Best Induction Converter Discs (and When to Skip One)

If you need a converter disc, the Paderno World Cuisine 8-1/4″ Induction Adapter is the one we’d pick for most kitchens. It’s a tri-ply 18/10 stainless steel and aluminum disc with a detachable handle, it’s dishwasher safe, and it’s still on sale in the US in 2026. If you only want to keep using a moka pot, the small Bialetti Induction Plate is the better fit. For big pans, look at an 11-inch disc.

Before you buy one, know what a disc actually does. It turns your induction burner into an ordinary hot plate: the cooktop heats the disc, and the disc heats your pan by contact. You lose most of what makes induction good (speed, efficiency, instant response), the disc gets extremely hot, and several cooktop makers advise against using them at all. A disc makes sense for one or two pans you can’t replace. It’s a poor way to use a whole set of non-induction cookware day to day.

One more thing: many of the discs sold over the last few years have disappeared from Amazon, and a reader pointed that out on the old version of this page. We checked availability for every product below in September 2026. Several well-known discs failed that check, and we explain which ones further down.

Quick comparison

We haven’t put a number in the headline. Only a few discs are both still on sale and documented well enough to recommend with a straight face.

How we researched this

We did not test these discs in a kitchen. We compared what the makers publish (spec sheets, product pages and, where one exists, the instruction manual), checked current availability with US retailers, and read independent measurements of how much energy and time a disc costs. We also looked at what induction cooktop makers say about converter discs and at recurring patterns in owner feedback. For this category the things that matter are diameter, whether the disc has an aluminum core, the handle, and what the manufacturer says about heat settings. Where a maker doesn’t publish a spec, we say so.

1. Paderno World Cuisine Induction Adapter: best overall

This is a restaurant-supply disc from Paderno World Cuisine (its Amazon listing shows the brand as Ilsa). It suits anyone who wants one solid, plain disc for a favorite aluminum, copper, glass or non-magnetic stainless saucepan. It comes in two sizes, so you can match the disc to the pan instead of heating metal the pan never touches.

• Diameter: 8-1/4″ (model A1200121); a 6-1/4″ version (A1200116) is also sold
• Construction: tri-ply 18/10 stainless steel / aluminum / stainless steel
• Handle: detachable stainless steel handle
• Weight: 1.1 lb (8-1/4″); 10.6 oz (6-1/4″), per the Amazon listings
• Care: dishwasher safe, per the product listing
• Price band: $$

What’s good

• The aluminum core spreads heat sideways, so a pan is less likely to scorch in the middle.
• The detachable handle means larger pans can sit flat without a handle in the way.
• The 6-1/4″ size is the right match for a small saucepan or butter warmer on a small burner.
• Paderno also sells it as a heat diffuser for gas or electric stoves and as a plate warmer, so it stays useful if you change cooktops.

What to watch out for

• Paderno doesn’t publish a maximum pan size or a heat-setting limit.
• A stainless handle carries heat. Use a mitt.
• Stock is thin: when we checked, Amazon showed only a few left and one restaurant supplier listed it as unavailable.

2. Max Burton 6010 Induction Interface Disk: best known, with a fixed cool handle

Max Burton (made by Aervoe Industries of Gardnerville, Nevada) makes portable induction burners and sold this disc as an accessory for them. It’s the disc most people have heard of, and its product data sheet is one of the few that says plainly what it can and can’t do. It suits owners of countertop induction burners who want a disc with a handle that stays attached.

• Diameter: 8″
• Construction: two 18/10 stainless steel plates with a layer of aluminum between them
• Handle: fixed, heat-resistant handle (overall length about 15″)
• Weight: about 1 lb, per the Amazon listing
• Dishwasher safe: not published by the manufacturer
• Price band: $$

What’s good

• The maker’s own data sheet admits that efficiency varies with pan type, size and how well heat transfers. That’s more honest than most listings.
• Owners regularly say it’s heavy and well built, and that it’s fine for long simmers.
• It works with any brand of induction cooktop, not only Max Burton’s.

What to watch out for

• The single disc was “currently unavailable” on Amazon when we checked. The 2-pack was still listed, and Walmart still had a listing (we couldn’t confirm Walmart stock).
• The Amazon listing warns that heat transfer drops with larger pans, thicker bases and big volumes, and that the disc can make a noise and turn yellow with normal use.
• A recurring owner complaint: water takes a long time to boil, and there’s a noticeable heat loss between disc and pan.
• The fixed handle can get in the way of wide pans.

3. Bialetti Induction Plate: best for a moka pot

This is the right answer to the most common reason people search for a converter disc: an aluminum moka pot that won’t work on a new induction hob. Bialetti makes it for its own coffee makers, and it has the most detailed instructions of any disc here.

• Diameter: 5.1″ (130 mm), octagonal pattern on top
• Construction: stainless steel (Bialetti doesn’t mention an aluminum core)
• Fits: Bialetti moka pots from 1 to 9 cups, per Bialetti US (the Amazon listing says up to 12 cups), plus small saucepans and butter warmers
• Handle: none
• Care: dishwasher safe, though the manual recommends hand washing
• Warranty: two years, per the manual
• Price band: $

What’s good

• Its small size matches a moka pot base, so little heat is wasted around the edge.
• It’s sold directly by Bialetti in the US as well as on Amazon.
• The manual is clear about safe use (see below).

What to watch out for

• The manual says to use a medium setting and never the highest, and never to switch it on without a pot on it, because it can overheat dangerously.
• It must be centered on the cooking zone, and Bialetti says to use a zone close to the plate’s size.
• No handle, and the manual warns it stays very hot. Let it cool on a heat-safe surface.
• Bialetti says it’s for induction only, not gas or electric stoves.

Also sold at Bialetti US.

4. Grourarty Heat Diffuser Plate: best for large pans

Most of what’s now sold as “induction adapter plates” on Amazon comes from little-known brands with no manufacturer website. Grourarty is one of the better-reviewed. We include it because it comes in five sizes up to 11″, so it can cover a large skillet or stockpot. Treat the specs as the seller’s claims, since there’s no independent spec sheet behind them.

• Diameters: 5″, 6.3″, 7.88″, 9.45″ and 11″
• Construction: stainless steel top and bottom layers with an aluminum middle layer, per the listing
• Handle: yes; details vary by size and aren’t clearly published
• Care: dishwasher safe, per the listing, once cool
• Price band: $

What’s good

• The size range lets you match the disc to the pan base.
• It has a three-layer build with an aluminum core, like the more established brands.
• It was in stock on Amazon when we checked.

What to watch out for

• There’s no manufacturer website, manual or published thickness. What you know is what the listing says.
• An 11″ disc is bigger than the coil in most burners, especially portable ones. The outer ring will run cooler.
• The listing itself tells you to make sure the heating area matches the plate size.

What happened to the discs on the old list?

An earlier version of this page recommended discs from VonShef, Gourmia, Runzi, Concord and Gas One. When we rechecked in September 2026, the Gas One 7.5″ disc showed as “currently unavailable” on Amazon with no restock date. We couldn’t find a maker’s page or a spec sheet for the others that would let us confirm the listings still selling under those names are the same products. Mauviel’s M’Plus magnetic interface disc (8.6″), meant for its copper pans, is still listed on Mauviel USA but was marked unavailable. This category turns over fast. Unbranded 9.45″ and 11″ plates come and go from Amazon, often under different names from one month to the next.

Buying guide: what actually matters

1. Understand what you’re giving up

Induction heats the pan itself through a magnetic field. With a disc in between, only the disc is heated, and the pan warms up by conduction, just as it would on an electric hot plate. Every tiny gap between disc and pan acts as insulation. One independent measurement (Century Life) found a disc setup used about twice the electricity to heat water (0.41 kWh against 0.22 kWh) and took roughly 19 minutes to get near boiling, compared with under 9 minutes for a rolling boil in an induction-ready pan. Expect a slow boil and slow response when you turn the heat down, because the hot disc keeps heating after you lower the setting.

2. The heat risk to your cooktop

An induction cooktop normally stays fairly cool because only the pan gets hot. A disc sits directly on the glass at frying-pan temperatures. The same Century Life test saw a portable burner cut its power from 1500 W to about 1200 W after about 10 minutes and brown the glass under the disc. Many cooktops have overheat protection that will lower the power, cycle it on and off, or shut off with an error code. When Tom’s Guide asked, Miele said it doesn’t recommend converter discs and that they can harm the cooktop’s electronics. BSH (Bosch, Neff, Siemens) said to use the cooktop only as intended. Before you buy, read your cooktop’s manual and warranty terms for anything on accessories or discs.

3. Keep the setting at medium and never run it empty

Bialetti’s manual is the clearest on this. Use a medium setting, never the highest, and don’t switch the plate on without a pot on it. That’s good advice for any disc. An empty disc on high is just a piece of steel getting hotter and hotter on your glass top.

4. Match the diameter to the pan and the burner

Pick a disc about the size of your pan’s flat base, and use it on a cooking zone about that size. A small pan on a big disc wastes heat. A big pan on a small disc only heats in the middle. Most portable burners have a heating coil well under 8″ across, so an 11″ disc on one will have a cool rim. If you’re choosing a burner, our portable induction cooktop guide covers coil sizes.

5. Aluminum core, flat base, handle

A stainless / aluminum / stainless sandwich spreads heat more evenly than plain steel, which is why the better discs use it. The disc and the pan both need flat bottoms. Hammered or warped bases trap air and overheat the disc. A handle matters more than it seems, because you’ll need to lift a disc that’s hotter than a skillet. Detachable handles let wider pans sit flat; fixed handles are easier to grab in a hurry.

6. When a disc is worth it, and when to buy a pan instead

A disc makes sense for one special item: a moka pot, a copper saucepan you love, a glass or ceramic pot, a fondue set, or a guest’s pan for a holiday meal. If you’d be using a disc every day for several pans, you’ll get far better results by replacing the pans you use most with induction-ready ones. See our picks for induction cookware sets and non-stick pans for induction. For coffee, an induction-ready stainless moka pot is also an option.

FAQs

Why can’t I find these discs on Amazon anymore?

A reader asked this in 2023, and it’s still true of many older picks. Most converter discs are made by small brands that come and go, and some brand-name ones (including the single Max Burton 6010 and the Gas One disc) show as unavailable. As of September 2026 the four discs above were listed by US sellers, and the Bialetti plate is also sold directly by Bialetti. If one is out of stock, look for the same features: a size that matches your pan, a stainless and aluminum sandwich, a flat base and a handle.

How do I know if my pan already works on induction?

Hold a fridge magnet to the bottom of the pan. If it sticks firmly, the pan will work. If it barely holds or falls off, it won’t work well or at all. Also look for the induction symbol stamped on the base or printed on the packaging: a coil of loops, often with the word “induction.” Cast iron, enameled cast iron, carbon steel and most modern tri-ply stainless work. Plain aluminum, copper, glass, ceramic and some 18/10 stainless don’t.

Will a converter disc damage my induction cooktop?

It can. The disc gets much hotter than the glass normally does, and independent testing has shown browning of the glass and the burner cutting its own power. Some cooktop makers, including Miele, advise against discs altogether. If you use one, keep the heat at medium, never heat it without a pan on top, and let it cool on a trivet rather than on the glass.

Why does my cooktop beep, show an error or keep cutting out with a disc?

Usually it’s overheat protection. The sensor under the glass picks up the heat from the disc and lowers the power or switches off. Turning the setting down and making sure the disc is centered on the zone usually helps. If it keeps happening, the cooktop is telling you it doesn’t like the disc.

Are converter discs efficient?

No. You’re heating a thick steel disc and then passing that heat through a thin layer of air into the pan. One measurement found about double the energy use and more than double the time to boil. If efficiency is why you chose induction, a disc undoes most of that.

Can I use a converter disc on a gas or electric stove?

Most three-layer discs (Paderno, the Grourarty-type plates) are also sold as heat diffusers or simmer plates for gas and electric stoves. Bialetti says its plate is for induction only.

Can I use cast iron on a converter disc?

You don’t need to. Cast iron is magnetic and works directly on induction. Just lift it rather than sliding it, so you don’t scratch the glass.

Does a disc work with a tea kettle?

Yes, but slowly. If you boil water every day, an induction-ready kettle makes more sense. See our tea kettles for induction.

Bottom line

For one or two pans you can’t replace, the Paderno 8-1/4″ (or 6-1/4″) adapter is the most solidly specified disc still sold. The Bialetti plate is the obvious choice for a moka pot. For anything you’d cook with every day, buying an induction-ready pan is faster, uses less power and is kinder to your cooktop.
