Only North/Central America and Japan uses ~100V systems. The rest of the planet uses ~200V systems where more wattage in your outlets is standard.

Brazil (which is in South America) has many cities using 110V/115V/120V/127V (you can see at https://antigo.aneel.gov.br/tensoes-nominais which voltages are used for a given city). Note that a single city can have both ~110V and ~220V, and sometimes both can be found in the same building, or even in the same room.
