Cheap Fridge Idea
This is only a good idea if you have a really really really really long extension cord. You could not run your engine enough to keep the batteries charged to power the inverter, ice would be a better solution. Rather than an inverter why not buy one of the ice box conversion kits? Manufacturers such as Seafrost, Technautic, Glacier Bay and Isotherm make the better units. I’m certain this would be a more efficient solution and would enhance the value of your boat at time of resale.
