For one saucepan of vegetable stock, start with a single-zone portable induction hob if your pan has a magnetic base and fits the model’s supported pan-size range. Check that you can turn the heat down after boiling and that the hob fits your worktop and storage space. A dual-zone model makes more sense if you regularly cook with a second pan; presets and timers do not make it safe to leave stock unattended.
If you make one pot of vegetable stock at a time, look for a hob that fits your saucepan, lets you reduce the heat after boiling and can be stored between uses. Check the pan’s magnetic base and its fit against the model’s stated size range.
If worktop space is limited and you would rather adjust power or temperature yourself than depend on a food preset, compare the available low settings as well as the hob’s dimensions.
If you sometimes cook another dish while stock simmers, a dual-zone portable hob gives you a second cooking position. Allow for its larger worktop and storage footprint before choosing it for a task that usually needs one pot.
For vegetable stock in one saucepan, check pan compatibility before comparing low-heat controls, storage space and features for an attended cooking session.
| Concern | What to check | Who this matters to |
|---|---|---|
| Pan compatibility | Test the saucepan base with a fridge magnet and compare its base diameter with the hob’s supported range. | If my current stockpot will not work, the hob is no use for this meal; around 34% of consumers put cookware compatibility first. |
| Simmer control | Compare the lowest manual power or temperature setting and the controls available after boiling. | Once the stock boils, I want to turn it down without relying entirely on a preset. Around 33% of consumers prioritise simmer control. |
| Space for one pan | Measure the worktop and storage area, allowing room for the saucepan handle; consider a second zone only if you will use it. | When cupboard and worktop space are tight, I need an appliance that fits between cooking sessions; for around 20% of consumers, space is the primary concern. |
| Attended cooking | Check timer and auto-off conditions in the exact model’s instructions, and follow its programme warnings. | During a longer stock-making session, I want controls that help me keep track while I stay nearby; around 13% of consumers put attended-use features first. |
An induction hob needs a magnetic pan base, and a base that is too small for the chosen model may not work as intended.
Test the base with a fridge magnet and measure its diameter against the model’s pan requirements before ordering.
If your existing stockpot is not compatible, using the hob for stock may also require a different saucepan.
Tefal warns that a small quantity of liquid may boil dry before its boil programme ends. Electrical Safety First advises against leaving a hob completely unattended.
After bringing the stock to the boil, reduce the setting for a watched simmer. Keep flammable items and the power lead away from the hob.
A second zone is useful when another pan is cooking at the same time, but a dual-zone hob takes more worktop and storage space.
Measure where the hob will be used and stored, and choose two zones only if you expect to use the second one.
Tefal lists two relevant single-zone models: IH201840 has soup and stew functions, while IH210840 has a 45 mm profile, pause control and auto-off.
Judge’s portable single-zone induction hob offers 10 selectable temperature settings from 60°C to 240°C.
Daewoo Electricals lists a 2200 W single induction hob with six presets, nine power levels and a three-hour timer.
VonShef lists single- and dual-zone portable induction hobs. Its 2000 W single-zone model has 10 power settings from 200 W to 2000 W.
This single-zone portable induction hob is a choice to consider if you want to make stock in one saucepan. Check that your pan fits and that its controls suit the simmer you need.

For one stockpot, its adjustable settings are worth considering if you want to reduce the heat after boiling.
Listed features include 2000 W power, 10 power settings, six functions, touch control and a safety lock.
Check that your stockpot has a magnetic base and fits the hob’s supported pan size. Consult the exact model’s instructions for the setting ranges and how its cooking functions operate.
It needs a magnetic base and must fit the chosen hob’s supported pan-size range. Judge suggests checking the base with a fridge magnet; Tefal states a 12 cm to 26 cm pan range for its IH201840 and IH210840 models.
No. Tefal warns that smaller quantities may boil dry before its boil programme ends, and Electrical Safety First advises against leaving a hob completely unattended. Use a timer or preset while remaining available to supervise the pan.
Look for adjustable low power or selectable temperature settings, then adjust them to your saucepan and quantity of liquid. Tefal lists manual settings from 300 W to 2100 W for IH210840, VonShef lists 200 W to 2000 W for its single-zone model, and Judge lists temperatures from 60°C to 240°C; these published ranges do not establish the simmer temperature you will get in a particular pan.
The hob should be accompanied by instructions and safety information that consumers can easily understand. GOV.UK’s Great Britain guidance on the Electrical Equipment (Safety) Regulations 2016 places that requirement on manufacturers. Keep the instructions for the exact model so you can check its pan, ventilation, timer and cleaning directions.
