Yeah, it only matters with things like electric shavers (although those are all battery operated now… so it actually doesn’t matter!), vacuum cleaners, etc. I know if you plug a 120v appliance into 230v it might kill it, but I guess if you plug a 230v appliance into 120v it just won’t turn on or will run slower.
I assume so.
If you’ve got a phone or laptop charger, then input voltage doesn’t often matter. They’ll work with either 120v or 230v.
And in general, you likely won’t be bringing non-charger electrical stuff with you when travelling.
So if you’re installing this in the US, it makes sense to just wire this with 120v. Peoples’ phone chargers will continue to work just fine.
