Good idea, on mine I just made a long cord with clips on one end and a lighter socket on the other. I have run mine on the accessory battery on my boat for 2 full days and still had a good charge left. The little inverters are not a battery draining device...sure beats buying expensive D batteries every day, and the aquarium pump creates so many more bubbles !!
