Long-simmer stock cooks
If you make one pot of vegetable stock at a time, look for low-heat control you can adjust after the stock reaches a boil. A timer can help you manage the cooking session, but it does not replace supervision.
Who is a portable hob for?
Large-batch cooks
If you use a wide stockpot, its flat base needs to fit the hob’s stated cookware range. Buffalo Appliances lists a 120–320 mm compatible pan range for its CP799; the unit’s size and weight also need room in your kitchen.
Small-kitchen extra-zone users
A portable single-zone hob can provide an occasional cooking position and be put away between uses. Check your available worktop and storage space, as well as whether the stockpot you already own works with induction.
What matters when choosing?
Check your stockpot and the hob’s low settings before deciding how much worktop space to give up for a wider cooking surface or a second zone. The concerns below distinguish consumers by the need they would put first.
| Concern | What to check | Who this matters to |
|---|---|---|
| Gentle simmering | Compare the lowest manual setting and timer controls; follow the manual’s cooking and supervision instructions. Tefal UK lists a 300–2100 W manual range for its Everyday Slim IH210840. | If I cook stock for several hours, I want to turn down the heat after boiling rather than rely on a preset that may not suit my pot. Around 37% of consumers would put simmer control first. |
| Stockpot fit | Check that the pot is induction-compatible and compare its flat base with the exact hob’s supported diameter range. Tefal UK states 12–26 cm for the Everyday Slim IH210840; Buffalo Appliances states 120–320 mm for the CP799. | My wide stockpot is useful only if the hob accepts its base, so I would settle compatibility before looking at other controls. For around 27% of consumers, pot fit would be the primary concern. |
| Space and storage | Measure both the clear worktop area and the storage space, then compare the hob’s dimensions and weight. Tefal UK describes the Everyday Slim IH210840 as 45 mm thick; Buffalo Appliances lists the CP799 at 390 × 490 mm and 7.25 kg. | When the hob comes out only for stock-making, I need somewhere practical to use and store it. Space would come first for around 18% of consumers. |
| A second pan | Decide whether two independently usable zones are necessary, and check the appliance’s total rated load and dimensions. Judge specifies 3100 W for its double induction hob. | If I simmer stock while cooking another component, a second zone changes what I can do in the same session. Around 18% of consumers would prioritise that two-pan workflow. |
Buying mistakes to avoid
-
Assuming any stockpot will work with induction
An induction hob needs suitable cookware, and the pot’s flat base must also fall within the particular model’s supported size range.
Use a magnet as an initial check on the base, then confirm both cookware compatibility and base diameter against the hob’s product information.
You may need a different stockpot if your existing one is unsuitable.
-
Treating the hob’s wattage as approval for any extension lead
An overloaded extension lead, adaptor or wall plug can overheat. Electrical Safety First also warns that a cable reel must be fully unwound to achieve its marked rating.
Prefer a suitable wall socket. If an extension is unavoidable, check its marked rating against the total connected load and do not daisy-chain extension devices.
-
Choosing a compact hob without measuring the pot
A small hob’s stated cookware range may exclude a wide stockpot even when that pot is induction-compatible. Tefal UK states an upper pan diameter of 26 cm for the Everyday Slim IH210840, while Buffalo Appliances states 320 mm for the larger CP799.
Measure the stockpot’s flat contact base rather than its rim, then compare it with the exact model’s guidance before deciding how compact the hob can be.
-
Buying two zones for a one-pot task
A second zone lets you use another pan alongside the stock, but it does not by itself improve your stockpot’s fit or remove the need for induction-compatible cookware.
If you normally make stock in one pot, prioritise that pot’s fit and the controls you need for a simmer. Consider two zones when simultaneous cooking is part of your routine.
A double-zone unit also needs more worktop space.
Brands to consider
These product lines illustrate different ways to handle a stockpot; compare the exact model rather than assuming every hob from a brand has the same controls or cookware range.
Tefal
Tefal’s domestic portable induction range includes the Everyday Slim IH210840 for a compact, single-pot setup.
- Tefal UK lists a 300–2100 W manual range, slow-cook and keep-warm functions, a timer and a 45 mm body for the IH210840.
- Its stated 12–26 cm induction-pan range needs checking against your stockpot’s base.
Judge
Judge offers portable single- and double-zone induction options for cooks deciding whether stock preparation needs a second pan.
- Judge specifies ten temperatures from 60°C to 240°C for its 2000 W single hob and settings from 80°C to 220°C for its 3100 W double hob.
- The double-zone format calls for more worktop space; check cookware compatibility and the electrical arrangement for the model you choose.
Buffalo
Buffalo’s CP799 is a larger, commercial-style countertop induction hob to consider when a wide stockpot drives the choice.
- Buffalo Appliances states a compatible pan range of 120–320 mm for the CP799.
- Its stated 390 × 490 mm footprint and 7.25 kg weight make placement and storage important checks.

Check that your stockpot has a suitable magnetic base, confirm the supported pot-base diameter, and check the plug and electrical details for your intended setup. Keep the hob supervised during cooking.
Frequently asked questions
Will my existing stockpot work on a portable induction hob?
It will work only if its base is induction-compatible and falls within the chosen hob’s supported pan range. Measure the flat base, not just the rim: Tefal UK states 12–26 cm for the Everyday Slim IH210840, while Buffalo Appliances states 120–320 mm for the CP799.
Can I leave vegetable stock cooking if the hob has a timer?
No—a timer can help manage cooking, but it does not replace supervision or the appliance manual’s instructions. Tefal’s IH201840 documentation warns that smaller quantities of liquid may boil dry if left unattended.
Can I use an extension lead with a portable hob?
Use one only if its marked rating can safely accommodate the hob and everything else connected to it. Electrical Safety First warns against exceeding an extension device’s rating or daisy-chaining devices, and says cable reels must be fully unwound to achieve their marked rating. A suitable wall socket is the simpler arrangement where available.
What electrical-compliance details should I check?
For a hob supplied in Great Britain, check the product’s marking and manufacturer information against the applicable electrical-equipment requirements. GOV.UK guidance identifies the Electrical Equipment (Safety) Regulations 2016 as governing electrical equipment placed on the Great Britain market, while Business Companion explains manufacturer marking, conformity and traceability requirements. Northern Ireland has separate provisions, so check the requirements applicable to a delivery there rather than assuming the Great Britain position applies unchanged.
