I like gadgets, particularly when they're cheap. I bought a USB voltage and current tester from Amazon and it arrived today. I've curious about the current draw of a few USB devices I have and it was impractical to use a standard DMM. Below is a quick check of the volts and current draw of a Tascam US-144mkII. In my haste I neglected to connect up a condenser mic to see what it did with phantom power enabled.... tomorrow if I get a chance.
