Wattage requirements are determined by two main factors, blade size and the type of food being cut. For standard seven or eight-inch blades, most slicers will come equipped with a 120 – 200 watt motor. At this point, users will have no trouble cutting basic deli meats, vegetables, cheeses, and bread.
For a nine to twelve-inch blade, a 320 – 420 watt motor will be required, allowing users to cut thick slabs of lean meat with little issue.
