How to choose car accessories without making the wrong purchase: a practical guide for every motorist

A phone holder that comes loose at the first bump, a steering wheel cover that starts to slip or a boot organiser that takes up more space than it creates: when it comes to car accessories, the difference often lies in the details. Product photos do not always show whether an accessory is suitable for your car, phone, steering wheel or everyday use.

Pay particular attention to these three common pitfalls:

• Universal does not automatically mean suitable. A dashboard mount can only stay securely in place on a smooth or suitable surface. A 37-39 cm steering wheel cover will not fit every steering wheel.
• An appealing feature means little without specifications. “Strong attachment” is only verifiable when details such as a suction cup, clamp, dimensions or load capacity are provided.
• Safety accessories require extra checks. A seat belt extender, dog car seat belt or car ramps must be suitable for the vehicle and the intended load. Do not use an accessory if the connection, dimensions or instructions are unclear.

Which specifications should you check?

1. Dimensions and compatibility

Before buying, measure the area where the accessory will be used. With a steering wheel cover, the diameter is decisive. The Dunlop PU cover is designed for steering wheels measuring 37-39 cm. This makes it suitable for many common models, but measuring is still advisable. A cover that is too loose can shift while steering, while one that is too tight can be difficult to fit.

With a dashboard mount, you should also check:

• Whether the dashboard is smooth, lightly textured or strongly curved.
• Whether the mount obstructs your view of the road, controls or air vents.
• Whether your phone, including its case, falls within the stated dimensions.
• Whether the attachment works with your phone. A magnetic phone holder may require a magnetic ring or adapter if your phone is not compatible.

2. Attachment and adjustability

A car phone holder must not only fit, but also stay securely in place. A suction cup generally works best on a clean, smooth surface. Clean the area first and press the suction cup firmly into place. A vent clip is compact, but it may affect the airflow or the vent slats.

The PAVAREAL CH78 uses a suction cup for the windscreen or a mirror attachment, has a telescopic range of 10-15 cm and can be rotated 360 degrees. This offers more positioning options than a fixed dashboard mount. Whatever type you use, adjust the angle before setting off and do not operate your phone while driving.

A magnetic mount is particularly convenient if you want to put your phone in place and remove it quickly. However, check that the magnetic disc is properly attached to the phone case. A thick metal case can reduce its effectiveness.

3. Load capacity, power and operating time

For a boot organiser, dimensions, attachment points and material are more important than simply the number of compartments. The Oxerbog storage bag measures 88 x 48 cm, has three adjustable straps and eight compartments, including four mesh pockets. Do not place sharp, flammable or heavy objects in a hanging bag, and make sure it does not obstruct your view.

When using car ramps, you must check that the load capacity is greater than the weight you actually intend to support. The stated set has a load capacity of up to 2.5 tonnes and a width of 330 mm. Also check the surface, wheel width and condition of the ramps before every use.

For an electric car charger, the following points are relevant:

• Type 2 connection: check that the car and charging cable use the same connection.
• Charging power: a 3.7 kW charger is suitable for a single-phase connection and will not charge at the same rate as a more powerful three-phase installation.
• Cable length: 7 metres is practical for a charging point close to the car; 10 metres provides greater reach but requires more space for tidy storage.
• Electrical installation: have a fixed connection and safety features assessed by a qualified installer. Do not use an extension lead as a permanent charging solution.

Choosing other car accessories with care

For families, a car headrest can provide additional support, but check its shape, dimensions and attachment to the seat. The Baseus ComfortRide measures 273 x 200 x 113 mm and weighs approximately 450 grams. Brand claims about cooling or comfort are not a guarantee for every user; focus primarily on fit and material.

A dog car seat belt should preferably be attached to a suitable harness, not directly to the collar. The Oxerbog version has an adjustable range of 47-70 cm, nylon construction and a zinc-alloy clip, according to the product information. Before setting off, check that the buckle actually fits your car’s seat belt socket.

If you are looking for a model car, RC drift car or remote-controlled toy car, pay attention to scale, age suitability, surface and battery. The Porsche 1:24 4WD drift car has two sets of tyres, LED lighting, USB charging and a stated play time of 20-40 minutes per charge. The product description states that it can be used indoors on tiled floors and outdoors on flat roads. When buying toys, take note of the recommended age and small parts.

Frequently asked questions about car accessories

Which car accessories are useful for everyday use?

A car phone holder, steering wheel cover and boot organiser are practical choices for many motorists. Choose based on measurable features such as the mounting method, dimensions, material and maintenance requirements. An accessory that does not fit offers little value, even at a low price.

How can I stop a dashboard mount from coming loose?

Remove grease and dust from the surface, attach the mount according to the instructions and check that the dashboard is suitable. With a suction cup, the surface must be smooth enough. A magnetic phone holder only works reliably when the magnetic attachment and phone case are compatible.

How much does it cost to charge an electric car at home?

The cost depends on the electricity tariff, charging losses, battery capacity and the number of kilowatt-hours you charge. Multiply the number of kilowatt-hours used by your tariff. The charging power of the electric car charger mainly determines how quickly you charge; it does not directly determine the price per kilowatt-hour.
