    Why is the iCharger 306B 1000W and not 756W ???

    Hi

    I'm looking into a new charger. And have the Junsi iCharger 306B as one on my list.

    I came to think, though, why is it rated at 1000W...?

    It has a limit of charging 6S
    It has a limit of 30 amps.

    6S at 4,2v per cell, is (6*4,2) = 25,2v

    The required watts for the 30a max is (25,2v *30a) = 756 watt

    I cannot see where the remaining ~250w should be used. But I would like to know. (Some watt-buffer is of course a good idea)

    - Does anyone know the explanation for the excess wattage?

    The 1000w rating is probably input power. Your calculations are based on output power. The device is not 100% efficient and the remaining power is heat loss which is common.
