I have charged in all kinds of weather, including heavy downpours, and never had any problem.
The plugs (and box) are category IP65, which means fully waterproofed.
Elm70' s box must have been defective, which happens from time to time, especially if it is left suspended by the cable.
You'll find more "warnings" in Mitsubishi's documentation that have clearly been inspired by the legal department's fear of litigation.
The Box that was part of the car .. which later the car dealer did replace for free ... was damaged inside .. it got rusted inside
Sign that water proof of the original box was not perfect
Maybe this box has been left under ice and snow ... I don't know
What I know is that I would not trust to leave totally exposed to the elements 24x7 in all weather conditions. This dummy box cost is also quite expensive ... over 300 euro if I recall right.
In my case my PHEV is exposed to elements in my garden ... but the 220v plug and the box are under a "roof" even if this is outside the house, but no rain or snow can reach the box or the 220v plug
220v plug by definition are not water proof .. especially the UK 220v plug ... but if the socket has been placed in a proper place it may have some level of rain protection.
Assuming there is no "shelter" ,,, personally I would buy something like a little dog house for keep inside the charging box in case I need to leave it outside all the time.
In my experience leaving outside exposed to elements, with rain, snow and ice (temperature here can be up to -23deg in winter) ... nothing electronic without special protection can last more then one or two winters
