Should charge at 3kW. The car controls the charging rate; is the battery nearly fully charged? If so it will limit the rate.
I know, and it’s not just home plugs…others are the same.That’s weird! To be honest I’ve never used the 13amp cable as I have a 7kW wall charger. You’ve checked the obvious things and I can’t think of anything else at the moment, sorry.
The official 3 pin cable supplied with my 2020 car, with a box as you mention, is marked 10amp / 2.4kw / 100-240v though my newbie theory is the car only allows max 8amp for this cable, or a 13amp one, unless someone can report getting 2.4kw. In which case original poster's problem would then presumably be the wiring in house if cable and car are working identical to the report. I only get 0.5kw but that is possibly because I only tried it for a few minutes I guess or maybe car/cable can detect wiring in my house supports this but I am just speculatingNever seen this particular accessory. My cable has a stonking great box, which I’ve assumed would be 13 amp (like my previous B-class EV).
do you know what….I’d looked all along the cable….nothing that makes any sense.What does the label on the box say? Mine clearly states a max current of 8A.

Mine draws 7.7A

At the time, grid voltage was about 243V and the on-board charger has a near-unity power factor

And that was showing up as 1.8kW on the dash and in the app.
Assuming you've got the same box, and it too is drawing 7.7A, then your slightly lower power (1.7kW Vs my 1.8kW) is probably just down to local voltage variations.
Annoyingly if inspected the cable and read the markings on that and nothing there stated any capacity clearly, but the box though different to yours states 8a 🤬What does the label on the box say? Mine clearly states a max current of 8A.
