**NEW VERSION IS UP!!!**http://www.instructables.com/id/USB_Voltage_and_Current_Tester_version_2/
Since it's sometimes necessary to check your USB ports for voltage or if you are curious on what kind of Current draw your devices might be pulling, it would be great to have something to check these.
Now you can.
Instead of just hacking apart USB cables and checking these readings with a Multimeter or one of the Pen Drive style voltage checkers, this instructable will give you a tool that is painless to use.
