The Inogen One G4 includes two convenient shoulder strap attachment points for easy portability, and a barb section at the top for your cannula. There’s a USB port, a particle filter, and two exhaust vents on the left and right side. It features a user interface panel that is simple to operate with an LCD display. On this panel, you can increase or decrease flow settings, and it includes an audible alert button, alert light, and a breath detection light. It comes with a single battery that provides up to 4.5 hours of life and is fully rechargeable in a couple hours. A double, extended life battery is also available for even longer use while on the go. The new G4 is half the size, and 42% lighter than the Inogen One G3. It is nearly 60% smaller than the Simply Go Mini and delivers the highest oxygen output per pound of any oxygen concentrator in the U.S. homecare market.
