Inogen External Battery Charger with Power Supply

The Inogen External Battery Charger with Power Supply is a compact, portable accessory designed to charge spare Inogen lithium-ion batteries independently of the main oxygen concentrator unit — ensuring a fully charged backup battery is always ready when you need it. Includes a universal AC power supply compatible with 100–240 VAC for worldwide use.

Charge a Spare While You Use the Concentrator
The key advantage of the external charger is the ability to charge one battery with the external charger while simultaneously using a second battery in the concentrator — eliminating downtime and ensuring continuous, uninterrupted oxygen therapy throughout the day.

Simple Slide-In Operation with LED Status Indicators
Features a straightforward slide-in mechanism for easy battery insertion. LED indicator lights provide clear charging status at a glance:

• Solid red — battery is charging
• Solid green — battery is fully charged

Universal AC Power Supply — 100–240 VAC
Includes a universal AC power supply and input cord compatible with 100–240 VAC, 50–60 Hz — suitable for use worldwide. A physical plug adapter may be required for non-North American outlets, but no voltage converter is needed.

Compact & Travel-Friendly
Designed to be compact and lightweight for easy packing alongside the concentrator — ideal for extended travel, overnight stays, or any situation where access to the concentrator's charging port is limited.
