What type of extension cord can I use with the Ninja Woodfire Grill?

You can use an outdoor extension cord up to 50 feet in length, but it must be properly grounded with a 3-prong GFI outlet. The cord should be marked with letters 'SJOW,' 16 AWG, and state 'suitable for use with outdoor appliances.' Using an incorrect cord could lead to overheating, melting, and/or a drop in voltage affecting cooking performance.
