Can anyone tell me the power draw of a MacBook (operations only, not recharge)?
I'm shopping for an AIS receiver. The SR161 looks best but I will have to run 24-7 on my next passage so power draw is a big deal. NASA makes a unit called the "AIS Radar" (not a real radar) with an inferior receiver, but has it'a own processer and screen. Power draw for the AIS Radar is less than one amp on 12v DC.
I'd rather have the SR161 running through a MacBook, but am concerned that it will drain my batteries too much on the dusk to dawn watch.
