You’ll love leaving the house with the small and lightweight Inogen One G2. 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 lightest portable oxygen concentrator that provides a maximum pulse dose setting of 6. The Inogen One G2 is only 7.25 lbs and is no bigger than the average purse. The G2 is also one of the quietest portable models, humming no louder than 38 decibels. You have the option to go with a standard 12 cell battery (which automatically comes with the Inogen One G2), or if you need more battery life, you can opt for the 24 cell battery to come with it, or you can purchase it later if you feel the need. This is great for those who want to save money up front, because they aren’t sure if they will need the other one later, in the case of a long trip.

The Bad

The only bad thing about the G2 is the amount of time it takes to charge the batteries. It takes 4 hours to charge the 12 cell battery from 0 to 100% on both AC and DC power, and 8 hours for the 24 cell battery.

The Bottom Line

Even though it’s small and light, the G2 comes with a mobile cart for even easier travel. The moble cart itself is quite easy to manuever, so no getting stuck in crowds or on bumpy terrain. The Inogen One G2 is everything a portable oxygen concentrator should be – it’s small and light, it can deliver a higher dose of pulse dose oxygen, and the battery duration is great. The G2 is approved for in flight use by the Federal Aviation Administration, for any flight to or from the United States. All around, the Inogen One G3 is a spectacular portable oxygen concentrator for those who need pulse dose oxygen up to the setting of 6.
