And Power is measured in Watts. The dimension of power is energy divided by time. So in basic terms, someone charging at 5 amps for 30 minutes should about equil someone charging at 40 amps for less than 4 minutes. At least in the ballpark. So a RC race track where everyone charged at 40 amps would use the same power as a race track where everyone charged at 5 amps. Or if 1 person eats a foot long in 5 minutes equals 2 people eating 2 6" in 2.5 minutes. Same Footlong.
No, if everyone is charging at 40 amps they're using more power. They're using the same energy overall compared to a lower amp draw. The mains wiring, fuse boxes etc aren't rated for energy usage, they're rated for current draw.
To break it down further, volts is joules per coulomb. Amps is coulombs per second. Watts is joules per second, or in other words volts times amps. More current at the same voltage is definitely more watts.
