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

A car accessory should solve a specific problem. Perhaps your phone keeps slipping while you’re using navigation, there’s sand on the floor mat, loose shopping in the boot or a flat battery after the car has been parked for a long time. Yet many product pages are packed mainly with bold promises. This can make a cheap purchase seem appealing, even though the accessory may not fit properly or could be awkward to use in practice.

The most common pitfalls when choosing car accessories are:

  1. Not checking dimensions and compatibility
    A cup holder will not always fit into a round console. A phone holder may not be suitable for a thick phone case. A wireless CarPlay adapter will also only work if the car already supports wired CarPlay or Android Auto.

  2. Marketing claims without context
    Stated suction power, charging capacity or maximum airflow mean little without information about operating time, connection type, battery type and maintenance. Always check the complete product specifications.

  3. Choosing the wrong installation position
    An accessory must not block your view, controls or an airbag zone. Only install a display, blind-spot car mirror or phone holder in a position that remains safe while driving.

Which specifications deserve attention?

1. Compatibility and dimensions

Check the following before buying:

  • the dimensions of the accessory;
  • the size of your smartphone, including its case;
  • the connection type: USB, USB-C, 12V or 220V;
  • the available space on the dashboard, air vent or centre console;
  • the supported software and vehicle systems.

With a phone holder for the car, magnetic strength is not the only important factor. Check whether your phone supports MagSafe or requires a metal ring sticker. A holder for a motorbike or bicycle must fit the diameter of the handlebars and accommodate the thickness of the phone with its case.

For a wireless CarPlay adapter or Android Auto adapter, check whether the car originally supports wired projection. An adapter will generally not create a completely new multimedia system in a car that does not already have this basic function.

2. Power supply, battery and operating time

Accessories that require power need a suitable connection. A mini fridge for the car often runs on 12V, while some models also support 220V. Check how much space is available and whether the cool box remains connected to the battery when the car is stationary.

For a portable car vacuum cleaner, battery capacity, charging time, filter type and included nozzles are more important than a high power rating alone. For example, the EAFC handheld vacuum cleaner lists a 6000mAh battery, USB-C charging and a washable HEPA filter. According to the product description, the device is designed for vacuuming, blowing, inflating and vacuum sealing. Check that the battery is fully charged before use.

For a car battery charger, the charging voltage must match the battery. The EAFC model is a 12V charger for AGM, GEL, SLA, EFB and wet lead-acid batteries, among others, with a stated range of 4 to 100Ah. Connect the clamps first and only then connect the mains power, as stated in the product instructions.

3. Materials, attachment and maintenance

An accessory that is moved frequently benefits from sturdy connections and straightforward maintenance. Look out for:

  • ABS, aluminium or Oxford fabric in structural components;
  • non-slip feet or a locking mechanism;
  • a filter that can be removed and cleaned;
  • water resistance where relevant;
  • spare parts and warranty terms;
  • CE marking and other product information where applicable.

A car-washing brush may feel soft, but sand caught between the fibres can still cause scratches. Always rinse both the car and the brush thoroughly before washing. Voltage is particularly important for car lighting. According to the product information, the MAODANER strip operates at 10–16V and is intended for interior use. Check the connection and operating voltage before installation.

Other useful car accessories

For an organised family car, a car boot organiser is a practical choice. Look at the capacity, compartment layout, base support and fastening straps. According to the product details, the Oxerbog organiser has a capacity of 60 litres, three compartments and a foldable design.

An OBD2 diagnostic tool can be useful for DIY car owners who want to read fault codes. The Thinkcar ThinkDiag Mini works via Bluetooth with an app and supports multiple communication protocols. Always check whether your vehicle model is supported, and do not confuse reading fault codes with carrying out repairs.

For longer journeys or camping, a mini fridge for the car can be useful. Check the difference between thermoelectric and compressor cooling, as well as the capacity and power connection. A 6-litre Cecotec model lists a 12V power supply and a temperature setting ranging from 5°C to 65°C for cooling and heating.

Other options include a car cup holder, car cooling fan, electric impact wrench and car-washing brush. Always choose based on fit, connection type and how you will actually use the product.

Frequently asked questions about car accessories

Which car accessories are useful for daily commuting?

A phone holder, a suitable CarPlay or Android Auto solution and a cup holder are commonly used every day. Choose a mounting system that does not obstruct your view, and only operate accessories when the car is stationary.

How can I prevent a car accessory from not fitting?

Measure the installation area and compare it with the product specifications. For phone holders, also check the dimensions of the phone including its case. With a cup holder, the shape and diameter of the existing console opening are decisive.

Do electrical car accessories use a lot of power?

It depends on the product. A USB fan or small LED set will generally use a different amount of power from a mini fridge or battery charger. Check the voltage, wattage and operating time. Disconnect accessories when they are not needed, especially if they use a connection that remains active while the car is stationary.
