Hi. I joined to ask this one question..but who knows maybe I will stick around and learn other things..lol... I bought an electric 12v anchor winch which is designed to be used with a 12v car battery on a boat. I intend to use it to hoist my bicycles to the ceiling of my garage. However, the AC to DC power inverter that I tried, which outputs 3 amps...makes the winch run very slowly and with a jerking motion. I assume this is because the amperage is way low. So I need a power inverter with a higher amperage rating... My question..how high?
