator battery. The fact that there are 2 battery sizes is for economical reasons, making it easy to add twice as much battery life exactly when you need it. For example, if you already have the standard 8 cell and you are about to go on vacation, you can spring for the 16 cell to make sure you have plenty of time between recharges. All around, this pulse dose only concentrator is great for those who are very busy, who can’t be held down.
