Very true, Thomas, I didn't mention that because I don't use wall warts but rather regulated (computer) power supply(s). Have even replaced those that come with some otherwise well regarded products. This, possibly due to one problem a while ago. In that, using the supplied, correct wall wart caught fire inside a console that I built. It was not overloaded and worked properly for a while. The connection to (a well known commercial) product was not shorted, the wall wart was a poor product from a country that makes 1,000's of these and some other poor products as well by the 1,000's. The main product that this bad wall wart was powering was and is not defective and is still in service. So even tho a product itself is good, doesn't mean that the wall wart is.
I should mention that (phantom) powering MIDI units by using cheapie MIDI cables is unwise because many of these cheapie cables use small gauge conductors. I've never had a problem using higher quality MIDI cables and I don't daisy chain them either.
Rgds,
