Zen-O Battery Charger Overview:
For many oxygen users that depend on their portable oxygen concentrator, battery charging can be a pain. For the Zen-O and Zen-O Lite portable oxygen concentrator the external battery charger can be a huge help. While you are using your Zen-O you can be charging an additional battery at the same time.
Simply place the battery in the charging port and connect your charging port to a wall AC outlet. The battery will charge to a full status and will be ready for use when you need it. This is a great way to make sure that extra batteries remained charged and ready for use.
