The USB Charger Doctor is a handy diagnostic tool designed to measure the working voltage and current output of any USB port or powered project. Housed in a blue plastic case, this compact dongle connects directly to USB devices and allows data lines to pass through while measuring current draw using a 0.05-ohm resistor connected to the power pin. Real-time voltage and current readings are shown on its digital display, making it ideal for analyzing devices such as chargers, cables, and mobile phones.
