Expand your use of the Inogen One G3 portable concentrator by upgrading to the 16-cell battery, delivering twice the battery life of the 8-cell battery. You will see that the number of charge cycles will decrease drastically. On position 2, the 16-cell battery will produce additional oxygen for up to 8 hours.

That kind of battery life means you can run errands and still have battery life left over! Charged with the AC power supply, which is for stationary home use, or in your vehicle with the DC power supply through the cigarette lighter output. When either power supply is connected, the G3 automatically charges the battery and all functionalities are available.
