The USB Charger Doctor is a handy tool for measuring the working voltage and current output of any USB port and project. Encased in blue plastic, this dongle connects to a USB device and allows data lines to pass through while measuring current draw via a 0.05-ohm resistor connected to the power pin. Real-time numbers for testing devices like chargers, cables, and cell phones are displayed on its digital display.
