The Frigidaire 30-inch electric cooktop and the Karinear KNC-D23002 are both radiant electric units, but they serve very different kitchens. The Frigidaire is a full-width drop-in with four burners designed for a permanent countertop cutout, while the Karinear is a compact 12-inch, two-burner built-in that suits tight spaces or secondary cooking stations. The Frigidaire draws over 3,000 buyer purchases a month with 1,300 ratings behind it, reflecting strong mainstream demand. The Karinear costs $156.98 and weighs under 10 pounds, making it one of the lightest options in the category. Choosing between them comes down almost entirely to how much cooking space you need and whether you have a standard 30-inch cutout already.
The Frigidaire wins for anyone replacing a standard 30-inch cooktop in a full kitchen; the Karinear wins for small apartments, RVs, or supplemental cooking space where a compact footprint and low price matter most.

The Karinear KNC-D23002 is a 12-inch, two-burner radiant electric cooktop priced at $156.98 with a 4.3-star rating from 836 reviews. It runs on 220 volts and draws 3,000 watts across its two zones, giving it strong output for its size. At 19.3 x 11.4 x 2.1 inches and 9.7 pounds, it is notably slim and easy to position in a tight spot. It installs as a built-in unit, though its compact dimensions make it practical in small kitchens, studio apartments, or as a second cooking surface in a larger kitchen.
Buy this if: Buy the Karinear KNC-D23002 if you need a compact, affordable electric cooktop for a small apartment, RV, office kitchenette, or a secondary prep station. At under $160 and under 10 pounds, it offers real cooking power in a footprint that a 30-inch unit simply cannot fit.
Check price on AmazonNo. The Karinear is 12 inches wide, which is roughly one-third the width of a standard 30-inch cooktop opening. It is designed for compact built-in installations or small countertop cutouts, not as a drop-in replacement for a full-size 30-inch unit. If you have a 30-inch cutout, the Frigidaire is the appropriate fit.
The Frigidaire runs on 240 volts, which is the standard household circuit for full-size electric cooktops in the US. The Karinear KNC-D23002 requires 220 volts AC. Both require a dedicated circuit, so confirm your kitchen wiring before purchasing either unit.
The Karinear KNC-D23002 has the higher total wattage at 3,000 watts across two burners, compared to the Frigidaire at 1,800 watts across four burners. That said, the Frigidaire's four-burner layout spreads capacity across a larger cooking surface, making it more practical for simultaneous multi-pot cooking.
Both hold a 4.3-star rating. The Frigidaire has roughly 1,300 reviews and over 3,000 units sold last month, suggesting it is a widely adopted mainstream model. The Karinear has 836 reviews, which is a solid sample size for a compact specialty unit. Neither rating reveals a clear quality gap; the decision hinges on size and use case.
