Best Auxiliary Cooktop Buying Guide

Power Source: Electric vs. Gas

The choice between electric and gas largely depends on your existing kitchen setup and personal preference. Electric auxiliary cooktops, including radiant, induction, and coil models, are easier to install, many are plug-in or require simple hardwiring.

Induction cooktops heat pans directly using electromagnetic fields, offering rapid temperature control and energy efficiency, but they require cookware with a magnetic base.

Gas auxiliary cooktops, on the other hand, provide instant visual feedback and precise flame control, ideal for wok cooking or low simmering. Consider your primary cooking style and available power supply when deciding.

If you need a unit that can be placed on a countertop without permanent installation, a plug-in electric model or a portable gas stove is the most practical. For built-in setups, ensure the cutout dimensions match your countertop.

Our cooktop guide covers more details on choosing between power types.

Number of Burners

Auxiliary cooktops typically come with two to five burners. Two-burner models are the most common, offering enough space for a small pot and a skillet simultaneously. They are ideal for small households, dorm rooms, or as a secondary unit.

Four-burner models, like the DYRABREST 3000W unit, provide more cooking real estate and can serve as a primary cooktop in a small kitchen or rental property.

However, they require more counter space and may need a dedicated circuit for electric versions.

Think about how many dishes you typically prepare at once. If you often cook elaborate meals, a four-burner model may be worth the investment. For occasional use, a compact two-burner is sufficient and easier to store.

Size and Portability

If you plan to move the cooktop between locations, counter to counter, indoors to outdoors, portability is key. Look for lightweight models under 15 pounds with built-in handles or a slim profile that fits in a cabinet.

Induction cooktops are generally lighter than radiant or gas units because they lack heavy heating elements. For built-in installation, measure your cutout carefully; standard widths are 12, 24, and 30 inches.

The Karinear 12-inch models are excellent for tight spaces, while the 30-inch gas models from ThermoMate and Yeakcco offer a full-size cooking surface.

Also consider whether the cooktop is designed for countertop use or drop-in installation. Some models are dual-purpose, with removable trim kits for either setup.

If you need a truly portable solution, the Amzgachfktch 1800W induction burner is a single-burner unit that weighs under 5 pounds and can be packed for camping or travel.

Control Type and Safety Features

Control interfaces vary from simple knobs to touch panels with digital displays. Knob controls are intuitive and reliable, even with wet hands, but they take up space on the front panel.

Touch controls offer a sleek look and easy cleaning, but some users find them less responsive. Look for models with child safety locks, automatic shut-off timers, and residual heat indicators, these features prevent accidents and provide peace of mind.

The DYRABREST four-burner model includes a kid safety lock and a two-hour timer, making it a strong choice for families.

Over-temperature protection is another important safety feature, especially for electric models. It automatically turns off the heating element if it reaches unsafe levels, reducing fire risk.

Gas cooktops should have thermocouple flame failure safety devices that cut off gas if the flame extinguishes. The ThermoMate gas model includes thermocouple protection and is CSA certified for safety compliance.

Build Quality and Materials

The construction material affects durability and ease of cleaning. Ceramic glass tops are smooth, easy to wipe clean, and resist stains, but they can crack if subjected to impact.

Stainless steel gas cooktops are rugged and withstand high heat, but they show fingerprints and require more effort to keep clean. Induction cooktops typically have a glass-ceramic surface that stays cool to the touch except directly under the pan.

The Karinear and Jessier electric models use radiant heating under a glass top, offering a balance of performance and easy maintenance.

For gas models, look for heavy-duty cast iron grates and sealed burners that prevent spills from clogging internal parts. Italy Sabaf burners, found on the ThermoMate model, are known for their reliability and even flame distribution.

Check user reviews for long-term durability reports. Our radiant cooktop guide offers more insights on glass top care and longevity.

Installation Requirements

Electric auxiliary cooktops may require a dedicated circuit depending on wattage. Models under 1800W typically plug into a standard 120V outlet, while higher-wattage units (220, 240V) need a special outlet or hardwiring.

Always check the electrical requirements before purchasing, many 220V models, like the Karinear 12-inch, come without a plug and must be hardwired by a professional.

Gas models require a natural gas or propane connection and must be installed according to local codes. If you’re unsure, consult a licensed electrician or plumber.

Built-in cooktops need precise cutout dimensions, measure twice before ordering. Some countertop models can also be built in by removing the trim; check the product manual. For a complete overview of installation considerations, refer to our electric cooktop guide.

Frequently Asked Questions

Can I use an auxiliary cooktop on a standard countertop?

Yes, many auxiliary cooktops are designed for countertop use. Ensure the surface is heat-resistant and flat. Induction and radiant models stay relatively cool around the edges, while gas cooktops generate significant heat, leave ample clearance and never use near flammable materials.

What cookware do I need for an induction auxiliary cooktop?

Induction cooktops require ferromagnetic cookware, stainless steel, cast iron, or enameled iron. To evaluation, see if a magnet sticks to the bottom of your pan. If not, you’ll need to buy compatible cookware.

Most induction models include a pan detection feature that won’t heat if the wrong pan is used.

How do I clean a glass-ceramic auxiliary cooktop?

Allow the surface to cool completely. Wipe with a soft cloth or sponge and a mild cleaner designed for glass cooktops. Avoid abrasive pads or harsh chemicals. For burnt-on residue, use a ceramic cooktop scraper. Our glass ceramic cooktop cleaner guide has specific recommendations.

Can I install a gas auxiliary cooktop in a small kitchen?

Yes, but ensure proper ventilation, a range hood or exhaust fan is recommended to remove combustion gases and odors. Gas cooktops require a gas line connection, so professional installation is advised. Check local building codes for clearance requirements above the cooking surface.

Are portable induction cooktops energy efficient?

Yes, induction cooktops are about 84% energy efficient, compared to 71% for radiant electric and 40% for gas. They heat only the pan, not the surrounding air, making them faster and more efficient. The induction cooktop guide covers efficiency comparisons in detail.

What voltage does an electric auxiliary cooktop need?

Most countertop models run on standard 110, 120V outlets, drawing up to 1800W. Larger built-in units often require 220, 240V connections with higher wattage.

Always verify the voltage requirements of the model you choose, some 220V units, like the Karinear, come with no plug and must be hardwired by an electrician.
