The PowerShell® with Extended Life Battery | Z1 & Z2 Compatible
 
The PowerShell is the first fully integrated power solution for cpap users that need a totally portable, integrated power source. It is small enough to fit in the palm of your hand but has enough power for a full night of cord-free cpap. The Extended Life Battery lasts twice as long as the original Overnight Battery. So even at the highest settings (20 cmH2O, Z-Breathe 3) it should provide 8.9 hours of cpap therapy. The PowerShell is compatible with both the Z1 and Z2 CPAPs.
Soft, padded 2mm neoprene skin over a solid plastic skeleton ensures a secure fit
Surrogate power plug for built-in charging using the standard Z1/Z2 power adapter
Insert the Extended Life Battery module and the Z2 or Z1 to create an integrated form-factor.
Approved by the FAA for in-flight use.
Factory installed upgraded firmware ensures complete charging of Extended Life Battery.
