Also Worth Considering
How Inverter Microwaves Work
A standard microwave has only one real power level: full power. When you choose 50%, it cycles the magnetron on at full power and then off, over and over. The food gets blasts of energy with rests in between, so edges overcook while the center lags.
An inverter microwave uses an inverter circuit to deliver a continuous stream of reduced power. At 50%, it really runs at about half power the whole time. That gentler, steady energy heats food more evenly.
Inverter models are also lighter and more compact for their capacity, because the inverter board replaces the heavy transformer used in many standard microwaves. That's why many inverter microwaves offer more interior space for the same outside size.
Inverter vs Standard Microwave
| Task | Standard microwave | Inverter microwave |
|---|---|---|
| Reheating leftovers | Hot edges, cold center | More even, edge to center |
| Defrosting meat | Edges start to cook | Thaws more evenly |
| Softening butter, melting chocolate | Easy to overdo | Gentle, more control |
| Poaching eggs, fish | Can turn rubbery | More tender results |
| Boiling water, coffee | Fast | Fast (no real difference) |
| Popcorn | Fine | Fine |
| Weight for capacity | Heavier | Lighter, more interior space |
| Price | Lowest | Slightly higher |
At full power, both types work the same. The difference shows up at medium and low power, which is exactly when you're reheating, defrosting or cooking delicate foods.
Is an Inverter Microwave Worth It?
Worth it if you
- Reheat leftovers often
- Defrost meat in the microwave
- Melt chocolate, soften butter or cook delicate foods
- Want more interior space for the footprint
Skip it if you
- Mostly boil water and make popcorn
- Use the microwave only on full power
- Need the absolute lowest price
Since inverter models now cost only slightly more than standard ones, they're worth it for most households. If you also want browning and crisping, see toaster oven vs microwave and speed oven vs microwave.
How to Choose an Inverter Microwave
1. Pick the right size
| Size | Capacity | Best for |
|---|---|---|
| Compact | 0.7–1.0 cu. ft. | Dorms, offices, one person |
| Mid-size | 1.1–1.6 cu. ft. | Most households |
| Family size | 1.7–2.2 cu. ft. | Large dishes, big families |
Measure your space and leave a few inches around the sides and top for ventilation. Our standard oven size guide covers microwave dimensions too.
2. Aim for 1000 watts or more
Higher wattage heats faster and more evenly. Most mid-size inverter models are 1100–1250 watts.
3. Get a sensor
Sensor cook and reheat measure steam from the food and adjust time and power automatically. Paired with an inverter, it's the biggest step up from a basic microwave.
4. Check the turntable or floor
Make sure your largest dinner plate or casserole dish fits. Flatbed models fit rectangular dishes better and are easier to clean.
5. Consider a trim kit
Some Panasonic models can be built into a cabinet with a matching trim kit, giving a built-in look for less than a true built-in microwave.
Tips for Using Inverter Power
- Use lower power for reheatingReheat plates of food at 50–70% power for longer. The inverter keeps the heat steady, so the center catches up without drying the edges.
- Try sensor reheatCover food loosely with a vented lid so the sensor can read the steam.
- Defrost with inverter defrostEnter the weight, and turn or separate pieces when it beeps.
- Soften butter at 10–20%Low, steady power softens without melting into a puddle.
- Melt chocolate at 30–50%Stir every 30 seconds for smooth results.
- Let food standA minute of standing time lets heat even out before eating.
Care and Lifespan
- Wipe spills promptly so they don't bake on. Steam a bowl of water with lemon for a few minutes to loosen grime.
- Don't run it empty, which can damage the magnetron.
- Keep vents clear on countertop models and leave space around the cabinet.
- Expect around 9 years of typical use. See how long ovens and microwaves last for repair-or-replace advice.
- Register your warranty; inverter boards are the costliest part to repair.
Inverter Microwave FAQs
What is an inverter microwave?
It's a microwave that uses an inverter circuit to deliver steady, reduced power at lower settings, instead of switching full power on and off. That gives more even heating and gentler defrosting.
Are inverter microwaves better?
For reheating, defrosting and delicate foods, yes. At full power they perform about the same as standard microwaves.
Do inverter microwaves cook faster?
Not dramatically at full power. They can save time overall because food heats more evenly and needs fewer stops to stir or rotate.
Do inverter microwaves use less electricity?
They can be slightly more efficient, but the difference on your bill is small. The main benefit is cooking quality.
Who makes the best inverter microwave?
Panasonic pioneered inverter microwaves and remains the best-known brand. Toshiba, LG, Sharp and Emerson also make well-rated inverter models.
How can I tell if my microwave has an inverter?
Check the model name, manual or spec sheet for "inverter." On low power, a standard microwave's sound and light often change as the magnetron cycles; an inverter runs steadily.
Are inverter microwaves less reliable?
Not necessarily. Reliability varies by model, and owner reviews on all microwaves include some early failures. Inverter boards can cost more to repair, so a warranty is worthwhile.
Can you use metal in an inverter microwave?
No. Like standard microwaves, inverter models aren't safe for metal pans or foil unless the manual specifically allows it, such as in some combination modes.
Is a flatbed microwave better than a turntable?
Flatbed microwaves fit large and rectangular dishes and are easier to clean. Turntable models are more common and often cheaper. Both can heat evenly when paired with an inverter.
Can an inverter microwave be built in?
Some can. Several Panasonic models accept a trim kit sold separately for a built-in look. Check the listing for compatible trim kits.
Final Verdict
The Panasonic NN-SN686S is the best inverter microwave for most kitchens: even heating, smart sensor cooking and a proven track record. For big families, choose the Panasonic 2.2 cu. ft. Cyclonic Wave; for easy cleaning and large dishes, the Toshiba Flatbed.
On a budget, the Sharp SMC1464KS and Emerson 1.2 bring inverter cooking for less.
