This week a USB power device has been discovered to be absolutely terrible by a device tester by the name of Clive Mitchell. He's in the business of testing things like these, and he's smart about how power works. And how it's not supposed to work. And how a USB device like the one you're going to see should NOT be lighting up a light bulb like you're about to see. This is why we can't have nice (off-brand) things.
