How much HP does a cordless drill have?

A wide range of electric drills are available with more or less power (one-half horsepower is about average) and with various maximum speeds (most models top out at between twelve hundred and twenty-five hundred revolutions per minute).

Are amps or volts more powerful?

You can’t have a lot of amps without a lot of volts. So, back to which kills you, the amps or volts. Given your body is a constant resistance, it really is a combination of both. Higher voltage means higher amperage, and thus higher voltage has more potential to kill.
