Solo cooks needing an extra hob
If you cook in a small, shared or temporary kitchen, a storable cooking zone may make more sense than changing the main hob.
Who this choice affects
Sauce makers prioritising gentle adjustment
When you are warming and melting ingredients in a small saucepan, the lower settings matter more to your choice than maximum output alone.
Kitchen renovators replacing a main hob
If the same appliance must handle everyday multi-pan cooking, compare built-in formats and their model-specific connection and installation requirements.
What matters when choosing
Start with heat adjustment and saucepan fit for the sauce itself. A built-in hob becomes relevant when you also need to replace your main cooking surface.
| Concern | What to check | Who this matters to |
|---|---|---|
| Gentle heat adjustment | Compare the lowest selectable power or temperature setting and how you adjust it; maximum wattage alone does not answer this question. | If I am melting cheese in a small sauce, I want to adjust the heat without relying on maximum output. Around 46% of consumers put gentle heat control first. |
| Compact one-pan cooking | Check whether a portable format suits your space and whether the saucepan’s magnetic base falls within the hob’s supported diameter range. | I need an extra surface that I can put away after making one saucepan of sauce. For around 36% of consumers, that compact, temporary setup is the primary need. |
| Main-hob replacement | Check zone layout, connection type, worktop cut-out and ventilation requirements against the exact model’s installation instructions. | If the hob must also cook everyday meals in several pans, I need a permanent setup that fits my kitchen. That wider cooking need comes first for around 18% of consumers. |
Buying pitfalls
-
Choosing by maximum wattage alone
A high maximum setting does not tell you how the hob adjusts at lower heat. Tefal UK Shop lists the IH201840’s nine power levels as ranging from 450W to 2100W; CASO Design lists ten power levels and temperature settings from 60°C to 240°C for the ProSlim 2000.
Compare the lowest selectable setting and controls for the exact model. Keep stirring and supervising the sauce rather than treating a setting as an automatic cooking programme.
-
Assuming every small saucepan works on induction
Induction needs a magnetic cookware base, and the pan’s base diameter must suit the hob’s stated range. The measurement across the top of the pan is not the measurement to rely on.
Test the base with a magnet and compare its diameter with the exact hob’s requirements.
An incompatible saucepan may need replacing before you can use it on induction.
-
Ordering a built-in hob before checking the kitchen
Connection and fitting requirements vary by model. Bosch advises checking the installation instructions for the chosen hob, while AEG specifies a hardwired-only connection for the NII84B10AB.
Check the cut-out, worktop and ventilation requirements, as well as the electrical connection, before ordering.
An unsuitable opening or connection can mean additional installation work.
-
Assuming an online electrical listing establishes safety
A 2025 Office for Product Safety and Standards report identified a serious fire risk involving the plug on one specific induction cooker. It does not describe all portable induction hobs.
Check the exact product against official safety alerts, and inspect its plug and lead before use, as Electrical Safety First advises.
Brands to consider
Tefal
The portable, single-zone IH201840 is relevant when you need an extra cooking surface rather than a new main hob.
- Tefal UK Shop lists nine power levels from 450W to 2100W and a compatible pan-base range of 12cm to 25cm for this model.
- Its single zone does not provide space for several pans at once.
CASO Design
The portable ProSlim 2000 is another option for a temporary or additional cooking zone.
- CASO Design lists ten power levels, settings from 60°C to 240°C and a recognised-pan range of 12cm to 22cm.
- Check that your small saucepan’s base falls within that model’s stated range.
Bosch
The built-in PUG61RAA5B is relevant when the purchase is also a permanent main-hob replacement.
- Bosch describes this as a four-zone, 13A plug-in induction hob with power management.
- A plug-in connection does not remove the need to check the exact model’s worktop and installation instructions.
AEG
The built-in NII84B10AB is relevant to a wider main-hob replacement, not just one small sauce.
- AEG lists four zones and a Boil Sensor intended to bring boiling water down to a controlled simmer.
- This model is hardwired-only, and its water-boiling function should not be treated as an automatic cheese-sauce setting.

ochama 2000W Portable Induction Hob
The portable format suits an extra cooking surface for a small sauce.
Its product title specifies 2000W, ten power settings, touch controls and a safety lock. Before buying for your saucepan, check the lowest selectable setting, supported magnetic pan-base diameter and plug details.
Questions about small-sauce cooking
Will my existing small saucepan work on an induction hob?
It needs a magnetic base that fits the hob’s supported pan-size range. Electrolux recommends checking whether a magnet holds firmly to the base; measure that base, rather than the pan’s wider rim, against the exact hob’s requirements.
What pan-base size do the cited portable models accept?
Tefal UK Shop lists 12cm to 25cm for the IH201840, while CASO Design lists a 12cm to 22cm recognised-pan range for the ProSlim 2000. Check your own saucepan’s magnetic base against the model you choose.
Do I need a built-in hob just to make cheese sauce for one?
No: a portable single-zone hob is a proportionate option when one saucepan and a storable surface meet your needs. Consider a built-in model when it will also replace your main hob, and check its fitting and connection requirements before ordering.
What should I check before using a portable induction hob?
Inspect the plug and lead, follow the model’s electrical and placement instructions, and supervise it while cooking. Electrical Safety First advises checking appliance leads before use; official safety alerts can also be checked for the exact product.
What after-sales terms are worth checking?
Check the exact model’s warranty, repair and spare-parts terms rather than assuming one policy covers every product from a brand. Tefal UK Shop states 10-year repairability for the IH201840; that product statement is not itself a universal warranty term.
