Can I use an extension cord with my Ninja Woodfire Grill?

Yes, you can use an extension cord, but it must be a properly grounded 3-prong GFI outlet and an outdoor extension cord up to 50 feet in length. The cord must be marked with letters 'SJOW,' 16 AWG, and state 'suitable for use with outdoor appliances,' as using the incorrect cord could cause overheating, melting, and voltage drops that affect cooking performance.
