Our Expertise
I’ve been testing kitchen equipment for over five years now. My background in culinary arts and food science gives me a unique edge when evaluating cooking tools.
I spend hours in my test kitchen each week. I cook everything from delicate sauces to high-heat searing. This hands-on approach helps me spot the real winners.
For this guide, I tested each induction cooktop for 30 days. I cooked over 100 meals on each unit. I tracked heat-up times, temperature accuracy, and energy use.
My testing goes beyond basic cooking. I check safety features. I test cleanup ease. I even measure noise levels.
I don’t just read specs. I live with these products. That’s how I give you real insights that matter.

Best for Commercial Use: ChangBERT Portable – Built tough for constant use. Perfect if you need reliability under heavy workloads.
Why Choose an Induction Cooktop?
Let me share why I switched to induction cooking three years ago.
First, the speed amazed me. Water boils in half the time compared to my old gas stove. This saves me precious minutes during busy meal prep.
Second, the energy efficiency is real. My electric bills dropped by about 15%. Induction transfers 83-90% of energy directly to your cookware. Gas stoves waste most heat into the air.
Third, safety became a priority when I had kids. The cooktop surface stays cool. Only the pan heats up. No more burn risks from hot burners.
Fourth, temperature control is game-changing. I can hold a sauce at exactly 180°F. Try doing that on a gas burner.
Finally, cleanup takes seconds. The smooth glass surface wipes clean instantly. No grates to scrub. No burnt-on messes.
What to Look for in a Professional Induction Cooktop
Here’s what I learned matters most:
Power Output: Look for 1800 watts minimum. This gives you the heat needed for serious cooking.
Temperature Range: You need both low and high settings. I use 140°F for keeping food warm and 500°F+ for searing.
Coil Size: Bigger coils heat larger pans more evenly. An 8-inch coil is ideal for most cookware.
Build Quality: Commercial-grade units last longer. Look for NSF certification if you plan heavy use.
Controls: I prefer touch controls for precision. But buttons work great if you wear gloves while cooking.
Safety Features: Auto shut-off and pan detection are must-haves. They prevent accidents and save energy.

Cookware Compatibility: What You Need to Know
All three cooktops require magnetic cookware. Here’s what I learned through testing.
Testing for Magnetic Cookware
Hold a magnet to the bottom of your pan. If it sticks firmly, the pan will work.
Cast iron works perfectly. Stainless steel with magnetic bottoms works great. Aluminum and copper don’t work unless they have a magnetic base layer.
Minimum Pan Size
All three units require pans with at least a 5-inch diameter bottom.
Smaller pans won’t trigger the auto-pan detection. The cooktop will beep and shut off.
I tested with various pan sizes. A 6-inch pan is the practical minimum for good performance.
Flat Bottom Requirement
Warped or rounded pans don’t work well. The bottom must make good contact with the glass surface.
I tested an old warped pan. It heated unevenly and made buzzing noises.
Flat-bottom pans heat evenly and operate silently.
Best Cookware Choices
Based on my testing, here’s what works best:
Cast Iron: Works perfectly. Heats evenly. Retains heat well. Can be heavy to handle.
Magnetic Stainless Steel: My favorite. Lightweight. Heats quickly. Easy to clean.
Enameled Cast Iron: Works great. The enamel protects the glass surface. Slightly slower to heat than bare cast iron.
Carbon Steel: Excellent for high-heat cooking. Lightweight. Heats very quickly.
Safety Features Comparison
Safety matters when dealing with 1800 watts of power. Here’s how each unit protects you.
Auto Shut-Off
All three units shut off automatically when no pan is detected. This prevents wasted energy and potential hazards.
I tested this by removing the pan mid-cooking. Each unit beeped and powered down within 60 seconds.
Overheat Protection
All three have built-in temperature sensors. If the unit gets too hot internally, it shuts down automatically.
I tested this by blocking the cooling vents. Each unit shut off before reaching unsafe temperatures.
Hot Surface Indicator
All three display a warning when the glass surface is still hot after cooking.
This is smart because the glass can stay warm for several minutes after you turn off the unit.
Small Article Detection
This feature prevents the cooktop from turning on if you place a spoon or small item on it.
I tested with various utensils. None of the cooktops powered on accidentally.
Child Safety Lock
The Duxtop and Nuwave have excellent lock features. The ChangBERT’s button design provides inherent safety.
I tested the locks extensively. A determined toddler couldn’t change the settings.
Energy Efficiency: Real-World Testing
I measured actual energy usage over 30 days.
Testing Method
I used a Kill-A-Watt energy monitor to track consumption. I cooked similar meals on each unit.
Results
Duxtop: Used an average of 1.2 kWh per hour of cooking at medium-high heat.
ChangBERT: Used an average of 1.15 kWh per hour at similar settings.
Nuwave: Used an average of 1.1 kWh per hour. The highest efficiency of the three.
Cost Comparison
At my local electricity rate of $0.12 per kWh:
- Duxtop costs about $0.14 per hour of cooking

ChangBERT: 42 decibels – slightly quieter, barely noticeable
Nuwave: 46 decibels – similar to the Duxtop
All three are quiet enough for normal conversation while cooking.
Cookware Noise
Some pans make high-pitched sounds. This happens with multi-layer construction.
I tested various pans. Single-layer magnetic pans were silent on all three units.
Multi-layer stainless steel pans produced a faint hum on all three units. This is normal and not a defect.
Cast iron was completely silent on all three units.
Portability and Storage
All three units are portable, but there are differences.
Size Comparison
Duxtop: 14″ x 11.4″ x 2.5″ – The most compact
ChangBERT: 15″ x 12.2″ x 2.8″ – Slightly larger
Nuwave: 14.2″ x 11.4″ x 2.4″ – Similar to Duxtop
