OK, file this under "impulse buy"... But it could be handy. I do a lot of IT/electronics diagnostic stuff, and it's handy to know voltage/current draw (or current output capability) of certain devices. Normally I would use a meter and a butchered USB cable. But this handy-dandy little inline voltage/current reader is only the size of a flash drive! Very handy, and it was on clearance at Menards for $9.95. I saw the package and I thought "USB Multimeter, huh, where do the probes connect?". I thought it was an on-screen actual multimeter. It isn't that at all, but it's still neat, and totally worth $9.95 to me.

I tested a few of my chargers with my phone attached as a load:

I was kinda hoping it showed volts and amps at the same time, but it switched back and fourth about every second or two.
