Buying a multi-cooker: how to compare functions, capacity and safety features

A multi-cooker can combine pressure cooking, braising, steaming, slow cooking and keeping food warm in one appliance. This is practical for families, working professionals, meal-prep users, singles and students – provided the model suits your actual cooking habits.

However, buying the wrong model can lead to unnecessary costs. Three common pitfalls are particularly important:

  • Too many programmes without a practical use: An appliance with a 7-in-1 or 9-in-1 function is not automatically more useful if you mainly prepare rice, soups or stews.
  • Confusing total volume with usable capacity: A 6-litre pressure cooker may hold 6 litres internally, but it must not be filled completely when pressure cooking. The Cecotec Programmable Cooker Model D, for example, is listed with an internal volume of 6 litres but a usable capacity of 5 litres.
  • Unclear hob and cleaning compatibility: A pressure cooker for induction must be explicitly suitable for induction hobs. With electric appliances, you should check the mains plug, power rating, removable parts and cleaning instructions in the user manual.

The most important buying parameters for a multi-cooker

1. Choose the capacity to suit your household size

The stated litre capacity does not automatically indicate how much food can be prepared using every function. Pressure cooking usually requires some free space. The maximum markings inside the pot and the manufacturer’s specifications are therefore the key points to consider.

As a practical guide:

  • 1.8 litres: for one person or small portions, for example in student accommodation.
  • 3.8 litres: for singles, couples and smaller meal-prep quantities.
  • 4.5 to 5.7 litres: for several portions, small families or regular batch cooking.
  • 6 to 7.6 litres: for families, guests and larger batch-cooking quantities.

According to its product description, a 5.7-litre electric pressure cooker may be suitable for up to six people. However, the actual quantity depends on the recipe, ingredients and permitted filling level.

2. Choose cooking functions carefully

Depending on the model, a programmable cooker may offer pressure cooking, slow cooking, sautéing, steaming, rice cooking, yoghurt making or a keep-warm function. Check whether the functions can be used independently and whether the time and temperature can be adjusted.

A 7-in-1 multi-cooker, for example, is suitable for households that want to combine several cooking methods in one appliance. However, if you expect crispy results, look for a model with a separate air-fryer lid or hot-air function. A traditional pressure cooker is not a substitute for an air fryer.

3. Safety features and materials

For pressure appliances, important features include a securely locking lid, controlled steam release, a pressure indicator and protection against opening while residual pressure remains. The appliance should only be used in accordance with the user manual.

With a stainless-steel pressure cooker, material specifications such as 18/10 stainless steel are useful indicators. The base is also important when using the cooker on a hob. A multi-layer or encapsulated base can distribute heat across gas, electric, ceramic and induction hobs. However, this does not mean that every appliance is automatically suitable for all hob types – the manufacturer’s specification remains decisive.

Cleaning also deserves attention: dishwasher-safe inner pots and lid components save time. Sealing rings, valves and handles may require separate care and regular visual inspection, depending on the model.

Tips for safe and economical use

Before using the appliance for the first time, read the user manual and check the sealing ring, valve and lid mechanism. Pressure appliances are also subject to these basic rules:

  • Never exceed the maximum filling level.
  • Do not force the lid open while residual pressure remains.
  • Do not touch the steam outlet during operation.
  • Regularly check the sealing ring and valve for dirt or wear.
  • Do not immerse the electrical housing in water.
  • With a hob model, position the pot so that it matches the cooking zone.

When it comes to running costs, power rating, cooking time and frequency of use are the main factors. Figures quoted by manufacturers, such as “up to 70 per cent shorter cooking time” or “up to 80 per cent less energy”, are product-specific claims and depend on the recipe, starting temperature and comparison method. For a realistic comparison, consider the electricity consumption of your specific cooking process.

Frequently asked questions about multi-cookers

Is a multi-cooker suitable for a family?

Yes, models between 5.7 and 7.6 litres may be suitable for preparing several portions. The key factors are usable capacity, filling markings and the size of your usual meals. A pressure cooker of around 6 litres may be sufficient for a family of four; for meal prep or guests, a larger model may be more suitable.

How long does an electric pressure cooker last?

Its lifespan depends on how it is used, how well it is maintained and the condition of the sealing ring, valve and coatings. A stainless-steel inner pot is generally less susceptible to scratches than coated versions. Wear parts should be checked and replaced when necessary in accordance with the manufacturer’s instructions.

Is an air-fryer multi-cooker worth it?

That depends on the space available and the dishes you prefer to cook. If you regularly want to pressure cook and also prepare food with hot air, a combination appliance can be useful. If you only cook soups, rice or stews, you may not need the additional air-fryer function.
