    I have a infant swing that runs of 4 D size batteries - 6V - essentially it has a motor, some lights and some music. I am planning on hooking up a DC adaptor to avoid battery hassles. I measured the amperage as the swing was running and measured a peak amperage of 600mA

    My question is I have a 7V, 1.7Amp adaptor lying around and I was wondering whether the slightly higher voltage (7 vesus 6) and amperage rating (1700mA versus 600mA) would affect the motor or assorted electronics if I used this adaptor

    Thanks for replies

    So long as the voltage is 7 and not any higher then there will be no problem.

    Can you try it and measure the actual voltage when the swing is running?

    The current capacity is the figure it can deliver when necessary, not what it will automatically produce.
