Using a higher voltage, like 42 V instead of 12 V, allows for the same power to be delivered with less current. This is because power (P) is the product of voltage (V) and current (I), as given by the equation P = V * I. Therefore, for a given power, increasing the voltage allows for a decrease in the current required.
