The Chef CHI643BA is a discontinued 60 cm, four-zone induction cooktop with touch controls and a 7.4 kW connected load. Its published specifications make it important to check your bench cut-out, hardwired electrical connection and pan sizes before considering one. The available public evidence does not establish a hands-on performance verdict, and current price and stock are unverified.
What the Chef CHI643BA offers
Chef describes the CHI643BA as a black ceramic-glass induction cooktop with four boosted zones, nine heat settings, touch controls, automatic pan sensing and a residual heat indicator. The product listing also names a child lock and safety cut-off. These are manufacturer-listed features, not a substitute for independent performance testing.

For a household considering a used unit or checking an existing appliance, the key practical question is not just the feature list: the cooktop must fit the bench and electrical installation, and the cookware must suit induction and the zones.

Chef lists the appliance at 590 mm wide, 520 mm deep and 46 mm high, with a required cut-out of 560 × 490 mm. The connected load is 7.4 kW and the connection is hardwired. Confirm the specific installation site and requirements with a qualified installer rather than assuming the unit will fit or connect like another cooktop.

These are manufacturer specifications on the Chef CHI643BA product page. Check the manual and the actual site before installation; a listed cut-out alone does not establish that a particular bench or electrical setup is suitable.
Will your pans work?
The CHI643BA is an induction cooktop, so cookware must be induction-compatible. Its manual also specifies minimum pan diameters by zone; having a pan that works on induction does not by itself establish that its base is large enough for every zone.
| Zone specification in the manual | Minimum cookware diameter |
|---|---|
| Two 1,400 W zones | 125 mm |
| One 1,800 W zone | 145 mm |
| One 2,300 W zone | 180 mm |
Use the minimums in the CHI643BA user and installation manual to check the base diameter of the pans you actually use. The manual also advises using cookware with a clean bottom and cautions that sharp objects and abrasive cleaners can damage the glass ceramic. It warns against steam and high-pressure cleaners.
What independent review evidence says
CHOICE has a model listing for the CHI643BA. Its public page identifies the test timeframe as “2023 or earlier” and gives basic model details, but the expert rating, pros and cons, and detailed results are restricted to members. The public listing therefore does not support a specific test score or a claim that the cooktop is a performance winner or loser. See CHOICE’s Chef CHI643BA listing.
Rank #2
- 【Easy Preset Modes for Everyday Cooking】: Get meals just right with three simple cooking modes: Melt, Keep Warm, and Simmer. These presets help hold steady temperatures without constant checking, so your food doesn’t overheat or burn. Great for melting butter, keeping soup warm, or slowly cooking sauces—just press a button and let the cooktop do the rest. It’s a stress-free way to cook with more control and better results.
- 【Built-In Safety for Worry-Free Use】: This cooktop is designed with safety in mind. It includes Residual Heat Indicators to show if the surface is still hot, Auto Shutdown to turn off the unit if needed, Overheat Protection to prevent damage, and a Child Lock for added control. These features work together to help keep your kitchen safe, especially when you’re multitasking or have kids nearby.
- 【Cook Flexibly with Bridge Zone Design】: Use your space your way. The bridge function lets you connect two cooking zones into one larger zone for big pans or griddles. It’s perfect for making big meals or using specialty cookware. Dual heating coils spread heat evenly, while the cooktop can also shut off zones when pans are moved, helping you save energy and stay safe while cooking.
- 【Booster Mode for Fast Heat-Up】: Need to get dinner on the table fast? Use the Booster function to increase power to one zone and heat up your pot or pan quickly. It’s great for boiling water, searing meats, or cooking on busy nights. This quick-burst power setting cuts wait time without losing cooking control, making your kitchen faster and more efficient.
- 【Smart Pan Detection for Better Results】: The cooktop knows when a pan is there and when it’s not. Smart detection makes sure heat is only used when the right pan is in place. If a pan is removed or not compatible, the cooktop adjusts or shuts off the heat. This keeps energy use low and helps avoid overheating, giving you a safer and more accurate cooking experience every time.
No hands-on testing evidence is available here to establish cooking speed, noise, reliability or real-world results. Chef’s product page has inconsistent review information in its indexed content, so a review count or aggregate rating is not a dependable basis for a verdict.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Is the Chef CHI643BA still available?
Chef marks the CHI643BA as discontinued, and CHOICE also lists its availability as discontinued. That does not establish whether a particular retailer or private seller currently has one: current new stock, used availability and transaction prices are unverified. Check directly with any seller and establish the appliance’s condition, installation history and applicable warranty before buying.
Chef’s support catalogue lists other cooktop models, but the available information does not establish a direct replacement or drop-in fit. For any alternative, compare cut-out dimensions, electrical connection and load, zone layout and pan requirements, controls, safety features, warranty and verified availability.

Warranty and buying considerations
Chef lists a two-year domestic warranty for the CHI643BA. Confirm the terms that apply to the particular purchase and consider any statutory consumer rights relevant to your location; the listing alone does not resolve coverage for a used or discontinued unit.
Quick Recap
- Measure the existing cut-out and compare it with the specified 560 × 490 mm opening.
- Have a qualified installer check the hardwired connection and the 7.4 kW connected load against the site.
- Check induction compatibility and the manual’s zone-specific minimum pan diameters.
- For a used appliance, verify its condition and any warranty coverage with the seller before committing.
