Choosing car accessories without making a mistake: a practical guide to comfort and safety

A car doesn't have to be brand new to make driving more enjoyable, better organised or more modern. With the right car accessories, you can upgrade an older vehicle with smartphone connectivity, extra storage space or a more comfortable interior. However, accessories vary greatly in fit, installation and everyday use.

The main pitfalls to watch out for:

  • Universal doesn't always mean it fits. A universal car phone holder, for example, may not attach properly to every air vent. Likewise, a cup holder for the centre console will only fit if the shape and diameter match.
  • Lots of features don't always translate to real-world performance. A wireless CarPlay display may offer plenty of connection options, but always check the required iOS or Android version, power supply and audio options.
  • Safety is sometimes interpreted too loosely. A blind spot mirror for your car is only an aid and does not replace your regular mirrors or looking over your shoulder. What's more, car seat covers must not block any airbag openings.

What to look for when buying car accessories

1. Fit, dimensions and installation

Before you buy, measure the area where the accessory will go. For interior car accessories, pay attention to:

  • the diameter of an existing cup holder;
  • the width and shape of the air vents;
  • the available space around the dashboard;
  • the dimensions of a boot organiser;
  • whether the headrests are removable for car seat covers.

With a Tesla Model Y, a model-specific fit is more important than with a simple universal accessory. A sunshade for a panoramic sunroof must have the correct shape and fixing points. For older cars, also check whether a standard 12V socket is present.

2. Power supply and compatibility

Check the voltage before connecting any electrical product. According to the product description, the MAODANER car LED lighting operates on 10–16V and comes with a car charger. The lighting is designed for installation in the seams of the interior; test the product first before securing it in place.

A portable Android Auto screen or wireless CarPlay display does not work fully independently. Check:

  • whether your smartphone supports the required software version;
  • whether your car is compatible with 12V–24V;
  • how the sound reaches your car speakers: Bluetooth, AUX, FM transmitter or built-in speaker;
  • whether a reversing camera is included or sold separately.

The ESSGOO models differ in this respect. According to the product description, one version includes a front camera, rear camera and 64GB TF card. With the other version, a reversing camera must be purchased separately.

3. Material, fixing and maintenance

A sturdy housing is useful, but also check the fixing method. EVA pads can reduce vibration and contact noise in a cup holder, while adjustable straps help keep a boot organiser in place.

For fabric accessories, look for care information. According to the product description, an organiser made from 600D Oxford fabric is water-repellent and foldable, but prolonged exposure to direct sunlight can damage the material. Do not place sharp, flammable or exceptionally heavy items in a storage box.

For car accessories with lighting, neat cable routing is important. Cables must not obstruct your view, pedals, switches or airbags. Always fit or adjust accessories when the car is parked.

Frequently asked questions about car accessories

Which car accessories are useful for daily commuting?

A car phone holder, car cup holder and boot organiser are practical choices for everyday use. If you drive an older car, you might also consider an Android Auto screen or wireless CarPlay display. Check phone compatibility, power connection and how audio is played back beforehand.

How do I stop a car accessory from coming loose?

Clean the mounting surface, check the dimensions and follow the installation instructions. For a blind spot mirror, the surface must be free of grease and dust. Allow adhesive fixings to bond properly before driving. Never place accessories in front of airbags, your line of sight or important controls.

How much does it cost to use electrical car accessories?

Car LED lighting and displays typically draw power via the 12V socket or USB. The cost depends on the power consumption and usage time, but is usually minimal. However, make sure the connection does not remain active for long periods when the engine is off, to avoid draining the battery.
