5W USB-C charger block - eviltoast

Hello,

I am looking for a 5W USB-C charging block to best charge my iPhone overnight (and minimize heat production). I’m not sure if it’s just me but I don’t see a 5W output charger block on Amazon, unless I am being dumb and I actually need to calculate the output wattage, which is different from the stated “face value” wattage? Not sure which is the case.

Anyhow, if anyone sees/knows a 5W USB-C charger block on Amazon, I’d appreciate if you could tell me the name of it or link it. Thank you!
