Duxtop 9720LCBI Double Induction Cooktop review

A black-glass Duxtop double induction cooktop with independently controlled zones, an LCD readout and an 1,800 W product rating. The manufacturer describes both countertop and built-in placement, but the exact installation and per-zone power details need confirmation before you plan around them.

Who should look at this model?

The 9720LCBI is for a cook who wants two induction positions instead of one and would make use of a readable display with separate touch controls. Its product page calls the zones independently controlled and lists a maximum rating of 1,800 W. That supports the basic case for cooking two pans in parallel; it does not establish that each side has a separate 1,800 W supply, or that both zones can run at any chosen level together. Treat 1,800 W as the cooktop's listed appliance rating, not a promise of two simultaneous full-power burners.

For a household routine such as simmering a pot while warming a second pan, two independently controlled positions can be more convenient than moving one pan back and forth. The maker does not quantify heating speed or publish a comparative test, so there is no sound basis to promise a faster boil or a particular saute result. The meaningful difference here is two induction zones and their own controls, not a laboratory-proven performance advantage.

Controls: more settings, limited detail

Duxtop lists 20 temperature settings and “20/10” power levels for the burners. That advertised step count suggests more adjustment choices than a very simple low/medium/high interface, and the product image shows an LCD readout for each side. But the page does not spell out which zone gets which power increments, the temperature range, how the setting is sensed, or whether the zones share output. Those are important distinctions: a selectable temperature is not a food-probe reading, and a long list of settings is not evidence of stable low simmering or independent high-power cooking.

The image also shows buttons labeled Boil, Keep Warm, Lock and Timer. Button labels alone do not establish the precise preset temperature, timer length, auto-shutoff behavior or lock sequence for the exact 9720LCBI listing. If a specific timer duration or a one-touch Keep Warm routine is essential, use only an exact manual supplied or identified by Duxtop for that suffix. This assessment leaves those performance details open rather than borrowing them from a different cooktop.

Countertop use is the practical plan to assess

Duxtop's page says the appliance may be used on a countertop or built in, and also mentions kitchens, dorm rooms, RVs and camping. The model-specific instruction trail is not fully aligned: the available Secura-authored double-zone manual copy prints 9720LSBI, while the live product page identifies the listing as 9720LCBI. The maker also associates the page with LCD model terminology, but that alone does not resolve the final-letter discrepancy. Do not transfer the other manual's cutout size, clearances or electrical setup to this listing. Until Duxtop confirms a 9720LCBI manual and installation plan, assess it as a portable countertop product; a built-in opening is not an established fit.

Likewise, a 1,800 W appliance rating matters in an RV or campsite, where available power can be limited. The page's travel-oriented examples do not tell you whether a particular outlet, inverter or campsite circuit is suitable. Confirm the actual supply and operating instructions before using it in a mobile setup. No voltage, cord length, outside dimensions or exact countertop clearances are stated on the product page, so measure and verify those from the correct manual instead of sizing a cabinet or choosing an extension lead from a marketing photo.

Cookware and cleaning

The manufacturer requires magnetic-bottom cookware with a base at least five inches in diameter. Check the bottom of the pan, not the top rim: stainless steel is not automatically induction compatible, while a magnet that holds firmly is a useful first screening test. A base smaller than five inches is outside the stated minimum. The page does not give a maximum pan diameter, so the printed rings in the image are not a substitute for a maximum-size specification.

The smooth all-glass surface is described as wipe-clean with a damp towel. That is a useful everyday design, but it does not make the glass immune to scratches, impact or heat. The page does not give a complete box inventory; cookware shown in the product image should not be assumed to be included. Check what the seller actually supplies, particularly if you need induction-ready pans.

How it compares with other double cooktops

The Duxtop 8620BI/BT-K35 is the stronger choice if an exact, documented built-in installation plan matters: its matched manual identifies the model and gives the cutout and clearance instructions, while also explaining an 1,800 W shared ceiling. The 9620LS/BT-350DZ has a model-paired manual and is a countertop-only two-zone option with a documented 10-hour timer. The 9720LCBI's attraction is its LCD two-zone layout and advertised setting count, but the available evidence does not let it inherit either model's installation or timer details.

Choose the 9720LCBI when two magnetic-base pans, separate zone controls and its listed setting options fit your ordinary countertop cooking. Look elsewhere if you need confirmed built-in dimensions, a minimum simmer wattage, a verified food probe, a known long countdown timer, a measured body footprint or two documented peak-output zones. Its 5-inch cookware minimum and two-zone count are specific; most other operating limits remain unverified for the exact page model.

This assessment is based on Duxtop/Secura's exact 9720LCBI product page and its page-linked image. A Secura-authored manual copy was visually checked but prints 9720LSBI, so its other specifications are not assigned to 9720LCBI. This is not a personal-use or lab test, and current seller stock and package contents were not checked.
