My old electric coil stove had finally died. I cook a lot, mostly with cast iron, and I knew I wanted induction for its speed and control. But I also worried: cast iron is heavy, abrasive, and can warp if heated unevenly. After reading reviews and talking to a friend who used induction in his food truck, I settled on a portable unit to start. I ordered the Duxtop 1800W model. It arrived in two days. I plugged it in, slapped my ten-inch Lodge skillet on top, and within a month I had accidentally left the burners on electric. Induction is different. You have to learn its quirks.
Why cast iron and induction can be tricky
Cast iron is ferrous, so it works with magnetic induction. But the real issues are physical. A skillet that has a slight convex bottom from years of high gas flames will rock on a flat glass cooktop. That means poor contact and uneven heat distribution. Worse, induction transfers energy so fast that a cold cast iron pan can warp if you crank it to max right away. I learned that the hard way with an old cheap cooktop I borrowed: it left a circular scorch mark on the pan’s bottom. The Duxtop has a low-profile design with a sturdy ceramic surface that feels built to handle the weight. I saw no rocking, no hot spots, and the pan stayed flat after repeated use. The key is to preheat on medium and let the pan expand slowly.
Duxtop’s design: a practical solution
The Duxtop unit sits lower than most portable induction burners. That matters because a heavy skillet sits more stable—less chance of tipping when you deglaze. The control panel is simple: plus and minus buttons for power, a timer, and a keep-warm setting. No touch sliders that ignore wet fingers. The ceramic glass has a slight raised rim that prevents pans from sliding off. I tested it by intentionally shoving the skillet sideways; it held. The temperature sensor reads the pan surface directly, so when I set 350 degrees for cornbread, it actually holds near 350, not oscillating wildly like some budget models. No memory presets, but I don’t need them.
A real-world test: searing steak and cornbread
One night I wanted a proper seared ribeye without smoking out the kitchen. Induction allows you to go high—power level 9 on the Duxtop—and the pan responds in seconds. I preheated my cast iron for about two minutes, dropped the steak, and got a crust that would make a grill proud. No flare-ups, no noisy burner. Later I made cornbread in the same pan at 375 degrees. The Duxtop held the temperature steady without cycling off and on the way an electric coil does. The bottom of the cornbread came out an even golden brown, not darker in the center. That uniform heat distribution comes from the coil design inside the unit: it’s a single large induction coil that matches the bottom of most pans up to ten inches.
The small details that make a difference
Cleaning is trivial. Spill happens, but the glass wipes clean with a damp cloth. The only thing I watch for is sugar: if you spill syrup or jam, it can burn onto the glass and leave a stain. That happened once when a pancake flipped sideways. The error code system is helpful but not nagging—if the pan is too small or not ferrous, it simply blinks and shuts off. The fan runs gently, quieter than my old refrigerator compressor. The cord is long enough to reach a wall outlet without a power strip. After six months, I have never scratched the surface. I do still use a silicone trivet to set the pan down after cooking, just out of habit.
„Cooking on induction taught me that the tool you use matters less than the patience you bring to it. The Duxtop didn’t make me a better cook. It just stopped getting in the way.“
