Lightweight & Compact Portable Oxygen Solution

Oxygen concentrators are self-contained oxygen therapy systems that concentrate oxygen from the surrounding ambient air. Portable oxygen concentrators have revolutionized oxygen therapy, and Inogen continues to innovate with its latest design – the Inogen One G4. Weighing in at a mere 2.8 pounds (including battery), the Inogen One G4 is the lightest and most compact oxygen concentrator design produced by the California-based company.

About the size of a thick hardcover book, the Inogen One G4 makes for a discreet oxygen source. The G4 concentrator easily tucks away into its complementary carrying bag with shoulder strap for an incredibly convenient portable oxygen system. No more heavy tanks or hard-to-maneuver rolling carts slowing you down, instead just slide the strap over your shoulder and off you go!

Three Oxygen Flow Settings & Breath Detection Alert

While the pint-sized stature of the Inogen One G4 makes it practical and convenient, that doesn’t mean it’s underpowered. The sturdy G4 is designed for 24-hour use and delivers oxygen therapy with three different flow settings. The G4 oxygen concentrator also offers advanced features, like its Breath Detection Alert Mode. Once enabled, the Breath Detection Alert triggers audible and visual signals after 60 seconds without a breath detected. The Inogen G4 then enters auto-pulse mode until another breath is detected, with a flashing yellow icon on the LCD screen also indicating the alert’s activation.

Battery Power with Portable Charging Options

The Inogen G4 sources a lithium-ion battery pack for cordless oxygen therapy, with the battery recharging itself when connected to the AC power supply or DC charger. A fully charged battery can deliver 4.5 hours of oxygen therapy and takes 5 hours to recharge from full depletion. Extra battery packs can extend your cordless oxygen experience, with an accessory Inogen G4 Double Battery offering up to 2.7 hours of therapy on a single charge.

The Inogen One G4’s DC charger, which comes as standard equipment along with the AC power cable, provides mobile charging options. The DC power cable plugs into 12-volt power sources for use in a car, truck or RV. The AC power supply automatically adjusts to multiple input voltages (100 to 240V), allowing it to be used with most power sources across the globe. And international travelers, as well as those flying closer to home, will appreciate the Inogen One G4’s approval by the FAA for in-flight use.

Easy-to-Read LCD Screen & Intuitive Menu

The Inogen One G4’s easy-to-use design extends to its LCD screen and control panel. Patients won’t need to fuss with overly complicated menus or instrumentation. The G4’s intuitive interface features a simple On/Off button and two buttons to adjust the three-position Flow Setting, with another button engaging the Breath Detection Alert. Two small indicator lights signal when the system is running properly (green), changing in operating status (yellow) or alerting the patient (flashing yellow). The easy-to-read LCD screen displays flow setting and power status, including the percentage of remaining battery duration, so patients know when to swap out batteries or find power source to recharge.

Battery Duration

Setting of 1 - 8 Cell Battery: 5 hours, average

Setting of 3 - 8 Cell Battery: 2 hours 30 minutes, average
