I tried using a 12v blender but it does NOT get the job done (Big chunks of ice) so I installed a 3000w inverter (w/150amp throughable breaker) to power a Refer (now a modified ice chest), microwave oven and a 110v blender (The Bullet) which makes the smoothest blends. I only power up the sys when needed. It's kind of nice to nuke a hot dog/ pizza for lunch on the water/channel
