What is the difference between commercial and household induction cookers?

Please verify the following points and require itemized written supplier responses:（commercial induction cooker induction-comparison） Commercial induction cookers have higher power and heavier-duty cooling, panels and coils for continuous work; household units may reduce power under heavy use. Check rated power, duty time, panel load capacity, cooling and warranty terms. Define capacity, accuracy, materials and operating environment before requesting quotes on a uniform basis. Request specification sheets, test reports, certificates, maintenance manuals and spare-part lists. During acceptance, verify appearance, dimensions, functions, safety protection and packaging, and keep test records. Do not compare unit price alone; include customization, freight, spare parts, after-sales support and downtime risk. Keep written records of inquiries, confirmations, FAT, acceptance and warranty commitments.
