This stainless steel thermal cooker features HEAT and KEEP WARM functions. The power plug is a 3-prong type. A conversion adapter is required. It is not included. It appears to be used by placing it on the black round tray below. It clicks into place, but feels a little loose. I don't think it will affect usage. I think it's just the way it is. - Type: Thermal Cooker - Material: Stainless Steel - Function: With warming function - Operation buttons: HEAT, KEEP WARM Thank you for viewing. 260203-02U ↓↓ Click our hashtag to see our stock! #GarageKT_BusinessSupplies
