Oxygen users travel and move around just like we all do and that is why we have options to make that easier and more of a reality. Oxygen Concentrator power accessories, including AC/DC adapters, batteries, power cord, etc etc you name it and chances are we have it. Maybe you just need a replacement power cord for the one you might have lost? No worries, we may have one that you need.
There are going to be those times where you simply need a replacement battery for you oxygen concentrator internally as the one you have is on it's last legs so when that time comes (which may be now) you don't want to wait until the last minute so prepare yourself in advance and be worry-free
