Who this choice affects

Shared-kitchen cooks needing another burner

If the communal hob is busy, a personal burner could give you space for a one-pot meal. Check your accommodation rules, the available socket and clear worktop space before buying one.

Soup cooks with induction-ready saucepans

If you have a magnetic, flat-bottomed saucepan that meets a hob's size requirements, adjustable heat settings can help you move from boiling to a gentler simmer.

Cooks relying on shared cookware

If the available pans are glass, ceramic or non-magnetic metal, cookware compatibility may decide whether induction is practical. Check the pan base before choosing the hob.

What to check before choosing

Portable induction hob

Consider it when: A personal appliance is permitted and you have a compatible saucepan and suitable socket for one-pot cooking.

Trade-off: An unsuitable shared saucepan may not heat at all; a soup preset still needs your attention.

Portable ceramic hob

Consider it when: A personal appliance is permitted but the pans you need to use are unsuitable for induction.

Trade-off: The cooking zone retains heat after switch-off, so allow for it when handling the pan and cleaning up.

Supplied communal hob

Use it when: An extra appliance is not permitted or you cannot give one a suitable socket and clear worktop.

Trade-off: You may need to wait for a cooking zone at busy times.

Start with permission and the socket arrangement. Then decide whether your saucepan, available space and need for another cooking zone justify a personal hob.

Concern What to check Who this matters to
Permission and socket safety Confirm the accommodation rules and the hob's rated load against the intended socket arrangement. If I cannot use a personal hob where I live, its cooking features will not help me; around 33% of consumers put permission and socket safety first.
Simmer control and cookware Check adjustable low settings and, for induction, the saucepan's magnetic base and permitted diameter. I need to bring lentils to the boil, then keep the soup at a manageable simmer with a pan the hob will recognise. Around 27% of consumers make cooking control and pan compatibility their primary concern.
Space and cleaning Compare the hob's dimensions with clear worktop and storage space; follow its cooling and cleaning instructions. In a crowded shared kitchen, I need somewhere to put the hob away and a practical way to clean up soup splashes; roughly 20% of consumers prioritise space and cleaning.
Cooking-zone capacity Decide whether one saucepan is enough or whether you need another zone for a dish at the same time. If others are using the communal cooker, I may need another active zone rather than a replacement for the whole hob. About 20% of consumers put extra cooking capacity first.

Buying mistakes to avoid

  • Buying induction before checking the saucepan

    Induction requires a suitable magnetic base. Judge also specifies a minimum pan-base diameter of 12 cm for its JEA90, so even an induction-ready pan must meet the chosen model's size rules.

    Check the pan and the exact hob manual before ordering. A fridge magnet sticking to the base is a useful initial check, not a substitute for the manufacturer's cookware guidance.

    If the saucepan is unsuitable, you may need a compatible one to use the hob.

  • Assuming an extension lead can take another hob

    Other appliances running in a shared kitchen can add to the electrical load. Electrical Safety First warns against overloading sockets and daisy-chaining extension leads.

    Check the hob's rating and the loads already connected. Use a suitable wall socket where the appliance instructions and accommodation rules allow it.

  • Treating a timer as permission to leave soup cooking

    Tefal warns that a programmed boil can vary with the pan and quantity, while Greater Manchester Fire Rescue Service advises against leaving cooking unattended.

    Stay with the pan, turn the heat down when the soup reaches the boil and use any timer as an additional reminder.

    A pan that boils dry or boils over may also leave you with extra cleaning in the shared kitchen.

  • Ordering before checking where the hob can go

    Permission for personal cooking equipment depends on the accommodation provider, and a portable hob still needs a suitable place to operate and be stored.

    Ask the provider about the specific appliance, then check the worktop, required clearances and storage space against its instructions.

Relevant brands for reference

Tefal

Tefal's Everyday Induction Hob IH201840 is a portable induction model with nine power levels, soup and stew functions, and a stated pan diameter range of 12–26 cm.

  • The published power levels and cooking functions offer ways to adjust heat while making soup.
  • It requires induction-compatible cookware. Tefal warns that programmed boiling varies with the pan and quantity and that cooking must not be left unattended.

Daewoo

Daewoo lists the single-zone induction SDA2771 at 2200 W, with nine power levels, a soup preset and dimensions of 35 × 28 × 5.5 cm.

  • Its published footprint and controls give you specific details to compare with your worktop and one-pot cooking needs.
  • The preset is not an independently measured simmer result; the model still needs compatible cookware and permission for use in your accommodation.

Judge

Judge specifies its portable induction JEA90 at 2000 W, with ten selectable temperatures from 60°C to 240°C and dimensions of 31 × 27 × 5 cm.

  • The published temperature settings provide a manual-control option to assess for soup cooking.
  • Judge requires magnetisable cookware and advises against pan bases smaller than 12 cm; other pan materials need a suitable induction base.

Joybuy options for one-pot soup

This portable induction option is for cooking soup in one saucepan, provided a personal hob is permitted and your cookware and socket arrangement are suitable.

ochama 2000W portable induction hob

ochama 2000W Portable Induction Hob

  • Rated at 2000 W, with touch controls and a glass panel.
  • Requires ferromagnetic cookware. Check your saucepan's base diameter against the hob's requirements.
  • Confirm the footprint, operating clearances, accommodation permission and socket arrangement before use. Stay with the soup while it cooks.

Common questions

Can I bring a personal electric hob into a shared kitchen?

Check with your landlord, accommodation provider or property manager before buying one. Permission depends on your particular residence conditions and the appliance; the University of Surrey, for example, sets conditions for certain personal kitchen appliances rather than granting blanket permission.

Will my saucepan work on a portable induction hob?

It will work only if its base is induction-compatible and meets the chosen hob's size requirements. Judge specifies magnetisable cookware and a base diameter of at least 12 cm for its JEA90; check the requirements for any other model separately.

Can I plug a portable hob into an extension lead?

Do not assume an extension lead is suitable. Electrical Safety First says a single socket is typically limited to 13 A, or about 3 kW, and advises checking an extension lead's rating and avoiding daisy-chaining. Compare the hob's rating with other connected loads and follow its instructions for the socket arrangement.

Can I leave lentil soup cooking if the hob has a timer or soup preset?

No: a timer or preset does not replace supervision. Greater Manchester Fire Rescue Service advises against leaving cooking unattended, and Tefal warns that boiling behaviour can vary with the pan and quantity. Stay nearby and reduce the heat when the soup reaches the boil.
