Samsung 25w Wall Charger Vs 25w Travel Adapter

[stoofa]

Hi All - potentially silly question.
I see Samsung sell both as listed in the title - however the travel adapter is £17 and the Wall charger £29.
If both of these are 25w, why would anyone be buying the wall charger over the travel adapter?

Specs look identical, the travel one doesn't come with a cable, that's about it.
