Thanks for all the responses.
One further question: Regarding the fact that AA only supplies 75 watts of power. Does this impact whether I should buy an inverter rated at 80 watts continuous power or 130 watts continuous power, or would both work fine but still only be able to deliver 75 watts because that is all AA is supplying?
