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

A useful addition to your car may seem like an easy purchase. Yet many car accessories only reveal their drawbacks in everyday use. For example, a screen only makes a difference if your smartphone and audio connection are compatible. A dash cam can overwrite stored footage when loop recording is configured incorrectly. And an excessively long cable creates unnecessary loops at home and puts extra strain on the connections.

The most common pitfalls:

  • Looking only at resolution: a specification such as 4K or 1080p does not tell you everything about connections, viewing angle, storage or image delay.
  • Overlooking compatibility: wireless Apple CarPlay does not automatically work with every iPhone or every car. Some systems require a vehicle with factory-fitted wired CarPlay.
  • Choosing the wrong length or power connection: a 3-metre HDMI cable is practical for a TV and media player, but it is not always necessary when devices are positioned next to each other. A car accessory must also be suitable for a 12V or 24V power supply and be securely mounted.

Which specifications should you check?

1. Compatibility with your car, phone and connection

When choosing a portable CarPlay screen, first check:

  1. Does it work with Apple CarPlay, Android Auto or both?
  2. Is the connection wireless or via USB?
  3. Does the car support a 12V or 24V connection?
  4. How is audio sent to the car’s speakers: via Bluetooth, AUX, FM or a built-in speaker?

The ESSGOO solution states that it supports wireless Apple CarPlay and Android Auto, iOS 10+, Android 11+ and a wide 12–24V power range. According to the product description, this makes the system suitable for various cars, SUVs, vans and lorries with a standard cigarette lighter socket. However, check that the installation does not obstruct your view.

Compatibility is more specific with a baby camera for use in the car. According to OTTOCAST Cabin Care’s product description, a vehicle with original wired CarPlay and a touchscreen is required. The CarPlay function is intended for iPhone; according to the description, Android users can only use the camera functions.

2. Image quality, viewing angle and storage

A dash cam for your car needs more than a high resolution. Also consider:

  • Front and rear cameras: a reversing camera can help when manoeuvring, but the installation and cabling also affect ease of use.
  • Viewing angle: a wide-angle lens captures more of your surroundings, but may cause greater distortion around the edges.
  • Storage: check whether a memory card is included and what maximum capacity is supported.
  • Loop recording: this automatically overwrites older footage. Important recordings should therefore be locked or saved manually.

The ESSGOO 10.26-inch set lists a 4K front camera, a 1080p rear camera, two 140-degree viewing angles and an included 64GB TF card. According to the product description, the system supports cards up to 128GB. These are verifiable product specifications; they do not guarantee that footage will be usable in every traffic situation.

3. Cable standard and length

If you are combining car accessories with home entertainment, you may also be looking for an HDMI cable, a 3-metre HDMI cable or a 1080p HDMI cable. In that case, check:

  • the number of HDMI connections and whether both plugs are male;
  • the distance between the source device and the screen;
  • the supported HDMI specification;
  • resolution and refresh rate;
  • how the cable will be routed.

According to the product descriptions, the Neomounts cables mentioned comply with HDMI 1.4 and support up to 1080p+ at a maximum of 120 Hz, bandwidth of up to 10.2 Gbps and image resolutions up to 1440p. This makes them suitable for many Blu-ray players, televisions and receivers. They are not automatically the right choice for applications requiring a higher HDMI version.

A 3-metre cable gives you room to move without immediately needing an especially long cable. For a larger living room, 5 or 7.5 metres may be more practical. Do not bend a long cable sharply, and never pull on the cord to disconnect the plug.

Choosing an HDMI cable for home use

For a direct connection between, for example, a Blu-ray player and television, Neomounts HDMI cables are a practical option. The models feature two male HDMI connectors and use HDMI 1.4.

  • 1 metre: suitable when devices are positioned close together.
  • 1.8 metres: provides a little extra room behind a TV unit.
  • 3 metres: useful when the source device is on a cabinet or next to the television.
  • 5 metres or 7.5 metres: suitable for greater distances, but route the cable carefully and avoid sharp bends.

A cable does not become faster simply because it is thicker or more expensive. Above all, check that the specifications of the cable and devices are compatible. According to the product description, the 3-metre version supports 1080p+ up to 120 Hz and 10.2 Gbps. The 1- and 1.8-metre models state a statutory minimum guarantee of two years under EU consumer law; the 5- and 7.5-metre versions are listed with a five-year guarantee.

Frequently asked questions about car accessories

Which car accessories are useful for everyday use?

That depends on your vehicle and driving habits. A digital tyre inflator is practical for regular checks. A portable CarPlay screen can add navigation and hands-free control to a car without a modern infotainment system. Before buying, check the power supply, mounting method and smartphone compatibility.

Does wireless Apple CarPlay work in every car?

No. Some screens work independently via a 12V connection, while other accessories require a vehicle with original wired CarPlay and a touchscreen. Therefore, read the compatibility requirements and also check whether Android Auto is supported.

How long should an HDMI cable be?

Measure the distance between the HDMI devices and add a little extra for bends. Do not choose an unnecessarily long cable if the devices are next to each other. For a TV unit, a 3-metre HDMI cable is often practical; for a greater distance, 5 or 7.5 metres may be needed. For every length, check the supported HDMI specification, resolution and refresh rate.
