This MicroB USB Cable with Voltage and Current Meter is your quick and easy solution to measure USB output voltage and current. Plug it into a USB port and it will let you know the voltage on the USB power pins. Once a device is plugged in, it will instantly display the working current. Wtih its compact form factor, you can take it with you anywhere to test the USB devices, checking load levels and debugging battery chargers and boost converters. The only down side is that once the device starts charging, the display will not show the voltage anymore, just the current draw.
