I live in a 50 year old house. All the breakers are 16A, so 220V x 16A = 3.5kW

The electric sauna does three-phase @ 400V. My energy tracker usually peaks around 9.5kW when it’s heating.

I thought we solved this for good in the 80s?

I guess that particular question didn’t age so well.

I have a thin stick-on slider for my laptops. It’d look clunky, but you can stick it on any tablet or phone.
