Light-duty microwaves are small and compact, often designed for one person. Light-duty microwave ovens are smaller in size, typically less than one cubic foot, and usually do not have a turntable. They also usually have lower wattage, around 300 watts, and lower cooking power of around 10 - 15 percent of conventional microwaves. The materials used will vary depending on the manufacturer, but most light-duty microwaves are made from plastic or a combination of plastic and metal. The door is often hinged and opens upwards or to the side. A light-duty microwave oven will often have a smaller capacity than a standard microwave oven, and its interior may be lined with a non-stick coating to make cleaning easier. They are easy to use and usually come with an LCD or LED display. Light duty units are often built with an open-door design to let in more air to prevent overheating. They are usually cordless or require less power than traditional microwaves. Most light-duty microwave ovens have a capacity of 3 liters or less and come with various settings to accommodate various cooking needs.
