Who this choice suits

Regular low-and-slow cooks

If you often caramelise onions, adjustable lower heat, a frying pan that fits the hob and a timer may matter more to you than the highest output setting.

Small-kitchen extra-burner buyers

A portable hob can provide a temporary cooking zone or be put away between uses. Check its storage dimensions alongside the supported diameter of the pan you intend to use.

First-time induction buyers

Before choosing an induction model, check that your pan has a magnetic base. For use in Great Britain, check the exact product’s plug and applicable market-marking information too.

What to check when buying

For a long onion cook, start with adjustable heat and pan-base fit. Then check whether the hob stores conveniently and can be connected safely where you plan to use it.

Concern What to check Who this matters to
Lower-heat control Compare manual power steps, the stated lower setting and timer controls; continue to stir and supervise the onions. If I cook onions slowly and often, I want to turn the heat down in stages rather than rely on a high-output preset. Roughly 42% of consumers put controllable heat first.
Storage and pan fit Measure the storage space and compare the pan’s base diameter with the exact model’s supported range. When the hob needs to go back into a cupboard, I need it to fit the space without ruling out my frying pan. Compact storage and pan fit come first for around 33% of consumers.
Cookware and electrical set-up Check the pan base with a magnet, the exact GB-market version and plug, and the rating of any extension lead. Before switching to induction, I need my existing pan and power connection to be suitable. For roughly 25% of consumers, compatibility and electrical safety are the primary concern.

Buying pitfalls

  • Assuming every frying pan works on induction

    An induction hob needs a pan with a magnetic base, and supported pan diameters vary by model. Tefal UK specifies 12–26 cm for the IH201840, while CASO Design specifies 12–22 cm for the ProSlim 2000.

    Test the pan base with a magnet and compare its base diameter—not just its rim—with the exact hob’s specification.

    If your existing pan is incompatible or outside the supported size range, using an induction hob may require another pan.

  • Choosing by maximum wattage alone

    A high maximum output does not establish how manageable a hob will be at the lower settings needed for a long onion cook. A timer or cooking preset does not replace heat adjustments and supervision.

    Compare the stated manual settings and timer controls, then plan to reduce the heat after warming the pan and keep stirring as needed.

  • Overloading a lead or leaving the hob unattended

    Electrical Safety First warns that an extension lead’s connected load must stay within its marked rating; some leads and cable reels have lower ratings than others. Hot surfaces, water and trailing leads add practical risks in a kitchen.

    Use a sound wall socket where possible. If an extension lead is necessary, check its rating and everything connected to it, keep the lead clear of heat and water, and remain present while cooking.

  • Assuming any plug and market version will do

    The plug and product-marking details need to match the version you buy. CASO Design’s ProSlim 2000 manufacturer page specifies a Type C plug; where a listing does not identify the plug, confirm it with the seller before buying.

    Confirm the exact unit’s plug and supplier information before ordering. For use in Great Britain, check its applicable UKCA or CE marking information; Northern Ireland has separate product-marking arrangements.

Relevant portable-hob brands

Tefal

The Everyday IH201840 illustrates a single-zone induction option for cooks comparing manual settings with frying-pan size.

  • Tefal UK specifies nine power levels from 450 W to 2100 W, six programmes, a digital display and a 12–26 cm cookware range for this model.
  • The pan must still be induction-compatible; the stated settings are specifications, not a cooking-test result for onions.

Daewoo

The SDA2771GE is a single-zone induction option for buyers who also want a higher maximum output and a longer timer.

  • Daewoo Electricals specifies 2200 W maximum output, nine power levels, a three-hour timer, overheat protection and a child lock for this model.
  • Maximum output and safety features do not establish how it performs when slowly caramelising onions or remove the need to supervise cooking.

CASO Design

The ProSlim 2000 is worth considering when compact storage matters alongside adjustable induction settings.

  • CASO Design specifies a 28 mm height, ten power levels, ten temperature levels and a 12–22 cm cookware range for this model.
  • The manufacturer specifies a Type C plug. Confirm the exact UK-retail unit’s plug and market information before purchase, as well as whether its cookware range fits your pan.

Frequently asked questions

Will my frying pan work on a portable induction hob?

It needs a magnetic base and a base diameter within the exact hob’s stated cookware range. Tefal UK advises checking for firm attraction with a magnet; measure the base rather than relying on the pan’s rim diameter.

Is a higher wattage rating better for caramelising onions?

Not necessarily: maximum wattage describes top-end output, not how a hob handles a long cook at lower heat. Compare manual settings and keep adjusting the heat while you stir; Tefal UK specifies nine levels from 450 W to 2100 W for the IH201840, while Daewoo Electricals specifies nine levels and a three-hour timer for the SDA2771GE.

Can I use a portable hob with an extension lead?

Only if the lead is suitable for the hob and the combined load of everything connected stays within its marked rating. Electrical Safety First notes that some extension leads and cable reels are rated at 10 A or less; check the particular lead rather than assuming it can carry a high-power appliance.

What product marking should I check for use in Great Britain?

Check the applicable marking information for the exact GB-market product rather than assuming its plug or marking from a similarly named version. Department for Business and Trade guidance updated in August 2026 states that Great Britain continues to recognise CE marking alongside or instead of UKCA marking in relevant cases; Northern Ireland’s arrangements can differ.
