> The semiconductors in that thing can't possibly be $100,000 in volume. Copper is roughly $10 per kilogram--or $100,000 and you could use 10 metric tonnes--there is no way those things hold 10,000 kg of copper.
I mean... yes, you're right. A better example would be that electric cars can already convert 3-phase to DC (as well as the other way), and the Tesla Model 3 can convert over 200 kW even though it comes with a motor, battery, and an entire car for far less than $100k.
> As for the power, these things are probably more than 90% efficient, so they don't use any more power than the smaller ones (the load they are charging is a fixed size regardless of how fast you charge it). They may use more current, but that's the whole point! These things charge your car faster.
Closer to 95%, most likely. There also theoretically are very few bad chargers (despite exceptions[1]) since most of the cost is in installation, insurance, and weather/tamperproofing.
