Inogen External Battery Charger with Power Supply

Charges Inogen portable oxygen concentrator batteries independently of the concentrator unit, ensuring a spare battery is always ready.
The charger and power supply are designed to be compact and lightweight, making them easy for travel and use at home.
Features a simple slide-in mechanism for the battery and LED indicator lights to show the charging status (e.g., solid red for charging, solid green for full charge).
It includes a universal AC power supply and input cord, compatible with 100-240 VAC for worldwide use (a plug adapter may be needed for certain regions).
Users can charge one battery with the external charger while using a second battery in the concentrator unit.
