These come in 3 different sizes, this is the smallest one.

I bought the black one but they also have them in white for slightly more.
I’m not sure if it supports 110-240v but coming from UK it would work with 240v mains for sure, people from 110v countries should try to find if it supports 110v mains power before buying.
