Nice tool for the computer tech December 23, 2015 Reviewer: Larry Freese from Cedar Rapids, IA United States   This comes with no instructions but none are really needed. I wish it would have a cap to cover the male end. The timer does not start until you plug a device in the OUT side of the USB meter (female end). Wish I would have picked up one more of these. Good tool for trouble shooting USB ports or devices. Was this review helpful to you?

Great for checking current usage October 10, 2015 Reviewer: Michael Anderson from Herndon, VA United States   USB 2 ports max out at 500ma.  But. many devices these days actually draw more than that.  Not a problem on a USB 3 port that can source 900ma, but it's good to know exactly how much current a device is actually using.
