Capacities vary widely. You can find very small pots around 1 ounce, mid-size options listed at 3.16 oz, 5 oz, and 8.8 fl oz (US), common sizes like 16 oz and 20 oz, and larger machines shown with about 680 grams (1.5 lb) capacity.
Common materials include stainless steel and food-grade plastics; some units also use aluminum pots and PET construction for hotplate surfaces.
Power ranges widely — from low-watt appliances around 25 W up to higher-power units at 800 W or 1,200 W. Some commercial models also offer adjustable temperature ranges (for example, about 86–176 °F).
Common accessories include molds, fondue forks or skewers, spatulas, draining/cooling racks, and specialized dipping tools. Larger kits may include multiple small molds and sets of plastic forks or skewers.
Commercial tempering machines emphasize rapid, even heating using high-power operation and internal heating elements or water-bath systems to improve fluidity and mixture consistency.
