PowerShell with Extended Life Battery Module for Z2 Series CPAP Machines

For nights away from fixed power add a PowerShell with Extended Life Pack to your Z1 or Z2 Series CPAP Machine. The PowerShell provides an innovative, integrated solution, merging the machine and battery in one convenient package. It is small enough to fit in the palm of your hand; but has enough power to give you truly restful nights of sleep therapy under the stars, on the road, or in the air!
