The Philips Respironics SimplyGo External Battery Charger is a great option for people who have extra portable oxygen concentrator batteries, as it allows all batteries to be rotated and kept fully charged at all times. Batteries do not have to "take turns" charging in the SimplyGo portable oxygen concentrator.

The Respironics SimplyGo External Battery Charger will recharge one battery at a time as well as recalibrate the battery's fuel gauge. Fuel gauge recalibration enables the battery to calculate a highly accurate estimate of remaining battery life, shown on the battery fuel gauge, even as the battery ages.
