Test/Measure/Experiment

You can use this device from 3.5-7VDC input voltage (although most USB  devices tend to hover around 4.75 to 5.25) and up to 3A of current. It  flips between voltage and current readouts every 3 seconds or so. It's a  very handy tool for testing USB devices, checking load levels and  debugging battery chargers and boost converters.
