Thank you for viewing! Easy motor break-in! Safe circuit within the case!! ⚫︎Connect to a USB adapter and adjust the voltage with the knob. ⚫︎LED: Green 　Input voltage: DC5v 　Output voltage: 1v〜24v (130 motor: DC0.6v〜5v) ⚫︎Outputs from USB 5V to approximately 0.6V〜25V (no load) 　A unit that can handle both step-down and step-up! ⚫︎The included harness is handmade. Solder uses aluminum solder. Please refer to the photos for the length. It may vary by ±1.5 cm, but the red and black wires are generally the same length. The voltage display is a guide, so please use measuring instruments if necessary. Brand new, unused, and tested for operation. Not recommended for those seeking perfection or who are overly sensitive.
