Most of the answers to this question that I’ve searched for here and on google get into a lot of technical stuff, intended more for people who are building electronics. I want to understand – from a consumer perspective, someone looking to purchase whichever model is best for them – the pro’s & cons, and if there’s any particular reason to choose 100v over 220v when given the option, for something like a house fan.
In that context – a house fan for example – would the 110v model be less strong/effective than the 220v model?
Is there anything important to note if buying from a bargain site vs. a well known tech company?
Thanks!

Power = voltage * current. Since the voltage is “standard” per country, more power means more current, and current typically heats up the wires and/or may trip the circuit breakers.
Typical household circuits for 110 volts trip at 15 or 20 amps, so you’re looking at 2000 watts of power. A fan or quite a few aren’t gonna be an issue. A TV, most electronics are 100 watts, light bulbs are 30-100 watts, etc. The big consumers are: AC units, area heaters, electric stoves, refrigerators, and electric water heaters. These may need 220 volts just so the current doesn’t trip the breakers.
The big advantage of 110 volts over 220 volts is, 110 volts is very painful but likely won’t kill you, 220 volts can kill you.
In any case, I’m not sure if you’re going to have a choice: most countries have a “standard” for their power grid, and that’s that.
