Choose an inverter microwave for microwave cooking and reheating, or a convection microwave for baking and roasting. Some countertop combos offer both, so compare the cooking modes and counter space before choosing.

An inverter system controls microwave power. Convection adds oven-style cooking with heated air, so the terms describe different functions.

The Panasonic NN-SN65KB Inverter Microwave focuses on microwave cooking, sensor reheating and defrosting. The Panasonic HomeChef 4-in-1 Combo and Sharp SMC0985KS 3-in-1 Convection Air Fry Microwave add convection and air frying.

Inverter vs convection microwave: what is the difference?

An inverter manages microwave power, while convection adds oven-style cooking. One describes microwave technology, and the other is a cooking mode.

Panasonic says its inverter system provides a continuous stream of cooking power. The NN-SN65KB pairs that technology with Genius Sensor cooking, which adjusts power and cooking time for sensor programs.

Convection adds baking and roasting options. The Sharp SMC0985KS 3-in-1 Convection Air Fry Microwave combines convection with microwave and air fry modes, while the Panasonic HomeChef 4-in-1 Combo adds convection to its microwave, broiler and air fry functions.

Can one microwave have both?

Yes. The Panasonic HomeChef 4-in-1 Combo combines inverter technology with convection cooking, so one feature does not rule out the other.

Think of inverter as a way to deliver microwave energy and convection as another cooking method. A model with both can use microwave power to reheat or defrost, and convection for oven-style cooking.

If you mainly reheat leftovers and cook microwave meals, the extra oven modes may not matter. If you want one appliance for baking and crisping too, a combo may suit your routine.

Which cooks and reheats food more evenly?

For microwave cooking, consider an inverter system and sensor features if even reheating matters to you. Convection adds cooking options, but it does not replace microwave heating control.

Panasonic says the NN-SN65KB's inverter technology helps heat food evenly from edge to center. Its Genius Sensor has 10 sensor cook settings, and sensor reheat adjusts cooking time and power for leftovers.

The HomeChef also has inverter and Genius technologies. Its microwave mode sits alongside broil, air fry and convection, giving you more cooking modes than a microwave-focused model.

Food shape, amount, container and starting temperature can affect heating. Follow the appliance's cooking guidance, including any directions to stir or rotate food.

Is an inverter microwave better for defrosting?

An inverter model with a defrost feature can suit you if you thaw food often. The NN-SN65KB includes Inverter Turbo Defrost, and the HomeChef also has Turbo Defrost.

The Sharp has Auto Defrost and can combine defrosting with cooking and crisping in a multi-stage operation. This can suit meals where you want to move through several stages without resetting the oven.

For occasional thawing, either type may work. Use the appropriate program and follow the food and appliance instructions, since portions vary in shape and thickness.

What can convection add to your cooking?

Convection adds baking and roasting options that a microwave-focused inverter model does not provide. A combo may suit you if you want one countertop appliance for more than heating and defrosting.

The Panasonic HomeChef 4-in-1 Combo includes microwave, broiler, air fry and convection modes. It also connects with the Panasonic Kitchen+ app for recipes and cooking guidance.

The Sharp SMC0985KS 3-in-1 Convection Air Fry Microwave combines microwave, convection and air fry modes. Its multi-stage cooking can use up to 3 functions in one operation, including defrosting, cooking and crisping.

Check which accessories and modes a recipe needs, and whether you have room to store the included trays and baskets.

For more combo options, see our guide to countertop microwave air fryer combos. If you're deciding whether crisping alone is enough, our microwave vs air fryer comparison explains how those appliances differ.

Which model fits your cooking habits?

Choose the NN-SN65KB for microwave-focused cooking, the HomeChef for several oven modes, or the Sharp for a smaller convection and air fry combo. Their capacities and features help distinguish these options.

Panasonic NN-SN65KB Inverter Microwave: best for everyday microwave use

The NN-SN65KB suits routine reheating, cooking and defrosting. It has 1200 watts of cooking power, a 1.2 cu ft interior, a 13.4 in turntable and sensor cooking features.

Its 11 power levels and 15 auto cook options provide choices for common tasks. The keep-warm setting can hold foods such as vegetables, gravy and rolls warm for up to 30 minutes.

Choose this model if convection and air frying are not priorities. For more inverter models and buying advice, read our guide to the best inverter microwaves.

Panasonic HomeChef 4-in-1 Combo: best for several cooking modes

The HomeChef suits cooks who want microwave, broiler, air fry and convection functions in one countertop oven. It holds 1.2 cu ft and has a 14.2 in turntable.

Its 22 in width is an important counter-space consideration. It can be used with an optional trim kit for built-in installation; check the installation instructions before planning a built-in setup.

The Kitchen+ app provides recipes and cooking guidance and can connect with the oven. This model combines several cooking modes with inverter technology.

Sharp SMC0985KS 3-in-1 Convection Air Fry Microwave: best for compact crisping

The Sharp suits a smaller counter where you still want convection and air frying. It measures 19.6 in wide, has a 0.9 cu ft capacity and includes a 10.6 in glass turntable.

Its smaller interior may limit the size of dishes you can use. Measure your usual plates and cookware, then compare them with the available interior space before choosing it.

The multi-stage function can combine up to 3 functions. It can move through defrosting, cooking and crisping in one operation when the food and selected modes suit that sequence.

How much counter space and capacity do you need?

Measure width, depth and height, then match capacity to the dishes you use most. A feature-rich oven may crowd the counter or have less room for your cookware than you need.

The NN-SN65KB measures 20.7 in wide, 15.8 in deep and 12.2 in high. The HomeChef measures 22 in wide, 17.7 in deep and 13.4 in high, while the Sharp measures 19.6 in wide, 15.77 in deep and 11.38 in high.

The HomeChef and NN-SN65KB each hold 1.2 cu ft. The Sharp's 0.9 cu ft interior may suit tighter spaces, but it offers less room for larger dishes.

Allow required ventilation and door-opening space by following the owner's manual. Our microwave size guide can help you match available space and cookware to a practical capacity.

Which should you choose?

Choose an inverter microwave for microwave cooking, convection for baking or roasting, and a combo when you want both. Match the modes you'll use to the counter space you can spare.

Pick the Panasonic NN-SN65KB Inverter Microwave if you mainly need sensor cooking, reheating and defrosting. Choose the Panasonic HomeChef 4-in-1 Combo if its 4 modes and app-linked recipes fit your routine, or the Sharp SMC0985KS 3-in-1 Convection Air Fry Microwave if you want convection and air fry in a smaller unit.

The inverter vs convection microwave choice comes down to your cooking plans: choose microwave power for everyday heating, add convection for oven-style cooking, or select a model that includes both.
