Who needs a portable hob?

Gentle-sauce cooks

If you regularly make cheese, milk or cream sauces, look for a documented low setting, keep-warm mode or temperature-control feature. Check the controls on the particular model rather than relying on its maximum output.

Households with little worktop space

A movable cooking zone may suit a kitchen where the hob needs to be stored after use. Measure the space it will occupy while cooking, not just the space needed to put it away.

Cooks keeping an existing saucepan

If you want to use a saucepan you already own, check its base before choosing induction. AEG advises that induction cookware needs a magnetic base; a non-induction hot plate may be a more practical route for a non-magnetic pan.

What matters when choosing?

For cheese sauce on a small worktop, decide whether your saucepan can be used on induction, then compare gentle-heat controls and the room each hob needs during cooking.

Portable induction

Choose it when: Your flat magnetic saucepan fits the model’s stated pan-size range and you want documented power, keep-warm or temperature controls.

Trade-off: A non-magnetic saucepan will not work on induction, and a small pan must meet the particular hob’s size requirements.

Thermostatic electric hot plate

Choose it when: Keeping a non-magnetic saucepan is more important than having induction-specific controls.

Trade-off: An adjustable thermostat alone does not establish how gently the exact hot plate will heat sauce; check its instructions and dimensions.

Concern What to check Who this matters to
Gentle sauce control Look for a stated low setting and check how keep-warm, slow-cook or probe modes operate. Tefal specifies seven manual levels from 300W to 2100W for IH210840; Smeg lists probe modes for PIC01BLMUK. When melting cheese or holding a finished sauce, I want control beyond a high maximum setting. Around 42% of consumers would put gentle sauce control first.
Worktop and storage fit Check the full width and depth, the required clearances and where the lead will run. Tefal’s stated 45mm thickness for IH210840 describes storage height, not its in-use footprint. If the hob must come out only when needed, I need it to fit safely while the pan is on it and to be manageable to store afterwards. Worktop and storage fit would come first for around 33% of consumers.
Saucepan compatibility For induction, test the flat pan base with a magnet and compare its base diameter with the exact hob’s permitted range. Tefal states 12cm to 26cm for IH210840. I would rather keep my current saucepan than change cookware to suit a new hob. That makes saucepan compatibility the primary concern for around 25% of consumers.

Mistakes to avoid

  • Ordering induction before checking the pan

    An induction hob needs suitable magnetic cookware. The saucepan’s rim can also make it look larger than the base that sits on the cooking zone.

    Test the base with a magnet, measure its diameter and compare it with the exact hob’s stated range before ordering.

  • Using maximum wattage as a measure of gentle control

    A maximum rating does not tell you the lowest selectable setting or how a thermostat operates. Tefal states a manual range for IH210840, while Smeg describes probe modes for PIC01BLMUK; Zuvo describes an adjustable thermostat on its cited hot plate.

    Compare the controls and operating instructions of the models you are considering rather than judging them by maximum output alone.

  • Confusing slim storage with safe placement

    A hob that is easy to store still needs a suitable surface and room for the pan and lead during use. Northumberland Fire and Rescue Service advises keeping cloths away from the hob and electrics away from water.

    Measure the intended worktop area and follow the exact appliance’s placement and clearance instructions.

  • Assuming every portable hob listing is electrically safe

    A UK Office for Product Safety and Standards report dated 11 August 2025 identified a serious fire risk involving the plug fuse of one portable induction cooker. That finding concerns the product in that report, not every induction hob.

    Check applicable product-safety notices, the seller and supplied instructions. Do not use an appliance with a damaged lead or plug.

Brands to consider

Tefal

The Everyday Slim IH210840 is an induction option with documented controls and pan-size requirements.

  • Tefal specifies a 45mm thickness, seven manual levels from 300W to 2100W, slow-cook and keep-warm functions, and an accepted induction-pan range of 12cm to 26cm for this model.
  • It still requires compatible magnetic cookware. Its stated thickness alone cannot tell you whether it fits your worktop during use.

Smeg

The PIC01BLMUK is a portable induction option for cooks interested in temperature-led control.

  • Smeg specifies a temperature probe with target and timer modes, keep-warm, nine power levels and boost for this model.
  • Compatible induction cookware remains necessary. Check the model’s pan-size requirements and dimensions before choosing it for a small worktop.

Zuvo

Zuvo’s cited 1500W single hot plate offers a conventional electric alternative to induction.

  • Zuvo describes this cast-iron-plate model as having an adjustable thermostat.
  • Check the exact hot plate’s dimensions and operating instructions before relying on it for your available space or preferred sauce-making method.

Common questions

Can I use my existing saucepan on a portable induction hob?

Yes, if its base is suitably flat and magnetic and its diameter meets the particular hob’s requirements. AEG recommends checking the base with a magnet; Tefal specifies a 12cm to 26cm induction-pan range for the Everyday Slim IH210840.

Which controls should I look for when making cheese sauce?

Look for documented low-power adjustment or a gentle cooking mode rather than choosing by maximum wattage. Tefal specifies a 300W to 2100W manual range for IH210840, while Smeg lists nine power levels and keep-warm for PIC01BLMUK. Start gently and stir; neither specification guarantees a particular sauce result.

Can I leave a portable hob running while I do something else?

Do not leave it unattended while it is in use. Tefal’s guidance says to remain with the appliance even when heating liquid, and Northumberland Fire and Rescue Service advises turning down the heat or removing pans if you need to leave the kitchen.

What should I check for electrical safety?

Check applicable product-safety notices, the seller, the supplied instructions and the condition of the plug and lead before use. A UK Office for Product Safety and Standards report dated 11 August 2025 identified a serious plug-fuse fire risk in one portable induction cooker; it does not establish the status of a different model.

Where should a portable hob sit in a small kitchen?

Put it on a flat, stable, heat-resistant surface in accordance with its instructions, leaving the required space around it. Keep the lead away from water and cloths away from the hob, as Northumberland Fire and Rescue Service advises.
