This is a USB Step Up Conversion Kit 5v-12v.
Compatible with any mobile cell phone charger with a usb port.
Takes the standard USB (5 V) and steps it up to 12 VDC to work with your Portable turntable. This has been tested and confirmed to work with both Vestax HandyTrax and all Numark PT01 Turntables.
For those who have modded tone arms and start / stop button: The cable has a step up transformer that converts the voltage from 5V USB to 12 VDC, and the internal rectification circuit is then changed to 9VDC. It will power your set up.
For best results use batteries with the specifications below:
