Battery Charging Tips

The battery charges using the AC Power Supply or DC Charging Cable. Charging a fully depleted battery takes approximately 4 hours. Charging the battery while using the machine will take longer than 4 hours. The OPTIONAL External Battery Charger can be purchased separately to charge batteries, not in use.

PLEASE NOTE: The External Battery Charger doesn't connect directly to the Inogen G4 and isn't intended to supply power to the Inogen G4. It's meant for charging batteries only.

Where is the Battery Charge Displayed?

There is an LCD screen on top of the Inogen G4 that displays the battery level. The battery level is displayed as a percentage showing the remaining charge.

PLEASE NOTE: As of June 2018, the Inogen G4, as well as the Single and Extended 8 Cell Batteries are approved for use while in-flight on aircraft, according to FAA Regulations. While the FAA has approved the Inogen G4 for in-flight use, airlines can pass internal regulations that can change quickly. In June 2018, we know of no airline that prohibits these devices.

To be safe, it's important to confirm with the airline that the device is still acceptable for in-flight use at least 48 hours before flying, or before purchasing a ticket with that airline.
