Please note that it can take up to 8 hours to charge a fully depleted battery. The battery will charge when the AC adapter is plugged into the powershell and wall outlet, but only when the Z1™ is in ‘standby-mode’- meaning when the device is plugged in but NOT in use/ being used for therapy.


When your battery has a full charge it will be displayed on the Z1 LCD screen.


If the Z1 appears to stop charging (battery stops blinking during charge cycle) we recommend disconnecting the powershell, battery, and Z1 device completely from each other and then re-connecting all components. If this does not solve the problem, or if the issue presents itself again, please contact your supplier for further support.
