Warming trays or buffet warmers are necessary kitchen appliances when it comes to food warming especially at the outdoor events. For hotels and restaurants, food warmers are of great usewhen the foods are ready when guests are late or events get pushed back. These scenarios do happen quite often and it’s always better to have a few units on hand in case of emergency. Today there are numerous styles of food warmers and many of them use candles and chafing fuel; some with power cords while some are designed to be cordless use. For the sake of safey and convenience not having the need to search for power plugs, we always recommened the cordless electric buffet food warmers .
