Choosing car accessories for the road: a practical guide to safe and comfortable journeys

Whether you’re taking a long drive to France, spending a weekend with a caravan or simply commuting every day, the right car accessories for the road can make all the difference. However, many products are harder to assess than the product photo might suggest. A cool box, for example, may work on 12V but not have enough space around the ventilation openings. A dog car seat belt may be adjustable but unsuitable for attaching to a collar.

The following pitfalls regularly cost motorists money:

  • Marketing terms without clear specifications: words such as “powerful”, “universal” or “safe” mean little without details of size, capacity, connections or materials.
  • The wrong power supply: an electric 12V cool box is not automatically suitable for prolonged use when the engine is not running. Also check whether a 230V adapter is included or available separately.
  • An unsuitable fit: a dog crate for the car, car seat cover or baby carrycot must physically fit. Measure your car and check the attachment points before ordering.

Which specifications should take priority?

1. Dimensions, capacity and attachment

Measure the available space between the seats, in the boot or on the back seat. Don’t just look at the external dimensions; consider the shape of the accessory too. A foldable pet crate measuring 102 × 69 × 69 cm may offer plenty of room to move around, but it will not be suitable for every back seat or boot.

Capacity is equally important when choosing a cool box:

  • 6 to 9 litres: suitable for drinks, snacks and a small lunch.
  • 22 litres: more practical for several people or a camping weekend.
  • 35 litres or more: useful for longer journeys, motorhomes and caravans, but requires more luggage space.

When choosing a car seat cover, check that it is compatible with the headrests, side airbags and seat belts. A cover must not interfere with the operation of any safety systems.

2. Cooling technology and energy consumption

A portable car cool box usually uses thermoelectric cooling or a compressor. Thermoelectric models are often compact and can heat as well as cool. The stated temperature will generally depend on the ambient temperature.

A compressor cool box is designed to operate across a wider temperature range and, according to the relevant brand’s product information, may also be used as a freezer. The BINGI 22L Portable Car Fridge Freezer, for example, states an adjustable range of -18 °C to 15 °C, with power supplied via 12V/24V DC and 100–240V AC. The EUHOMY 35L Compressor Cooler Box states -20 °C to 20 °C, two storage zones and app control.

For any car fridge, check:

  1. Whether a 12V or 24V connection is available.
  2. Whether battery protection is included.
  3. Whether there is at least approximately 10 cm of clear space around the ventilation openings.
  4. Whether the compressor needs to stand upright for a while after transport.
  5. Whether the stated noise level is acceptable for your intended use.

3. Materials, maintenance and safety details

When choosing a car jump starter, the maximum current, vehicle voltage and suitability for petrol or diesel engines are more important than the power bank’s capacity alone. According to the product description, the BuTure Beta08 is designed for 12V vehicles, with a stated peak current of 3000A, and is suitable for petrol engines up to 9.0 litres and diesel engines up to 8.5 litres. Only use a car emergency starter in accordance with the supplied instructions, and connect the clamps to the correct terminals.

For a dog car seat belt, the material and attachment method are crucial. According to the product information, the Oxerbog belt is made from nylon, has an adjustable length of 47 to 70 cm, reflective stitching and a swivelling metal buckle. The manufacturer recommends using it with a harness, not directly around the dog’s neck. This is an important distinction when comparing this type of accessory.

Frequently asked questions about car accessories for the road

Which car accessories are practical for a long drive?

That depends on the journey. An electric 12V cool box is useful for drinks and food. A car jump starter can provide emergency assistance if the battery is flat. For pets, a dog car seat belt or foldable pet crate are options worth comparing. Families with a baby should also check that a baby carrycot is suitable for the intended use and required attachment method.

Can a car fridge drain the battery?

This is possible if a cool box runs for a long time while the engine is switched off. It is therefore best to choose a model with battery protection and check the settings. With a compressor cool box, the selected cooling mode may also affect energy consumption. Follow the instructions and keep the ventilation openings clear.

How long does a car accessory last?

Its lifespan depends on the materials, use, storage and maintenance. Nylon straps should be checked for fraying and wear. A cool box should be cleaned dry and electrical components should be protected from water. Recharge a car emergency starter regularly, even when it has not been used. Before every journey, check the cables, buckles, zips and attachment points.
