The Powershell ® with new extended life battery. 

 The PowerShell just got better with the NEW Extended Life Battery!
 
The PowerShell turns your Z1™ into a totally self-powered cpap solution perfect for travel, camping, or just battery backup while at home. Just insert the Z1™, put in a Extended Life Battery and you can get a full night's sleep of cord-free cpap. This is the only fully integrated cpap battery available.

 The NEW Extended Life Battery has twice the battery capacity of the original Overnight Battery, so even at the highest settings (20 cmH2O, Z-Breathe 3) cpap therapy should last 8.9 hours.* With lower pressure settings you should get even longer therapy.

 * Results were obtained via bench testing under simulated operating conditions. Actual run time may vary due to machine settings, machine pressure, and personal breathing. Lower pressures will result in longer battery operating times.
