USB to 5.5mm/2.1mm DC Booster Cable - 9V or 12V Output

This cable is kinda fascinating - it has an integrated boost converter, so you can plug it into any USB port (from a computer, battery pack, etc), and it will give you a higher DC voltage! It's a handy way to power a 9V or 12V device. Unlike our other 'USB booster' cables, this one comes with a fancy lil display and a switch so you can select between 9V or 12V output and the voltage will be indicated. You can draw about 1A from 9V setting or 750mA from the 12V setting.
