Inogen One G5 Double Battery

The second you receive your Inogen One G5 portable oxygen concentrator you will immediately begin to feel your freedom being returned!

Now you can finally ditch those heavy and cumbersome oxygen tanks, for a mobile friendly supplemental oxygen concentrator.

However, if you want to make sure you can attend those family gatherings, card games with friends, or to be able to freely do what you want like before having to use medical oxygen, you are going to need at least one Inogen One G5 rechargeable battery!

If you really want to take advantage of your newly restored freedom, then look no further than the double battery for the Inogen One G5.

Find a Battery Life That Meets Your Demand

Not all oxygen users operate their machine the same way, and what I mean by that is battery life is simply not a one size fits all!

Which is exactly why you have the ability to chose from 2 sizes of battery options so you can find one that perfectly matches your lifestyle needs.

If you are looking to enjoy the lightest overall package of 4.7 pounds with a shorter battery life, check out the Inogen One G5 single battery here.

However, if you are a power user and refuse to be stuck at home like you once were, then you are going to definitely want to opt for the G5 double battery.

Although the G5 double battery increases the overall weight of your Inogen One G5 by a pound, bringing it to 5.7 pounds, you are able to enjoy up to 10 hours of portable operation on a pulse setting of 2.

That’s double the battery life of the Inogen One G5 single battery on a pulse setting 2.

Plus if you are wanting to travel, FAA requirements state that you have 150% of flight time in battery life. So if you are taking a 5 hour flight, you will need up to 10 hours of battery life, which is exactly what you’ll get using the G5 on a pulse setting of 2!

Battery Life:

Pulse Flow Rate Battery Life
1 Up to 13 Hours
2 Up to 10 Hours
3 Up to 7 Hours
4 Up to 5 Hours
5 Up to 3 Hours and 48 Minutes
6 Up to 2 Hours and 45 Minutes

Charging Options That Won’t Hold You Back

When it comes to charging your portable oxygen concentrator, it simply makes sense to develop charging options that match the freedom that is provided by the Inogen One G5.

Enjoy restriction free charging of your Inogen One G5 double battery that won’t interrupt your day to day activities!

With the Inogen One G5 you are able to charge the double battery in 3 ways, which include the AC power supply, DC power supply, and the optional external battery charger.

When you’re at home relaxing or doing chores and you look down and notice your Inogen One G5 double battery is running low, you will simply reach for the included AC power supply. All you will need to do is plug one end into the G5 and the other end into a nearby wall outlet and your battery will begin to charge.

The second you do that the AC power supply will begin to recharge your double battery in up to 8 hours. However, keep in mind that if you are using your G5 while charging, the overall charging time will be increased.

When you start to enjoy your newly restored freedom with the Inogen One G5, you won’t always be at home near a wall outlet when it comes time to recharge your Inogen One G5 16-cell battery.

But there is no need to worry, Inogen has you covered with the included DC power supply.

This lightweight and handy cord allows you to seamlessly power and charge your Inogen One G5 in your car, truck, SUV, RV, or boat as long as it has a standard cigarette lighter outlet.

And just like with the AC power supply, you can use your Inogen One G5 while charging in your vehicle but this will extend the overall charging cycle.

If you are a power user and choose to purchase more than one battery, then the optional Inogen One G5 external battery charger should definitely be an accessory that you consider purchasing!

Thanks to this compact external battery charger, you are able to seamlessly charge either the Inogen One G5 single battery  or the double battery externally from the unit.

Allowing you to use one battery to power the G5, while you have another battery on the side charging up for interruption free operation of your Inogen One G5.
