The G4 External Battery Charger provides a convenient way to recharge additional Inogen G4 single and double batteries outside the oxygen concentrator. It is a practical accessory for users who want to keep extra batteries charged and ready for use.
As a result, you can charge an additional battery separately while using another battery in your Inogen oxygen concentrator.
Fast Battery Charging
The external charger can fully charge compatible batteries outside the G4 unit. For example, a fully depleted G4 single cell battery can charge to full in approximately 2.5 hours.
Additionally, a fully depleted G4 double cell battery can charge completely in under 5 hours.
Therefore, the external charger provides a convenient option for preparing additional batteries before travel or daily activities.
Charge Batteries Outside the Unit
With the G4 External Battery Charger, you can charge your battery without placing it inside the oxygen concentrator. This means you can keep one battery ready for use while charging another battery separately.
Furthermore, this can be especially convenient when you own multiple batteries and want to prepare them before heading out.
AC Power Supply Included
The charger includes an AC power supply, so you have the necessary power connection for charging compatible batteries.
As a result, the charger provides a simple and convenient charging solution for your additional Inogen G4 batteries.
Convenient for Travel
The Inogen One G4 External Battery Charger is a useful accessory for users who regularly travel or need additional battery capacity. By charging extra batteries in advance, you can have a charged battery available when your current battery becomes depleted.
In addition, the external charging design helps make battery management more convenient for everyday use and travel.
