How it works

Connect a USB power source to the USB input, attach your device to the DC output, and use the built-in selector to choose between 9V or 12V. The digital display provides immediate feedback on the output, helping you verify compatibility and monitor performance at a glance.

Ideal use cases

  • Testing and verifying USB power banks and chargers
  • Powering small devices that require higher voltage from a USB source
  • Prototyping electronics projects where a stable DC supply is needed
