Inogen One G3 vs. SeQual Eclipse 5 Concentrator Comparison

There are many benefits of receiving oxygen therapy in the form of a portable oxygen concentrator. If you’re having shortness of breath, feel some strain on your heart, or have a lack of energy doing the things you love, oxygen therapy can help.

But when it comes to choosing an oxygen concentrator, it can seem overwhelming to discover which product is best for you. Today we’re providing an overview of two of the many oxygen concentrator products we offer: Inogen One G3 and SeQual Eclipse 5. Although both are quality choices in oxygen concentrators, they have a few key differences. Learn about similarities and differences between the Inogen One G3 and SeQual Eclipse 5.

Inogen G3 and Eclipse 5 Oxygen Flow Settings

When it comes to oxygen flow delivery, the Inogen One G3 and SeQual Eclipse 5 have different offerings. The Inogen One G3 has a pulse dose setting of 1-5 and delivers a maximum oxygen output of 1050 ml per minute of 90% oxygen for newer models or 840 ml per minute of 90% oxygen for older versions.

The SeQual Eclipse 5 offers both a pulse dose and continuous flow setting. On pulse dose, you can go from a setting of 16 to 192 ml in 6 settings, and a continuous flow setting of 0.5 to 3 liters per minute. The SeQual Eclipse 5 has a maximum oxygen output of 3000 ml per minute.

Summary: Although there are many options for each depending on the setting you choose, keep in mind that the Inogen One G3 only has the option to deliver in a pulse dose method, while the SeQual Eclipse 5 delivers both pulse dose and continuous flow.

Inogen One G3 vs. SeQual Eclipse 5 Concentrator

Weight and Size

The Inogen One G3 is a lightweight, portable concentrator option. With the 8 cell battery, this product weighs less than five pounds. With the 16 cell battery, it comes to 5.7 pounds. The dimensions of this model are 8.75 inches wide, 3 inches deep, and 8.25 inches tall.

The SeQual Eclipse 5 is much larger than the Inogen One G3, but this allows for continuous flow — in addition to its pulse dose settings. The unit itself weighs 15 pounds, and the battery adds 3.4 pounds — making it 18.4 pounds total.

Summary: The SeQual Eclipse 5 might weigh more than the Inogen One G3, but the SeQual option does offer two options for oxygen, both continuous flow and pulse dose.

Battery Life

Battery life for a portable oxygen concentrator is vital, whether you’re on-the-go or at home using your oxygen. When comparing oxygen products, it’s important to pay attention to the length of battery life each product offers, as well as how long it takes to charge the unit — although most units take anywhere from two to five hours to charge.

The Inogen One G3’s battery life depends on the setting you’re using on your concentrator. It also depends on which battery you choose, whether it’s the 8 cell or 16 cell battery. To get an idea of the battery duration, setting 1 provides an average of 4.5 hours of use with the 8 cell battery, and 9.5 hours of use with the 16 cell battery. And if you’re using setting 5, you’ll be provided with an average of 1.7 hours of use with the 8 cell battery, and 3.3 hours of use with the 16 cell battery. To charge the 8 cell battery, it takes an average of 2-4 hours. The 16 cell battery takes an average of 5-8 hours to charge.

The SeQual Eclipse 5 battery is a little easier to understand in terms of how it charges. Depending on your flow level, whether you’re using continuous or pulse dose, it takes an average of 1.8 to 5 hours to reach 80% battery charge. The battery during the continuous flow option will last approximately two hours (at 2 LPM), and it will last an average of 5.1 hours at 2 LPM.

Summary: As a side-by-side comparison, the Inogen One G3 will average 4 hours of battery life (with the 8 cell battery), and the SeQual Eclipse 5 will average 5.1 hours of battery life — both during a level two pulse dose mode.
