Solo cooks adjusting heat as they go
If you make small batches of onions, several manual settings let you respond as the contents of the pan change. Extra cooking zones may matter less than controls you can adjust during cooking.
Who this suits
Cooks who put the hob away afterwards
A portable hob can serve a compact or temporary kitchen where worktop space needs to be cleared after use. Check its full dimensions against both the cooking area and its storage spot.
People keeping their current frying pan
Before choosing a hob, check that the pan has a magnetic, induction-compatible base. Measure that base—not the rim—and compare it with the requirements for the exact hob model.
What matters when choosing
Start with whether your existing pan will work, then compare the controls you would use during cooking and the space the hob will occupy.
| Concern | What to check | Who this matters to |
|---|---|---|
| Adjustable heat | Look for stated manual power or temperature settings, particularly at the lower end, and controls you can change while cooking. | When a small batch of onions starts to soften, I want to adjust the heat rather than rely on the hob’s maximum output; around 36% of consumers may put manual control first. |
| Pan compatibility | Check that a magnet sticks to the pan’s base, then compare its base diameter with the exact hob’s stated requirements. | If I already have a small frying pan, I want to use it without finding that its base is too small for the hob; roughly 29% of consumers may make existing-pan fit their primary concern. |
| Worktop and storage space | Compare the hob’s external dimensions and cord length with your intended cooking and storage spaces. | I need to clear the worktop after cooking and still have somewhere convenient to put the hob; about 21% of consumers may prioritise its footprint and storage. |
| Safety and support | Check model-specific safety features, instructions and warranty or repair terms. Plan to stay nearby while it is switched on. | For an appliance I use near a hot pan, I want clear operating instructions and support if something goes wrong; around 14% of consumers may put safety features and after-sales support first. |
Buying pitfalls
-
Choosing by maximum wattage alone
Maximum output does not tell you how you can adjust the hob during a slow, one-pan task. Tefal lists nine power levels from 450 W to 2100 W for the IH201840; VonShef lists ten settings from 200 W to 2000 W for its Single Induction Hob. Those are control specifications, not measured pan temperatures.
Compare the selectable settings and change them in response to what is happening in the pan. Continue to watch and stir the onions.
-
Assuming a magnetic pan will fit every hob
A magnetic base can still be outside a particular model’s size requirements. Tefal specifies a 12–25 cm pan-base range for the IH201840, while Judge says bases under 12 cm are unsuitable for the JEA90.
Measure the flat base rather than the pan rim, and compare it with the exact model’s requirements before ordering.
If your current pan does not meet those requirements, you may need a different induction-compatible frying pan.
-
Treating a timer as permission to leave the hob on its own
Electrical Safety First advises against leaving electrical appliances switched on and unattended. A timer or automatic shut-off is an additional feature, not a substitute for watching a hot pan.
Stay nearby while cooking. Follow the appliance instructions for ventilation, cooling and cleaning before putting it away.
-
Relying on a listing title for electrical-product details
A model name and wattage do not establish which product information applies to a particular listing. Electrical-equipment provisions also differ between Great Britain and Northern Ireland.
Check the exact model’s instructions, voltage information, responsible seller and conformity documentation applicable where it will be supplied.
Brands to consider
Tefal
The portable IH201840 has published control and pan-size specifications useful for checking a one-pan setup.
- Tefal specifies nine power levels from 450 W to 2100 W, a two-hour timer and a compatible pan-base range of 12–25 cm.
- It provides one cooking zone, so it will not accommodate a second pan at the same time. Tefal’s stated ten-year repairability commitment should be distinguished from warranty cover.
Judge
The portable JEA90 offers selectable temperature settings and documented cookware requirements.
- Judge specifies ten temperature settings from 60 °C to 240 °C and external dimensions of 31 × 27 × 5 cm.
- The JEA90 manual identifies pan bases below 12 cm as unsuitable. Check that your existing frying pan meets this minimum.
VonShef
Its portable Single Induction Hob offers both power and temperature settings for a one-pan cooking setup.
- VonShef states ten power settings from 200 W to 2000 W, ten temperature settings from 60 °C to 240 °C and a timer.
- Confirm your pan’s compatible base diameter for the exact model before buying; an induction symbol alone does not settle its fit.

Frequently asked questions
Will my current frying pan work on a portable induction hob?
It can work if it has a magnetic, induction-compatible base that meets the exact hob’s size requirements. Judge recommends checking whether a fridge magnet sticks to the base and says bases under 12 cm are unsuitable for its JEA90. Tefal specifies a 12–25 cm base range for its IH201840; measure the base rather than the rim.
Do I need the highest wattage to caramelise onions?
No: prioritise settings you can adjust as the onions cook rather than maximum output alone. Tefal specifies nine power levels from 450 W to 2100 W for the IH201840, while VonShef specifies ten settings from 200 W to 2000 W for its Single Induction Hob. These ranges do not guarantee a particular temperature in your pan.
Can I leave onions cooking if the induction hob has a timer?
No. Electrical Safety First advises against leaving electrical appliances switched on and unattended. Keep an eye on the pan and adjust the heat as needed; a timer is not a replacement for supervision.
How should I clean and store a portable induction hob?
Let the hob and pan cool, unplug the appliance before cleaning and follow its model-specific instructions. Tefal advises using a damp soft cloth on the IH201840’s ceramic plate. Check that ventilation openings remain clear when the hob is in use.
Can someone with a pacemaker use a portable induction hob?
Do not assume that every model is suitable. Lakeland warns that its Smart Touch Induction Hob is not suitable for someone with a pacemaker. Check the warning for the exact appliance and seek appropriate medical advice before purchase or use.
