Choose a single-zone induction hob if your polenta pot has a suitable flat base within the model’s stated size range and adjustable heat matters more than a second cooking zone. A twin solid-plate hob gives you a separately controlled plate for another dish, but its plates remain hot after cooking. Whichever route you choose, plan a stable, heat-resistant position and check the appliance instructions and electrical setup before guests arrive.
If polenta is the only dish needing the extra hob, look for controls that let you reduce the heat while you stir and manage other dinner-party tasks. Check that the timer or pause features you want are present on the exact model.
If a sauce, garnish or other dish needs heat at the same time, two separately controlled plates may matter more than the controls on a single induction zone. The product information lists separate controls for the Russell Hobbs 15199.
If you intend to use a pot you already own, check its induction suitability and measure its flat base before choosing an induction hob. Tefal states different supported pan sizes for its IH201840 and IH210840 models.
Start with the pot you intend to use and the heat controls you need for stirring polenta. Then decide whether another dish needs its own plate and where the hob can operate safely.
| Concern | What to check | Who this matters to |
|---|---|---|
| Lower-heat control | Look beyond maximum wattage to the stated manual power or temperature settings. Tefal gives the IH210840 a 300W–2100W manual range; Judge lists 60°C–240°C selectable temperatures for the JEA90. | When I am stirring polenta while preparing the rest of dinner, I want to be able to turn the heat down after the pot heats up. Around 31% of consumers would put lower-heat control first. |
| Pot compatibility | For induction, check the pot’s suitability and its flat base diameter against the exact model. Tefal specifies 12cm–25cm for the IH201840 and 12cm–26cm induction pans for the IH210840. | If I already have a pot large enough for my guests, I need to know whether its base will work on the hob before choosing one. Pot fit would be the primary concern for around 31% of consumers. |
| A second cooking zone | Decide whether another dish needs heat while the polenta cooks. The product information lists separate controls and 1500W and 750W plates for the Russell Hobbs 15199. | A sauce or side dish may need attention at the same time as the polenta, so one cooking zone could leave me waiting. Around 23% of consumers would prioritise a second zone. |
| Safe temporary setup | Allow for a stable, heat-resistant surface and check the rating of any extension lead against the connected load. Let solid plates cool before moving the hob. | With guests nearby and other appliances in use, I need room to operate the hob and leave it safely after serving. Electrical and heat setup would come first for around 15% of consumers. |
A pot’s rim can look generous while its cooking base falls outside a hob’s supported range. Tefal specifies different ranges for the IH201840 and IH210840.
Measure across the flat underside of your intended pot and check that it is induction-compatible before ordering.
If the pot does not fit, you may need a different induction-compatible pot.
A maximum rating does not tell you which lower settings are available when you want to reduce the heat beneath a thick, stirred dish.
Compare the documented manual power range or selectable temperatures on the exact model, rather than choosing by its maximum rating alone.
A portable hob adds to the load from any other appliances connected to the lead. Electrical Safety First advises against exceeding an extension lead’s maximum current rating.
Check the lead’s marked rating and the connected appliances before cooking; do not daisy-chain extension leads.
The plates on the Russell Hobbs 15199 remain hot after use, according to its Joybuy product listing. That matters when guests are close to the cooking area or you need to clear the worktop.
Keep the hob on a stable, heat-resistant surface and let its plates cool completely before moving or cleaning it.
Tefal’s cited portable induction models offer a single cooking zone with stated manual power and pan-size requirements.
The Judge JEA90 is a single-zone induction option for cooks who want selectable temperature settings.
The Russell Hobbs 15199 offers two solid plates for a polenta pot and a separate heated task.
This portable induction option is for cooking one polenta pot on an extra hob. Check your intended cookware and the appliance instructions before deciding whether it fits your dinner-party setup.

For a polenta pot on an extra cooking zone, check that your cookware is induction-compatible and confirm the supported base size before ordering.
The product name specifies 10 power settings, six functions, touch control and a safety lock. Check the exact instructions for the lowest setting, timer features and electrical setup needed for your plans.
No: an induction pot must meet the hob’s cookware requirements, and its flat base must fit the exact model’s stated range. Tefal specifies an induction-compatible 12cm–25cm base for the IH201840 and 12cm–26cm induction pans for the IH210840.
Check the lead’s marked current rating and the total load connected to it before use. Electrical Safety First advises against exceeding an extension lead’s maximum rating and states that a single socket’s maximum load is 13A, or about 3000W; follow the hob’s own instructions as well.
Wait until it has cooled. The Joybuy listing for the Russell Hobbs 15199 says its plates remain hot after use and should cool completely before the unit is moved or cleaned.
Check the exact model’s instructions rather than assuming that portable means suitable for outdoor use. Tefal’s cited induction-cooker guide describes its appliance as intended for indoor domestic household use only.
