This little tester is a great Mini Tester for USB diagnostics. Pair it up with a break out USB tester and you can do some very complicated testing of voltage load and stability. Its well worth the money

I am using this device to check various charging cables and chargers on apple devices (MBP, iPhone, iPad). Display values seem accurate so far, however the display only turns on if a device is connected.
