Setup & Use 📘

Connect the AC power supply to the charger unit and plug it into a standard wall outlet. Slide your Inogen G4 battery into the top tracks of the charger until you hear a click. The red/orange light will indicate the battery is charging. When the light turns green, the battery is fully charged and ready for use. To remove, press the release latch and slide the battery off the unit.

Recharge Your Freedom Away from the Machine

Don't let your schedule be dictated by a power outlet. The Inogen One G4 External Battery Charger gives you the ability to "hot-swap" your power sources effortlessly. By charging your extra batteries outside of the machine, you can effectively stay cordless for 24 hours or more, keeping your Inogen G4 small and light while your spares replenish in the background.

Parallel Charging Capability

One of the main barriers to 24/7 mobility is waiting for your battery to charge inside the machine. This external charger removes that obstacle by allowing you to breathe normally with your concentrator while a second battery reaches full power separately. It is the perfect tool for long-haul travel, where having multiple charged batteries is a safety requirement for airline flights and extended excursions.

Intelligent Energy Monitoring

Equipped with an advanced internal microprocessor, the G4 charger does more than just supply power. it communicates with the battery’s built-in sensors to deliver the most efficient charge possible while preventing overheating or overcharging. This precision ensures that your expensive medical batteries remain healthy and maintain their maximum capacity for years of use.

Sleek, Travel-Oriented Profile

Designed to mirror the ultra-light philosophy of the Inogen G4, this charger features a micro-footprint. It is barely larger than the battery itself and features a secure, click-in latch system. Its durable casing is built to withstand the bumps of transport, and the universal voltage compatibility makes it a seamless companion for international travelers visiting Europe, the UK, or the USA.
