Our take on the External Battery Charger w/ Power Supply for G3 Oxygen Concentrator

This is Inogen's external charger kit for the One G3 portable oxygen concentrator. It charges the G3's single and double batteries outside the unit, so a spare battery can top up while another runs the concentrator. It includes the charger, power supply and AC cord. It suits G3 owners who keep a second battery and want it ready without tying up the concentrator.
