The eQuinox is the lightest continuous flow portable oxygen concentrator to offer up to 3.0 LPM of oxygen at a mere 14 pounds.

The eQuinox stands just 10.6” W x 7.4” D x 13.6” H. Its small size makes it easy to store and it fits underneath the seat in front of you on an airplane without taking it off the travel cart.

The eQuinox gets great battery life for a continuous flow unit. On a pulse flow setting of 2 you can get up to 5.94 hours of use on a single charge. On a continuous flow setting of 2.0 LPM you can get up to 2.75 hours of use on a single charge.

There are 3 different ways you can recharge your battery; the AC power supply, the DC power supply, and the optional external battery charger. The AC power supply and external battery charger will be the most efficient options, as they don’t have any restrictions. The DC power supply will only recharge your battery if you are using your concentrator on an oxygen setting of 4 pulse or 2.0 LPM or lower.

SeQual states that your battery will take anywhere from 1.5 to 3.5 hours to reach 80% charge depending on if you are using the concentrator while you charge and what setting you are using your concentrator on.

The SeQual eQuinox offers both pulse flow and continuous flow oxygen delivery. It offers pulse flow settings 1-9 and continuous flow settings 0.5-3.0 LPM.

The eQuinox registers at 45 decibels on a setting of 2.0 LPM. This is a little bit louder than other concentrators, but not my much. It’s still quieter than a running refrigerator or a normal conversation so you don’t have to worry about it being invasive.

The eQuinox has an operating altitude range of 0-13,123 feet. If you go above 13,123 feet the concentrator’s performance may suffer.
