    Bro, 15a is pretty much standard with 20a outlets being the exception. Still, most appliances are only 1500w in the US.

    Yes obviously you could custom make a 4500w kettle that ran on 115v but nobody sells one.

    Your comment demonstrates a fundamental ignorance… What? Who talks like that. Stupid pedantic fool.







  • I’ve never seen an electric car that used a CVT, normally they are just direct drive. Like the motor spins a reduction gearbox, which is directly connected to the wheels. There is only one gear, not even a reverse, the motor just spins backwards to move the car backwards.

    That is also why smaller electric cars typically top out around 80-120mph, and you need a very powerful one to go 150+ like a Tesla.

    The issue is that at low speed the motor has to spin very slowly which requires immense torque. This is generally overcome with a reduction ratio. The less reduction the faster you can go, but if your motor is not powerful enough then you won’t have enough torque on the steepest hills etc.
