Can I use an extension cord with the 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' to avoid overheating, melting, and voltage drops that could affect cooking performance.
