Review: Tested with Voltmeter, Working Perfectly! - A good AC/DC transformer adapter with a variety of six tips/sockets suited my need. I've tested it by using a voltmeter and the VDC output is having an error of less than 1% from the total output voltage. The voltage switcher is really well designed, as it has a step lock so no chance you will adjust the switcher to the middle of two different voltage settings. Recommended.
