Pump extra smoke into your smoker with this device, which will smoke for five hours or more on a single load of fuel (6 cups of wood chunks or chips). The Smoke Daddy Magnum P.I.G. comes with the high output adjustable air pump option. With this unit, you can make lighting the smoker easier by having a high air flow at start, and adjusting it downwards later to the desired smoke output. You can also adjust smoke output on the smoker itself with the valve that is attached to it.
