My WSM Mini will run for 5-6 hours on a very small amount of charcoal. Pop it in the oven for the rest of the time for set and forget. ECBs ( Brinkman Electric) do work. However, mine don't get much use since I built the WSM mini. The WSM mini is perfect for a pork butt. The small size seems to make it really hold a steady temp with no spikes.
