The Extended Battery for the SimplyGo Mini is just one of the two battery options available for this portable oxygen concentrator. The Simply Go Mini is itself a powerful portable model for how small it is, and its extended battery is what gives it the power to provide you with even more time to go where you need to go.

The  extended lithium-ion battery lasts up to 9 hours on the pulse setting of 2. This is ideal for oxygen therapy patients who need to use oxygen therapy for many hours out of the day, or all day. Patients can enjoy using a lightweight, portable oxygen concentrator for exercise and short trips without having to worry about charging again for 9 hours.

It takes up to 8 hours to charge the extended lithium-ion battery from 0 to 100%. It can be charged with AC power via the AC power cord, or in a motor vehicle on DC power with the DC power cord. It can also be charged with the SimplyGo Mini external battery charger so that one battery can be charging while the other is being used in the unit.

The standard battery is very lightweight at only 952 grams and is 7.9 inches wide x 3.6 inches deep x 1.9 inches high. It's easy to carry multiple extended SimplyGo batteries in the accessory bag, or in the SimplyGo Mini backpack, which makes it easy to replace a depleted battery with a charged one while on the go.
