Oh no, what is going on with my USB device, it's getting HOT. Queue the USB Charger Doctor. Thanks to this little gadget you will be able to watch and care for your USB device or powered projects.

The Doctor plugs between a USB device and passes the data lines through. The digital display will instantly read the numbers out for testing devices such as chargers, cables and mobile phones.

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.
