Choosing car accessories: a practical buying guide to safety, comfort and organisation

A new phone holder, dash cam or boot organiser may seem like an easy purchase. However, many car accessories aren’t suitable for every vehicle. A holder may come loose on a bumpy road, a wireless CarPlay adapter may only work if your car already supports wired CarPlay, and a car cover in the wrong size can cause more trouble than it’s worth.

The main pitfalls are usually:

  • Marketing claims without verifiable specifications: words such as “universal”, “waterproof” or “safe” don’t tell you much without measurements, connections and conditions of use.
  • Compatibility issues: when choosing in-car electronics, check the smartphone type, operating system, USB connection, vehicle model and existing media system.
  • Incorrect installation: an in-car accessory must not obstruct your view, airbags, controls or ventilation. Also check that it stays securely in place during everyday use.

Which specifications should you check?

1. Compatibility and dimensions

Before buying a car organiser, car cup holder or car phone holder, measure the available space. For example, a 2-in-1 cup holder may only fit properly in a round cup holder. Also check the diameter of your cups and bottles. For a phone holder, the shape of the air vent and the weight of your smartphone also matter.

For a car cover, length, width and height are more important than the description “universal fit”. The HELLO LEIBOO cover measures 5,4 × 1,75 × 1,2 metres and, according to the product information, is recommended for cars about 4,7 to 4,9 metres long. Roof bars, spoilers and wing mirrors can affect the fit.

2. Connections and system requirements

If you’re considering a wireless CarPlay adapter or Android Auto adapter, first check whether your car already supports wired CarPlay or Android Auto. An adapter won’t automatically add these features to every older radio system. Also check that your smartphone is compatible and see which USB adapter is included.

For a dash cam, the key considerations include resolution, storage, power supply and parking mode. The LNDU V100 lists 2K recording, Wi-Fi, a G-sensor, loop recording and parking mode with a hardwire kit. This means parking mode depends not only on the camera, but also on it being connected to the car correctly.

3. Safety, installation and maintenance

A blind-spot mirror is only an aid. The product information for the round convex mirrors states that the image may be slightly distorted and that you should still use your original wing mirror and look over your shoulder when changing lanes. Position accessories like these so they don’t obstruct your main view.

When choosing car lighting, check the voltage, heat output and cable routing. The MAODANER interior lighting lists an operating voltage of 12 volts, Bluetooth app control and a cuttable fibre-optic cable. Test the lights before installation and tuck the cables away neatly. Bright or moving lights must not distract the driver or obstruct the view outside.

Frequently asked questions about car accessories

Which car accessories are useful for the daily commute?

A car phone holder, dash cam, car FM transmitter or wireless CarPlay adapter can be useful. Choose one that works with the connections available in your car, and make sure it doesn’t obstruct your view or access to the controls. For loose items, a car organiser or small car bin is often simpler than using several separate containers.

How can I stop a car accessory from coming loose?

Clean the mounting surface, follow the instructions and check that the fixing is suitable for your car. For a blind-spot mirror, the adhesive needs to bond properly, and you should wait after installation before driving. With a boot organiser, non-slip material, dividers and straps can help prevent it from shifting.

Do in-car electronics and lighting use a lot of power?

It depends on the product and how it’s connected. Check the stated voltage, charging output and power supply. An accessory plugged into the 12V socket may continue to draw power when the vehicle is switched off. If the instructions say to do so, unplug an FM transmitter or similar device when you park.
