If you’ve lost your IDVisor Z22 power supply, here is one which we recommend available on Amazon for less than $6.00
You’ll need one that is 12 Volts DC (Direct Current), center positive (this means the inside part of the plug is plus), with at least 1 Amp or 1000mA of current.
The plug is 5.5 mm in diameter with a center hole that is 2.1 mm.
