Buying electronics and household appliances online: what to consider

Buying electronics and household appliances online involves more than comparing prices. Compatibility, capacity, energy consumption, what’s included and whether the features suit your daily routine are all important. A low price can prove impractical if accessories are missing, the appliance doesn’t fit the space you have in mind or it comes with significant ongoing costs.

Common buying mistakes with electronics and household appliances

1. Marketing terms are mistaken for measurable features

Terms such as “smart”, “Premium” or “AI” say little on their own about practical benefits. Instead, check the specific details: number of programmes, app compatibility, noise level, energy consumption, charging time or included accessories.

For Wi-Fi-enabled household appliances, it’s also important to check which functions you can actually control via the app. A Wi-Fi connection might only provide status updates, for example, while other models also let you control programmes and start times or use voice commands.

2. Compatibility is checked too late

A screen protector must be an exact match for your model. A screen protector for an older iPhone may not be suitable because of the camera cut-out, display edges or sensors. Attachments, spare parts and connectors also vary between electric toothbrushes, breast pumps and washing machines.

3. Ongoing costs are overlooked

With an electric toothbrush, it’s not just the purchase price that counts. You should also consider compatible brush heads and what’s included in the set. When choosing a washing machine, washer-dryer or heat pump tumble dryer, factor in energy consumption, water usage, programme duration and maintenance requirements.

Key buying criteria compared

Compatibility and dimensions

Before placing your order, note down the exact model name and compare it with the product details. For a screen protector, the thickness, coverage and case compatibility are all relevant, as well as the smartphone model. For example, the Hama Clear Protect for iPhone 17 Pro and iPhone 18 Pro is described as 0.33 mm thick, with 9H hardness, electrostatic adhesion and an EcoFrame installation aid. According to the product details, these specifications apply to the models listed and shouldn’t be assumed to apply to other iPhones.

For large appliances, height, width, depth and weight are essential. Measure the route into your home, doorways, available floor space and connections. According to the product details, a Bosch heat pump tumble dryer with a 9 kg capacity measures 59,8 × 84,2 × 61,3 cm. A washer-dryer also requires suitable water connections, provision for exhaust air or condensate, and a floor that can support its weight.

Choose a capacity that suits your household

The stated capacity doesn’t always represent the amount that can be dried or processed on every programme. A washer-dryer, for example, may have a higher washing capacity than drying capacity. The Samsung model is listed as 9 kg for washing and 6 kg for drying. The AEG LWR9W81609 has a capacity of 10 kg for washing and 6 kg for drying.

For individuals, a large appliance may mean longer cycle times and take up unnecessary space. Families, on the other hand, often benefit from a larger drum capacity. For an electric breast pump, other factors matter: flange sizes, operating modes, intensity settings, cleaning and guidance for individual users are more important than motor power alone.

Energy, noise and what’s included

For washing machines, the EU energy efficiency scale runs from A to G. Compare energy consumption per 100 cycles and water consumption per cycle. For washer-dryers, consider the washing cycle and combined wash-and-dry cycle separately. According to the product details, the Bosch heat pump tumble dryer has an energy efficiency rating of B, a noise level of 59 dB and a rated capacity of 9 kg.

For a gaming monitor, refresh rate, resolution, panel type, connections and adaptive sync are the key considerations. A 24-inch model with a 144 Hz refresh rate and Full HD resolution may be suitable for PC gaming, provided your computer can output the required frame rate. Also check that the HDMI and DisplayPort connections are compatible with your existing device.

FAQs about buying electronics and household appliances online

What should I check before buying a washing machine online?

Compare the energy rating, consumption per 100 cycles, water consumption, capacity, spin speed, noise level and dimensions. You should also check the connection type, door hinge, what’s included and installation requirements.

How long does an electric toothbrush last?

Its lifespan depends on the battery, charging habits, care and availability of replacement parts. Brush heads are usually replaced regularly; the Oral-B models mentioned are listed as needing a new brush head about every three months. For the lifespan of the toothbrush handle, check the manufacturer’s guidance and warranty terms.

Is a Wi-Fi-enabled household appliance worth it?

Wi-Fi can be useful if you want to control start times, check status updates or select programmes remotely. Before buying, check whether the app is compatible with your smartphone, which features remain available without the app and whether a permanent internet connection is required.
