both microwave oven and microwave oven have microwave heating function, which one is hot depends on the power and efficiency of this machine, and it is marked on it. There are other factors that will affect the heating time. Microwave ovens and microwave ovens have power sizes of 7W, 8w and 9w respectively, depending on the mode of microwave heating. There are tray-type and flat-type microwave ovens and microwave ovens. The speed of heating depends not only on the power of microwave and light wave heating pipes, but also on the variety and size of the food you want to heat, which will affect the heating time, as well as your own cooking skills. At present, the light wave oven on the market is a combination oven of light wave and microwave. The microwave function is mainly used to heat food and meals, and the light wave is mainly used for barbecue. Whether it's a microwave oven or a light wave oven, their microwave functions are the same, basically the same. If you use it to heat meals, there are differences, but the time difference will not be particularly great. I suggest you look at the brand and quality first, then the power, the grade energy consumption of electrical appliances, and then the heating method. If the food you need to heat is rarely easy to cook, it won't take long. On the contrary, the heated food is difficult to cook, and the heating time will be a little long.
