Choosing car accessories without costly mistakes: a practical guide for every journey

Choosing a new car accessory often seems straightforward. Yet problems usually only become apparent after purchase: a screen does not work with your phone, a dashcam lacks a suitable memory card, a battery charger is incompatible with the battery, or a charging cable turns out to be too short for the drive.

With this guide, you can compare car accessories based on useful specifications rather than vague marketing terms. The focus is on compatibility, installation, safety and everyday use in the Netherlands.

Common pitfalls when buying car accessories

1. “Universal” does not always mean a perfect fit

A device may be suitable for many vehicles but still require specific connections or conditions. For example, a portable CarPlay screen usually works via a 12V socket, while an integrated adapter may require an existing wired CarPlay function.

So check the following in advance:

  • The vehicle’s voltage, such as 12V or 12–24V.
  • The connection: USB, USB-C, AUX, FM transmitter, Bluetooth or Type 2.
  • The iOS or Android version.
  • Whether a reversing camera, hardwire kit or memory card is required separately.
  • The available space on the dashboard and the length of the cables.

2. High resolution is not everything

Resolution is important for a dashcam for your car, but the lens, field of view, storage and recording functions also matter. A 4K camera offers little practical benefit if footage is not automatically protected after a collision or if the memory card fills up quickly.

Look out for features such as loop recording, a G-sensor, night mode and parking monitoring. For 24-hour recording, also check whether a suitable hardwire kit is required. This helps prevent the camera from putting unnecessary strain on the vehicle battery.

3. A powerful battery solution requires the right battery type

A car battery charger must be compatible with the battery technology. This may be lead-acid, AGM, EFB, GEL or a lithium battery. Smart charging is useful, but it does not replace checking the vehicle or battery manual.

With a car jump starter, peak current, engine capacity, cable quality and reverse-polarity protection are important considerations. Do not use a jump starter with a damaged, leaking or frozen battery.

The most important specifications to compare

Screens, CarPlay and Android Auto

A wireless Apple CarPlay connection is convenient when you do not want to connect a cable every time. Android phones require Android Auto support. Some systems support both, while others are limited to iPhones or only work with a factory display featuring wired CarPlay.

An Android Auto screen or portable CarPlay screen must also offer a suitable audio method. Check whether you can play sound via:

  • Bluetooth;
  • AUX;
  • FM transmitter;
  • the built-in speaker

A large screen is not automatically more comfortable if it obstructs your view. Position the device low enough and secure it firmly to the dashboard or windscreen.

Cameras and storage

For a reversing camera, resolution, water resistance, viewing angle and cable routing are more important than the pixel count alone. A camera mounted outside the vehicle must be suitable for moisture and changes in temperature. Also check whether the camera is supplied with the product or must be purchased separately.

For a dashcam, recording capacity and file protection are practical points to consider. A supplied TF card can simplify installation, but always check the maximum supported storage capacity.

Charging and vehicle batteries

An EV charger Type 2 uses the IEC 62196-2 connection, which is common in Europe and suitable for many electric cars and plug-in hybrids. Also check:

  • The car’s maximum charging capacity.
  • Single-phase or three-phase support.
  • Adjustable current.
  • Cable length and installation location.
  • Protection and installation requirements according to the manual.

A 7 kW charger cannot automatically be used at that speed in every home or car. Have a fixed wallbox installed in accordance with the applicable installation regulations.

Other car accessories worth comparing

Not every accessory belongs on the dashboard. For roadside emergencies, a car battery charger or jump starter can be useful. For motorcyclists, a waterproof motorcycle CarPlay screen, Bluetooth and a sturdy mount are more important than a large display. With a reversing camera, always check the connection and installation instructions.

Accessories for use around the car may also suit your needs:

  • An EV charger Type 2 for charging at home.
  • A digital meat thermometer for barbecuing during a camping trip.
  • A mini projector for entertainment on holiday or during a stop.
  • A dashcam for your car with a Wi-Fi app when you want to view footage quickly.

Frequently asked questions about car accessories

Can I use a portable CarPlay screen in any car?

Not automatically. Check whether the car has a suitable 12V or USB connection and how the sound is transmitted. For wireless Apple CarPlay, both the phone and the system must support this function. Some adapters also require existing wired CarPlay.

How long will a car battery last with accessories connected?

This depends on the power consumption, the condition of the battery and how long the accessories are used. A dashcam with parking mode may draw extra power, particularly when it is connected permanently. For fixed installation, use a suitable hardwire kit and follow the manufacturer’s instructions.

What does it cost to use an EV charger Type 2?

Charging costs depend mainly on the electricity tariff, the amount of energy charged and the car’s efficiency. Multiply the number of kilowatt-hours charged by your tariff. The charger’s maximum power does not automatically determine how much power the car actually draws.
