Oxygen Battery Charger Buying Guide

Oxygen Battery Charger Buying Guide

A battery charger is an extremely important thing to have if you have a spare battery that you will be using a back-up for your portable oxygen concentrator. The point of having a portable oxygen concentrator is that you don't need to sit still while you are using it.

Not all of our portable oxygen concentrators will require a spare battery or a battery charger. Some concentrators do not have a battery that can be changed out and recharged externally. For example, the Lifechoice can be recharged by plugging the machine itself into a power source.

We know that having an extra battery and a battery charger is extremely important, which is why our external battery chargers are reasonably priced. Each battery charger is designed to specifically fit the battery for each portable concentrator.

The Best Way to Use Your Battery Charger


The best way to use your external battery charger, is to carry it with you as you travel and leave it in your hotel room or by your power source. When one battery has been drained, you take it out and replace it with your fully charged spare battery.

Carrying a spare battery with you ensures that you have plenty of time while you are out and about or traveling, to do the things you want to do and go where you want to go. If you have a spare battery, you will also need a battery charger to power up one while you use the other.

You should always check with an airline at least 48 hours in advance, but many airlines require that you bring at least one more fully charged battery with you on your flight. Concentrators such as the Lifechoice that cannot be charged externally are still FAA approved and should still be allowed on the flight.
