should i choose a 40 amp portable EV charger or and 40 amp EV wall charger?

[lookatme00]

Hey everyone, I'm in the market for a 40-amp EV charger, but I'm stuck on whether to go with a portable one or a wall-mounted one. Does anyone have experience with both? What are the true pros and cons of each? Thanks!
Here are the two models I’m considering.

In UK, they’re all wall mounted… or pole mounted… fixed down, anyway.

Except, I believe the roadside recovery companies have charge points on trailers, powered by diesel generators to rescue electric vehicles that have run out of charge.
