The Philips Respironics Battery Kit is an ideal power solution for the DreamStation and System One sleep therapy device users. It combines the convenience of the lightweight CPAP travel battery with the security of an Uninterruptible Power Supply (UPS). In case the power goes out, the battery pack’s UPS helps reduce any therapy disruptions through the night. Connecting the battery kit to the device’s power supply keeps it charged and ready to go. This is the lightest and smallest battery pack ever, weighing only 2.25 pounds. This makes it conveniently portable so users can have CPAP therapy while they are away from home. The battery pack connects to the device’s power supply to reduce the number of cords needed to travel. Because of its lightweight and compact design, this battery kit is FAA approved to be able to travel on airplanes (90W lithium-ion battery pack). It provides 14 hours of battery life.
