About The Inogen One G5 External Battery Charger

Fortunately, today’s technology offers different portable oxygen concentrators that allow patients with independence and mobility. Most patients’ favorite product right now is the Inogen One G5 Portable Oxygen Concentrator!

This latest Inogen model can accompany you on your daily activities and trips from all parts of the world. You wouldn’t have to think about your battery running low because this unit offers an external battery charger.

The Inogen One G5 External Battery Charger allows you to charge your unit’s battery externally — not when it’s connected to the unit. Note that this external charger can only charge one G5 battery at a time, whether you’re using an Inogen One G5 single or double battery.

Like the unit itself, the Inogen One G5 external battery charger is also easy to carry due to its lightweight and compact feature. If you think your Inogen One G5 unit needs an external charger, feel free to read through this article about the Inogen One G5 external battery charger!

Inogen One G5 External Battery Charger Benefits And Features

The design for the Inogen One G5 external battery is primarily for increased functionality. This particular Inogen One G5 accessory is an excellent option for oxygen patients who already have extra batteries.

Aside from the fact that it helps extend your oxygen concentrator’s battery life and usage, it still has more features to offer. Below are the things you must consider before buying the G5 external battery charger!

Suitable for both single and double batteries

It doesn’t matter whether you use a single battery (8 cells) or a double battery (16 cells) to operate your Inogen One G5 because the external battery charger is compatible to work with both.

This battery charger recharges G5 batteries in just a few hours. A fully depleted Inogen One G5 POC’s single battery can charge at approximately 4.5 hours, while a fully charged Inogen One G5 POC’s double battery is under nine (9) hours.

The Inogen One G5 external battery charger can also recharge the G5 units when powered by a DC power cable and AC power supply. It provides convenience for patients who own G5 single and double batteries!

With LED Indicator light for battery status

It’s crucial for oxygen concentrator users to check the battery status or charging time. Fortunately, the Inogen One G5 external battery charger flashes the battery charging time for single and double batteries through LED indicator lights.

This prevents any complications regarding battery mistracks and usage. You wouldn’t need to set the alarm to know whether the device has finished charging or check the battery status constantly. The LED indicator light does all those work for you!

Benefits patients with multiple batteries

The External Charger is an excellent option for patients with extra Inogen One G5 batteries. This allows both batteries to be rotated out of your unit while keeping them charged at all times.

For instance, you may charge one battery through your AC power cord while the other is through your external battery charger. This is very fortunate for patients who have errands the next day. They can bring two fully charged batteries with them.

Safe and easy to bring for air travels

You can bring your Inogen One G5 external battery effortlessly along with your G5 portable oxygen concentrator on aircraft travels. Aside from the fact that this external battery charger is FAA-approved, it weighs only approximately 0.85 lbs. It certainly wouldn’t take too much space and weight on your luggage.
