Wattage indicates heating element strength and fan motor speed. In this showdown, the Cuisinart GR-4NP1 5-in-1 Griddler is rated at 1500W while the Ninja Foodi Smart XL 6-in-1 Indoor Grill FG551 operates at 1760W.
The Ninja Foodi Smart XL 6-in-1 Indoor Grill FG551 leads in thermal output with 1760W against 1500W for the Cuisinart GR-4NP1 5-in-1 Griddler. This extra wattage drives rapid convection heat flow for aggressive surface crisping and faster roasting.
