Low Wattage Microwaves for 2023– Will Save Energy

I too often use my low-wattage microwave to reheat leftovers in the morning before I leave for work. Black+Decker EM720CB7 is my favorite microwave oven.

To save you time, I took 30+ hours to test the best low wattage microwaves. And here in this article I share my experience with each low power microwave.

What are the features of a good low-wattage microwave?

  • Turntables. A turntable is reasonable for rotating your food to ensure it heats evenly. Microwaves with removable turntables are easy to clean. With a microwave without a turntable, you need to stop the cooking cycle underway and turn the plate or cup around.
  • Preset functions. The functions are vital for defrosting and reheating. However, these appliances tend to be pricier.
  • Good size. Microwaves come in different sizes. Some can fit a 12-inch cabinet depth, 14-inch cabinet depth, and more. If your kitchen’s space is tight, a good option would be a compact countertop microwave.
  • Wattage/energy efficiency. How powerful should your microwave be? If you’re making popcorn, defrosting veggies, or reheating food in small quantities, a 700 up to 900-watt microwave is a good choice. For quick heating, a 1000-watt or more will work better.

Today, microwaves are available in different colors, sizes, wattage, and functions. You can get a low-watt microwave that outclasses high-end ones.
