I have used two extension leads for months now. Even then coming from a short multiple plug little extension lead.TWO Extension leads, "oh the horror", careful you`ll get excommunicated ?
Then goes out the window which can be locked but open and centimetre or so the lead goes out.
Then across a lawn with a bucket over it and another extension lead going another 10m across a public but of grass to the car.
I put a rubber Matt over the public footpath my lead goes across
