Who is a portable hob for?

Small-batch custard makers

If you usually make one serving in a small saucepan, one cooking zone may be enough. Look for heat settings you can adjust while stirring, rather than choosing on fast-heating claims alone.

Cookware-first buyers

If you want to keep using a saucepan you own, check its base before choosing a hob. Bosch advises using ferromagnetic cookware for induction; the Cooks Professional single ceramic model is stated to accept a wider range of pan materials.

Compact-kitchen cooks

A portable cooking zone may suit you if you need to put the hob away after use or add temporary cooking space, provided its footprint and required worktop position suit your kitchen.

What matters when choosing?

Portable induction

Choose it when: Your saucepan has an induction-compatible magnetic base and its base diameter fits the hob’s stated range.

Trade-off: Bosch says induction requires ferromagnetic cookware, so a non-magnetic pan needs a suitable magnetic base or a different hob.

Portable ceramic

Choose it when: Keeping an existing non-induction saucepan is the deciding factor; Cooks Professional states that its single ceramic model accepts aluminium and copper as well as cast iron and stainless steel.

Trade-off: The ceramic cooking surface heats during use and remains hot afterwards, so allow for residual heat when handling and cleaning it.

For a one-person batch, the most useful checks are gentle heat adjustment, a workable one-pan setup and compatibility with the saucepan you intend to use. Which? treats maintaining a gentle simmer as a separate hob-performance consideration from heating quickly.

Concern What to check Who this matters to
Gentle heat adjustment Look for manual heat settings and check the model’s guidance on low-heat cooking; maximum wattage does not establish how steadily it cooks. I need to lower the heat while stirring a small batch without relying on a fast-boil setting; around 42% of consumers would put gentle heat adjustment first.
Compact, one-pan setup Check the hob’s footprint, cord reach and suitable worktop position, and decide whether you need to cook anything else at the same time. When I only use one saucepan, I want a hob I can position and put away conveniently; roughly 33% of consumers would make the compact setup their primary concern.
Pan compatibility and care Check the pan-base material and diameter against the exact hob’s requirements; follow its instructions for handling and cleaning the surface. Keeping my existing saucepan matters more to me than changing cookware, and I need to account for a hot surface after cooking; about 25% of consumers would prioritise pan compatibility and care.

Buying mistakes to avoid

  • Assuming every saucepan works on induction

    Induction needs a ferromagnetic pan base. Bosch notes that copper and aluminium cookware without a suitable magnetic base will not work for induction.

    Check the pan’s induction marking or whether a magnet adheres to its base, then compare the base diameter with the hob’s stated range.

  • Choosing by maximum wattage alone

    A high maximum setting does not establish how the hob behaves at gentle heat. Which? considers the ability to maintain a simmer separately from quick heating.

    Check the manual heat adjustments and the model’s instructions, then use your recipe’s stirring and heat guidance when cooking custard.

  • Measuring the saucepan rim instead of its base

    The Tefal IH201840 states a compatible pan range of 12–26 cm, while the Cooks Professional ceramic example has a 17.5 cm zone. Those figures describe different products and should not be treated as interchangeable limits.

    Measure the flat base of the saucepan you will use and compare it with the requirements for the exact hob.

  • Assuming a UK listing settles regional suitability

    GOV.UK publishes separate electrical-equipment guidance for Great Britain and Northern Ireland because some provisions differ.

    Before ordering a plug-in hob, check the seller’s information for your delivery region, the supplied connection arrangement and the product instructions.

Relevant brands for reference

Tefal

Its IH201840 is a portable induction example with selectable settings for buyers considering a single cooking zone.

  • Tefal states nine power levels, six cooking functions and a compatible pan range of 12–26 cm for the IH201840.
  • It requires induction-compatible cookware; the number of settings does not establish how it will handle a particular custard recipe.

Cooks Professional

Its single ceramic hob is a reference point for buyers who want dial operation and to keep using non-induction pans.

  • Cooks Professional states that this model accepts cast iron, stainless steel, aluminium and copper cookware.
  • Its stated dial range is not a measured guarantee of gentle custard cooking, and the surface remains hot after use.

Bosch

Bosch’s cookware guidance is useful when deciding whether an existing saucepan can be used on induction.

  • Bosch advises using ferromagnetic cookware and matching the pan base to the cooking zone.
  • That guidance helps with compatibility; it does not identify a particular Bosch hob for a one-person batch of custard.

This portable induction option is relevant if you want adjustable settings for a small batch and have an induction-compatible saucepan. Check the pan-size guidance and low-heat operation for the exact model before deciding whether it suits your custard recipe.

ochama 2000 W portable induction hob

ochama 2000 W Portable Induction Hob

Consider this portable induction hob if your custard saucepan has a magnetic induction-ready base.

The product name specifies 2000 W, 10 power settings, six functions, touch controls and a safety lock. Those settings do not establish the lowest stable heat for your saucepan.

Check the supported pan-base diameter, low-heat instructions and electrical information for your delivery region before ordering.

Questions about cooking custard on a portable hob

Can I use a small custard saucepan on an induction hob?

Yes, if its base is induction-compatible and falls within the hob’s stated pan-size range. Bosch advises matching the base to the cooking zone; for example, Tefal states a compatible pan range of 12–26 cm for its IH201840.

Is ceramic a better fit for an aluminium or copper saucepan?

A portable ceramic hob may let you keep using that saucepan if its base is not induction-compatible. Cooks Professional states that its single ceramic model accepts aluminium and copper; Bosch says induction cookware needs a suitable ferromagnetic base, so check the pan’s construction rather than its material name alone.

Does a higher wattage make it easier to cook custard?

Not necessarily: maximum wattage does not tell you how well a hob maintains gentle heat. Which? treats simmering as a distinct performance consideration, so check the available adjustments and use the heat and stirring instructions for your recipe.

What should I check before buying a plug-in hob for use in the UK?

Check that the seller identifies the appliance as suitable for your delivery region and that its instructions and connection arrangement suit your intended use. GOV.UK provides separate electrical-equipment guidance for Great Britain and Northern Ireland, where some provisions differ; a UK-facing listing alone does not settle the requirements for an individual product.

Should I check for recalls on a portable hob?

Yes, check recall information against the exact brand and model, particularly if you notice a fault. Electrical Safety First directs consumers to the Office for Product Safety and Standards for current product-recall information.
