Now that I'm pretty much stuck at home for a while I decided to do some organizing. One of the items on my list is to sort out my ever growing collection of about 50 wall warts. Some are AC, some DC, some 12 volts, some 9, some have special connectors, others are standard 2.5 mm barrels. During the sorting out and testing process, I realized many of my so called 9 Vdc adapters are more like 12 Vdc despite what the nameplate says. The Boss adapters are pretty true to their rating and regulate voltage as well (I measured voltage at no load and 100 ohm load). A lot of the generic 9 Vdc adapters measured out to be 12 Vdc. Some as high as 15 Vdc.
Moral of the story... Don't go by the sticker on the adapter. Measure the the voltage.
