Inogen is one of the most recognizable names in the oxygen industry and the Inogen One G3 is a big reason why. Weighing in at 4.8 pounds and offering up to 8 hours of battery life, the Inogen One G3 has been one of the most popular portable oxygen concentrators on the market for over two years!
Inogen One G5 Single Battery
The Inogen One G5 Single Battery is the same battery unit that comes with your G5 Portable Oxygen Concentrator and it's the smallest battery offered for the device. Whether you're looking to replace your current battery or you just want a backup battery, this may be a great option for you.
Easy Storage and Portability
If you already own an Inogen One G5 Portable Oxygen Concentrator, you know how convenient the G5 Single Battery is. It's light enough that it doesn't at significant bulk to your device but it's powerful enough to afford you up to 6.5 hours of battery life on one charge.
The rechargeable lithium-ion battery found in your device can be charged while it's attached to your G5 Portable Oxygen Concentrator or with an external battery charger.
Due to its small form factor, the G5 Single Battery is great as a backup battery pack if you think you might use up your other battery while on the go. If you have a G5 Backpack, this battery will fit snuggly in an accessory pouch without adding a whole lot of weight.
If you're planning a trip or you know you'll be away from home for an extended period of time, you can fully charge your G5 Single Battery and simply attach it to your oxygen concentrator when it runs out of juice.
