Hook it to a receiver and servo and see if you can use the transmitter to move the servo. :)
Seriously, a voltmeter would be the easiest way and you'd also be able to find out what the exact output voltage is. Maybe take it to your LHS - someone there must have a meter...
YOu got a pic of it. I have the receivers with a light on it to. The receiver will tell you if you got power. What happens if you put a receiver pack on it instead.
Peace!
