Z2 Power Shell with battery

The PowerShell integrates the Z2 with a rechargeable lithium-ion battery so you can take your CPAP anywhere, even where there is no electricity. A full night's use for most users. Enjoy a peaceful night of CPAP therapy. Traveling abroad? The power automatically adjusts from 100 to 240 volts. All you need is the appropriate plug adapter for the country you're visiting. A soft, padded 2mm neoprene shell over a solid plastic skeleton ensures a secure fit.
