You absolutely cannot guarantee that you can plug North American devices into those plugs because the voltage is twice as high as North America. If your device or its plug does not say it can handle 220V you need to use a voltage regulator or else you risk blowing up your device.
in Brazil when there was no standardization of plugs and sockets this universal model was extremely common. nowadays it is almost not seen anymore, we use the "n" standard, 127v/220v, 60hz, 10a/20a
I have a ton of electronics from when I lived in Canada, UK and some from when I was in Japan. Some modern electronics like the Apple MacBook chargers can work on different voltages when you use a travel adaptor. Some stuff like my Dyson hair dryer cannot operate this way. You need a step up / step down converter if you have a lot of stuff and stay in a single location
