Choosing car accessories: practical buying tips for safety, comfort and roadside emergencies

When you look for car accessories, you’ll quickly come across plenty of products with impressive claims. But not every accessory is right for every car or driving style. A Bluetooth FM transmitter, for example, can be useful in an older car, while a wireless CarPlay adapter only works if your built-in system is compatible.

For drivers in the Netherlands, three common pitfalls are worth watching out for: compatibility issues, unclear technical specifications and accessories that prove awkward or unsafe to use while driving. Use the checks below to make a more informed choice.

Common pitfalls when choosing car accessories

1. A universal product isn’t always universal

A car phone holder may be described as suitable for a wide range of smartphones, but whether it fits depends on your dashboard, phone case and the space available. A car cup holder won’t necessarily fit every centre console either. So check:

  • the dimensions of your phone, cup or socket;
  • the shape of your dashboard or original cup holder;
  • the thickness of your phone case;
  • the space available around airbags and controls.

2. A big number doesn’t tell the whole story

A high peak current may sound appealing when choosing a car jump starter. But you should also check the compatible battery voltage, engine size, connection method, charge level and safety features. A car emergency starter that isn’t sufficiently charged won’t help if you break down on the way.

For a tyre pressure monitoring system, the measurement range, sensor batteries and fitting method are just as important as the display. Also check that the readings are suitable for the tyre pressures recommended by your vehicle manufacturer.

3. Extra features can make a device harder to use

A Bluetooth FM transmitter for your car with USB, USB-C and card reader ports can support several devices, but you’ll also need a clear FM frequency. A wireless CarPlay adapter only works if your car already supports wired CarPlay; this accessory typically adds wireless connectivity rather than replacing your entire infotainment system.

Always adjust settings while the car is stationary. This applies to FM frequencies, phone holders, mirrors and TPMS sensors.

Important specifications to check in advance

Compatibility and connection

For car electronics, check the power supply first. According to the product information, the Oxerbog FM transmitter is suitable for vehicles with 12–24 volt power and works via the 12V socket. It supports Bluetooth, USB sticks and Micro SD cards up to 32 GB. The stated FM band runs from 87,5 to 108,0 MHz.

If your car already has an infotainment system with CarPlay, check the requirements for an adapter. The Baseus SafeJourney Series Wireless CarPlay Adapter is designed for wireless CarPlay connectivity. Before buying, check that your car supports wired CarPlay and that its USB port transfers data rather than supplying power only.

Measurement range and accuracy

When choosing a tyre pressure monitoring system, check:

  • pressure range in bar or psi;
  • temperature range;
  • number of sensors;
  • battery type and expected life;
  • low- or high-pressure alerts;
  • suitability for a car, SUV, caravan, trailer or lorry.

The Tymate system specifies a range of 0–8 bar, or 0–116 psi, and four external sensors. According to the product information, it also measures tyre temperature and provides alerts for issues including rapid leaks, abnormal pressure and high temperatures. The stated accuracy deviation is less than 2 psi. This is a product specification, not a substitute for checking with a suitable tyre pressure gauge.

Fitting, materials and maintenance

A blind-spot mirror should not obstruct the main view in your original mirror. Convex mirrors can make distances look different, so use them only as an additional aid and always check carefully for yourself when changing lanes.

For a magnetic phone holder, check whether your phone uses MagSafe or a magnetic ring supplied with the holder. For a car cup holder, check the diameter and shape of the original recess. The product information for the 2-in-1 model mentions an adjustable opening and a base for round cup holders, but not square or irregular openings.

Frequently asked questions about car accessories

Which car accessories are useful for everyday driving?

For your daily commute, a car phone holder, a suitable Bluetooth solution and a compact emergency starter are often useful. First, check which connections your car already has. A car with wired CarPlay may benefit from a wireless adapter, while an older audio system may be better suited to an FM transmitter.

How long does a car jump starter last?

Its lifespan depends on storage temperature, charge level and use. Follow the instructions and recharge the device periodically, even when you’re not using it. For the BuTure Beta08, the product information recommends charging it every three months to keep the battery ready for use.

What does a tyre pressure monitoring system cost to run?

As well as the purchase price, you’ll need to allow for replacement sensor batteries and possibly new seals. The Tymate system uses CR1632 batteries, with an estimated life of around two years. Check the sensors regularly and compare the displayed readings with the tyre pressures recommended for your vehicle.
