PocketPD Tiny Bench Power Supply. LCD Variable Test Adjustable CNC DC CC mini

About this deal

The PocketPD is a compact bench power supply powered entirely via USB Type-C, designed to pair with any modern USB-C charger or power bank to deliver a wide range of adjustable output voltage. It leverages the Programmable Power Supply (PPS) mode built into USB Power Delivery 3.0, which lets the device request precise voltage and current directly from the charger, enabling a very compact and lightweight design with no need for a bulky built-in transformer. It supports adjustable voltage from 3.3V to 21V and current from 1A to 5A , with both constant voltage (CV) and constant current (CC) modes, as found on full-sized bench power supplies. Controls are kept deliberately simple with physical knobs and buttons, which helps ensure reliable operation when you need it most. Built-in protections against short circuits, reverse current, and fly-back diode issues make it safe for use with sensitive electronics. It is well suited to electronics hobbyists, students, engineers, and makers who need a capable, portable power source for testing, prototyping, or field use without carrying heavy bench equipment.
