The Inogen One Lithium Ion Battery is the perfect power source for trips to the store, seeing a movie, or a dinner out with friends. Having an extra battery or two on hand is a great way to make sure that you can get up and go whenever you want.
This battery can be charged while in the InogenOne system (when connected to an AC or DC power supply), or when outside of the InogenOne system using the Inogen One External Battery Charger.
