One of the most important things about your portable oxygen concentrator are the batteries. Purchasing an external or replacement battery, besides the one that came with your concentrator, is important. Having an extra, fully charged battery with you on trips is always a good idea. At full charge, your battery should give you enough time to explore, travel and take a shopping trip, untethered to an external power source.
The battery charger is a great option for people who have extra concentrator batteries as it allows all batteries to be kept fully charged at all times. Batteries will recharge in the concentrator whenever it is connected to AC or DC power. In addition batteries can be recharged outside of the concentrator using the charger.
