Choosing car accessories: practical solutions for storage, driving and maintenance

A car can quickly become cluttered. Shopping rolls around in the boot, cables disappear under the seat and a drinks bottle just won’t fit in the existing holder. With the right car accessories, you can make the interior more practical – but an appealing product description doesn’t always tell you enough about how well it will work in your vehicle.

Pay particular attention to these common pitfalls:

  • Universal doesn’t always mean it fits. A car cup holder or phone mount may only be suitable for certain round cupholders, air vents or dashboard shapes.
  • Capacity is given without context. A 60-litre boot organiser sounds spacious, but it also measures 50.8 × 36.8 × 32 centimetres. So measure your available space first.
  • Extra features can have drawbacks. A magnetic sunglasses holder for the car is handy, but it shouldn’t be used for cards with a chip or magnetic stripe. A Bluetooth FM transmitter also needs to be set to a free FM frequency.

Which specifications should you check?

1. Dimensions and fitting

Before you buy, measure the spot where the accessory will go. For a car organiser, check the width of the rear seat or boot. For a phone mount, it’s all about the type of fixing: magnet, air vent, dashboard or windscreen.

An accessory must not block your view, the controls or an airbag zone. Only fit and adjust products when the car is stationary.

2. Material and weight capacity

Look beyond words like “sturdy”. Check the material and the actual construction. A car storage box made of 600D Oxford fabric has different properties to a thin fabric bag. Reinforced sides, a base plate and adjustable straps help keep the box upright.

For a car cup holder, the maximum size matters. One model from the product description has an adjustable opening of around 6.6 to 9.9 centimetres; another model is designed for cups up to roughly 9.5 centimetres and features EVA non-slip material. That difference determines whether your thermos will fit.

3. Connection, range and vehicle compatibility

A Bluetooth FM transmitter works via the 12V socket and uses an FM channel to send sound to your car radio. So check:

  • compatibility with your phone and operating system;
  • available USB and USB-C ports;
  • supported music formats or storage media;
  • the voltage range of your car;
  • possible interference from an occupied FM frequency.

The Oxerbog transmitter in this selection is, according to the product description, suitable for vehicles with 12–24 V, has two USB ports and a USB-C port, and supports USB sticks and MicroSD cards up to 32 GB. According to the brand description, automatic Bluetooth reconnection and voice assistant support are also included. These features depend on correct installation, phone settings and your car radio.

Other handy car accessories

A collapsible car bucket is practical for washing, camping or fishing. The model mentioned has a 20-litre capacity and PVC walls. Do not fill it with boiling water, strong chemicals or sharp objects.

For bikes, a bike storage solution outside the car is relevant. The tent described has a galvanised steel frame, a PE cover and space for several bikes or electric scooters. Place such a tent on a level surface and anchor it in windy conditions.

A sunglasses holder for the car on the sun visor saves space. The magnetic models in this selection are, according to the product description, intended for glasses, tickets and non-magnetic cards. Do not store bank cards, parking tickets or access passes with a chip or magnetic stripe in them.

Frequently asked questions about car accessories

Which car accessories are useful for everyday use?
