Do you have a true 12v at the input to the inverter? I used some pretty thick gauge wire to wire up my cigar lighter into which the inverter plugs but you might be suffering a voltage drop or other resistance that drops the input voltage?

Does anyone know what size inverter I need to charge an older laptop onboard?  We had a 175w then tried 400w. The 409w sort of maintains (plugged in not charging).  Any thoughts?
