An induction cooktop heats compatible cookware directly with an electromagnetic field. Choose a portable burner for flexible counter space, a double unit for two pans, or a built-in cooktop for a permanent kitchen setup.

The right induction cooktop depends on where you'll install it, how many pans you use at once, whether your cookware has a magnetic base, and what electrical connection is available. This guide explains those choices and matches four different cooktops to the situations they suit.

What is an induction cooktop, and how does it heat a pan?

An induction cooktop uses a magnetic field to heat the pan, rather than heating a burner first and transferring that heat to cookware. The pan therefore needs a compatible magnetic base, and its size must suit the cooking zone.

The glass can still become hot through contact with a hot pan. Let the cooktop cool before cleaning, and follow the care guidance for your model.

The main practical difference is how heat reaches the food: the pan is the source of cooking heat. That makes induction different from gas and from electric radiant surfaces.

Read how induction cooktops work for a closer explanation of the magnetic process.

This heating method also affects what you can cook with. If your current pans aren't magnetic, you'll need induction-ready cookware or a different cooking surface.

What types of induction cooktops can you buy?

The three common formats are portable single burner, portable double burner, and built-in cooktop. Choose by how the unit will fit your kitchen and how many pans you need to heat at the same time.

A portable burner can serve as an extra cooking zone, a compact kitchen's main surface, or a temporary option during a kitchen change. It still needs a stable, clear counter area and an outlet that matches the unit's requirements.

A built-in surface suits a longer-term kitchen plan. Its dimensions and electrical requirements affect the cabinet, counter opening and wiring, so those checks should come before selecting a model.

For a moveable one-pan option, the Duxtop 9600LS has one cooking element and a compact countertop format.

If you're comparing portable models, see our guide to portable induction cooktops for countertops. A double cooktop needs enough counter room for its wider footprint, while a built-in model needs a dedicated installation plan.

How do you choose an induction cooktop for your kitchen?

Start with the installation, cookware and number of cooking zones. Then compare power and controls among the cooktops that meet those needs.

Use this order to narrow your options:

1. Decide where it will go. A portable model sits on the counter and can be moved; a built-in model is intended for a fixed installation.
2. Count the pans you use together. A single burner suits one pan at a time. A double unit or four-zone surface can support more simultaneous cooking.
3. Check cookware. A magnet test is a useful first check for a pan's base. Confirm the cooktop's minimum pan size as well.
4. Confirm the electrical setup. Compare voltage, wattage and wiring requirements with the outlet or circuit where you plan to cook.
5. Choose useful controls. Decide whether you want power levels, temperature settings, timers, presets, a lock, or separate zone controls.
6. Measure the space. Check countertop depth and width for portable units. For built-ins, verify the cooktop dimensions and installation requirements before modifying a counter.

This order avoids a common mismatch: choosing a feature-rich model that doesn't fit the available counter or electrical setup. It also prevents buying a portable unit before discovering that your everyday pans aren't compatible.

Which cookware works with induction?

Cookware needs a magnetic base to work on an induction cooktop. Cast iron and many stainless steel pans are compatible, while aluminum, copper and glass cookware usually need an induction-ready base.

Hold a magnet against the bottom of a pan to check whether it attracts. A positive result is a useful screening step, though the pan also needs to sit flat and match the cooktop's minimum size.

A pan that's too small may not be detected. The Duxtop 9600LS specifies a minimum cookware diameter of 5 inches; check the requirements of any other model you consider.

Do not assume that every pan made from a familiar material will work. Stainless steel can vary, and some pans have a magnetic base even when the rest of the body is another material.

Check each pan rather than replacing an entire set by guesswork.

If you want to understand why the base matters, see how induction cooktops work. If you're replacing a gas surface, read what to check before replacing a gas cooktop with induction, including the kitchen's electrical and installation needs.

How much power does an induction cooktop need?

Choose a cooktop whose electrical requirements match the place you plan to use it. Portable models may suit a household outlet, while a built-in cooktop can require hardwiring and a more involved installation.

Wattage describes available electrical power, not a guaranteed time to boil or a result for every recipe. Cookware, pan size and selected setting also affect the heat delivered to food.

The Duxtop 9600LS uses a 110/120 V, 15 amp connection, which the brand describes as standard in North American homes. Its power levels range from 100 to 1,800 W, giving you several choices for different cooking tasks.

The Nuwave Double Pro offers settings of 900, 1,500 and 1,800 W at 120 V. Its Dynamic Watt Technology distributes energy between the two zones, so plan for shared available power rather than assuming both burners can each draw the full setting at once.

For a fixed installation, the Empava Ease is a 30-inch, four-zone, hardwired drop-in model with 7,400 W of power. Confirm the cabinet opening and electrical requirements before planning the installation.

To estimate energy use across different settings and cooking times, use our guide to induction cooktop electricity use. For installation planning, read what to check before installing a built-in induction cooktop.

Do controls and temperature settings matter?

Controls matter when they match the jobs you cook most often. Power settings adjust the cooktop's output, while temperature settings let you select a target for more controlled cooking.

A range of power levels can help with tasks from heating quickly to reducing output for a gentler simmer. Temperature settings may suit cooks who want to work from a chosen target, especially for delicate foods that need steady heat.

The Nuwave Gold Precision offers temperature adjustments from 100°F to 575°F in 5°F increments. That fine adjustment suits someone who wants more choice between temperature targets; skip it if a basic power control is enough for your routine.

The Duxtop 9600LS uses 20 preset power levels and 20 preset temperature levels. It also has a fast boil button, keep warm function, child safety lock and timer, so it suits a buyer who wants multiple controls on a single portable burner.

Controls aren't a substitute for matching the pan to the task. Start with the cooktop's instructions, use cookware that fits the zone, and adjust settings as needed rather than assuming a particular number will behave the same on every pan.

Read which induction cooktop features are worth having to compare features such as timers, locks and temperature control.

What should you know about a double induction cooktop?

A double induction cooktop is useful when you need two pans, but its zones may share available power. Check how it allocates power and whether each burner has separate controls.

The Nuwave Double Pro has two cooking zones with their own controls. Its Dynamic Watt Technology is designed to distribute energy between the burners, which suits a meal with one pan heating quickly and another held at a lower setting.

The unit is 23.6 in wide and 14.2 in deep, so measure your counter before choosing it. It supports up to 25 lb on each cooking surface, which gives you a stated weight limit to consider when choosing cookware.

It's a strong fit for people who cook full meals with two pans but don't want a built-in surface. Skip it if you usually cook with one pan, have limited counter width, or need each burner to draw full power at the same time.

A double unit also takes more room to store than a single burner. If this format fits your routine, compare best double induction cooktops for bigger meals and see how to use a double induction cooktop and share its power.

When does a built-in induction cooktop make sense?

A built-in induction cooktop makes sense when you want a permanent surface and can plan its cutout and electrical connection. It offers multiple zones in a fixed kitchen layout, but it's not a plug-in countertop shortcut.

The Empava Ease has four zones in a 30-inch drop-in design. Its touch controls include a boost function, independent zone timers, child lock, residual heat display and overheating prevention.

Choose it if you're planning a kitchen installation and will use several pans at once. Skip it if you need a portable appliance, can't confirm the opening or wiring, or aren't ready to coordinate the electrical work.

Before buying, check the dimensions against the actual counter and cabinet plan and confirm the wiring requirements with a qualified installer. The 30-inch built-in cooktop guide can help compare this general format with other options.

How should you set up and care for an induction cooktop?

Set up a portable cooktop on a stable, clear counter and use a compatible pan that fits its cooking zone. For a built-in model, follow its installation instructions and confirm the cutout and electrical setup first.

Before the first cooking session, identify the controls you'll use and check the owner's instructions for cookware requirements, safe operation and cleaning. Keep the cooking surface clear of objects that could interfere with pan placement.

Use the pan size specified for your cooktop. Centering a flat, compatible pan helps it make consistent contact with the intended cooking zone, while a pan that's too small may fail to register.

After cooking, allow the glass to cool before cleaning. Use care suited to the glass surface and avoid dragging cookware across it, which can scratch or mark the finish.

For detailed surface-care steps, read how to clean an induction cooktop without scratching it. A clean, cool surface and suitable cookware help keep everyday setup straightforward.

What common induction cooktop mistakes should you avoid?

The most common mistakes are using incompatible cookware, overlooking power limits and buying before measuring. Each can make an otherwise suitable cooktop frustrating to use.

• Assuming every pan works: Check the base with a magnet and verify the minimum pan size. A pan that isn't detected won't heat as intended.
• Ignoring shared power: A double cooktop may distribute power across its zones. Don't plan a high-output task on both sides at once without checking the model's operating guidance.
• Forgetting the installation: A built-in model needs the right opening and electrical connection. Confirm both before selecting a fixture or arranging counter work.
• Choosing controls by quantity: More settings help only if they fit your cooking habits. Pick temperature control or presets when you expect to use them.
• Cleaning while hot: Let the surface cool before wiping it. Contact with a hot pan can leave the glass warm after cooking ends.
• Overlooking storage and counter space: Portable doesn't mean tiny. Measure the unit's footprint and decide where it will sit during use and where it can be stored.

Which induction cooktop should you choose?

Choose the Duxtop 9600LS for a versatile single portable burner, the Nuwave Double Pro for two-pan countertop cooking, the Empava Ease for a permanent four-zone installation, or the Nuwave Gold for fine temperature adjustment on one pan.

The Duxtop 9600LS suits a small kitchen, an extra cooking zone, or someone who wants a portable burner with a broad set of power and temperature choices. Skip it if you need more than one pan cooking at the same time or want a built-in surface.

The Nuwave Double Pro fits cooks who regularly prepare two dishes at once and have enough counter space for a wider unit. Skip it if you mainly cook one pan at a time or require full, independent power on both zones.

The Empava Ease 30-inch suits a planned kitchen remodel or a permanent replacement where four zones and a hardwired setup make sense. Skip it if you need a temporary appliance or haven't confirmed the opening and electrical requirements.

The Nuwave Gold Precision is for one-pan cooking where fine temperature adjustments matter. Skip it if preset power levels are all you need and you have no use for a wider range of temperature settings.

What is the final decision rule for an induction cooktop?

Pick by fit first: portable single for flexible one-pan use, portable double for two pans, and built-in for a planned fixed kitchen. Before choosing any induction cooktop, confirm compatible cookware, available power and the space it needs.

For a portable model, measure the counter, check the outlet and test your pans with a magnet. For a built-in cooktop, confirm the cutout and electrical plan before arranging installation.

If you still need to compare permanent cooktop widths, see induction cooktop sizes. If you want an extra cooking zone that can be moved or stored, compare portable induction cooktops for countertops.

Frequently asked questions

What is an induction cooktop?

An induction cooktop uses an electromagnetic field to heat compatible cookware directly. The pan needs a magnetic base, and the glass surface can become hot from contact with that pan, so check cookware compatibility before use and let the surface cool before cleaning.

Do induction cooktops need special pans?

Induction cooktops need cookware with a magnetic base. Cast iron and many magnetic stainless steel pans work, while aluminum, copper and glass cookware usually will not unless they have an induction-ready base, so test with a magnet and check the cooktop's minimum pan diameter.

Is a portable or built-in induction cooktop better?

A portable induction cooktop suits occasional use, small kitchens or extra cooking space because it sits on a counter and can be stored. A built-in model fits a permanent kitchen plan and needs an appropriate cutout and electrical setup, so choose based on space, installation and cooking zones.

How much power does an induction cooktop use?

Power use depends on the model, setting and cooking time. Portable cooktops can offer several wattage settings, while a built-in model may need hardwiring, so compare its electrical requirements with your available circuit and use our guide to induction cooktop electricity use to estimate consumption.

Can induction cooktops share power between burners?

Some double induction cooktops distribute power between both burners, so the power available to each zone can change as you cook. Check how the model shares wattage and whether each burner has separate controls, especially if you want one pan simmering while another heats quickly.
