Mains electricity by country
According to the time at your position that is shown in your profile popup, you are likely to get the 120 V version, while I would get the 230 V version (I got the Standard Series Controller set to 230 V). 100–120 V mains electricity is common only in North and Central America and in Japan, while the rest of the world uses 220–240 V. On the Standard Series Controller however you can switch the voltage internally, while the Elite Series controller additionally switches peripheral devices on and off, which means you need different sockets depending on where you live to match the plugs you find on the routers and the vacuums in your country. See here for a list of all different power plugs and sockets in the world.
So as you can see in the video, on the left 120 V model you have North American 120 V NEMA 5 sockets for the router and the shop vac, while on the 230 V model you have sockets that can take the variety of countries outside North America, like the European plugs like CEE 7/7 or the plugs used in the UK. See below for a map of plugs and sockets used in the world.
