Description
The USB Charger Doctor is a tool for measuring the working voltage and current output of any USB port and project. This blue plastic dongle connects to a USB device and allows data lines to travel through. A 0.05-ohm resistor is connected to the power pin which is used to measure the current draw. The digital display of the module rapidly reads the numbers for testing items like chargers, cables, and mobile phones.
You may use this device with an input voltage of 3.5-7VDC (most USB devices seem to hang around 4.75 to 5.25) and a current of up to 3A. Every 3 seconds or so, it switches between voltage and current readouts. It's a great tool for testing USB devices, determining load levels, and troubleshooting battery chargers and boosting converters.
