The Only Option for Simultaneous Charging 
 The Inogen external battery charger is your ticket to no longer having to wait for your Inogen batteries to recharge to use your oxygen concentrator. This is because the external battery charger allows for patients to run a battery in the G3, while having an additional battery on the side charging. This will allow for seamless transitions, once a battery is fully depleted remove it from the unit and swap it out with a fresh fully charged battery. 
 
Setting Up is Simplistic  
Setting the external battery charger up is simple, just plug the included power cord into the back of the charger and plug the wall adapter into any of your homes power outlets. Recharging your batteries have never been faster, a fully drained battery depending on the size will take anywhere between 3 – 6 hours.
