PowerShell and Battery Questions

No, you cannot run your Z1 or Z2 on a DC mobile adapter however, it can be used to charge the PowerShell. We cannot guarantee the mobile adapter will function with all cars, as battery voltage isn’t uniform.

Once the battery is fully charged, please disconnect your Z1/Z2 machine from your PowerShell and remove the battery from the PowerShell, or it will slowly drain the battery over the course of 2-3 days.

Make sure you hear a clicking noise when inserting the Z1 or Z2 into the PowerShell. If it is still not charging disconnect the Z1/Z2, battery, and power supply and reconnect. Proceed to recharge your unit again for 10-12 hours. If it is still not holding a charge it will need to be sent in for a return by the provider you purchased your unit from. Please keep the following information in mind after charging your Power Shell:

  • Disconnect the battery from the PowerShell after a full charge to prevent the battery from slowly draining within a 2-3 day period.
  • The battery needs to be charged for 10-12 hours to ensure a full charge.
  • The bars of battery life on the LCD screen need to be full, and not blinking.
  • The PowerShell battery will not charge while it is operating the Z1/Z2 for treatment. The battery must be charged between treatments.
