Safe to plug in two PSUs into one outlet?

[philipma1957]

If you have a night-light or lamp, you can kill a breaker and then use it to find every outlet that has no power. Which breakers handle your ceiling fans and lights should be apparent without additional tools.

But even a basic DMM is a very handy tool to have around. Test indoor electric, test batteries, test your car, check miners and PSUs and all sorts of stuff.
