The right gadget can make everyday driving safer, cheaper and a good deal more comfortable, which is why UK drivers are spending more than ever on car accessories. Whether you have just picked up your first car or you are trying to get more out of the one you already own, a handful of well chosen bits of kit can genuinely change how your car feels to live with.

‍

In this guide we run through the most popular car gadgets in the UK right now. Most are affordable, widely available and quick to fit yourself, and they cover the three things drivers care about most: safety, convenience and keeping running costs down. Here is what is worth your money in 2026.

‍

1. Dash Cams

‍

Dash cams remain one of the most popular gadgets in any car, and for good reason. In the event of an accident, clear front and rear footage can settle a dispute quickly, protect you against fraudulent or exaggerated claims, and help if you are hit by an uninsured driver. Many UK insurers now offer a discount if you fit one, so a dash cam can partly pay for itself over time.

‍

Popular models range from the plug and play Garmin Mini 3 to feature packed options like the Nextbase 622GW and the Viofo A139 Pro, with prices spanning roughly £50 to £250 depending on resolution, parking mode and whether you want a rear camera included. Parking mode is a particularly useful feature, as it keeps recording while the car is parked and can catch anyone who bumps your car and drives off.

‍

2. Wireless CarPlay and Android Auto Adapters

‍

Plenty of cars support Apple CarPlay and Android Auto, but only through a wired connection, which means plugging your phone in every single journey. A wireless adapter, such as an AAWireless dongle or an Ottocast unit, converts that wired connection into a wireless one. You pair your phone once, then it connects automatically whenever you get in.

‍

These adapters have become hugely popular because they are cheap, usually between £40 and £90, and they solve a small daily annoyance without any permanent modification to the car. They also reduce wear on your charging port and cable, which tend to loosen over time from repeated plugging and unplugging.

‍

3. Phone Mounts and Holders

‍

A good phone mount is one of the cheapest upgrades you can make and one of the most useful. It keeps your phone in easy view for navigation and music while keeping your hands on the wheel. This matters legally as well as practically: using a handheld phone while driving in the UK carries a £200 fine and six penalty points, so a secure mount is the safe and lawful way to use your phone on the move.

‍

Magnetic MagSafe style mounts have become the go to option for iPhone users, while vent, dashboard and windscreen mounts remain popular for wider compatibility. Some now include wireless charging built in, so your phone tops up while it navigates.

‍

4. Portable Jump Starters and Battery Packs

‍

A flat battery is one of the most common reasons a car will not start, especially in winter, and a portable jump starter means you do not need to flag down another driver or wait for recovery. Modern lithium units, such as the NOCO Boost range, are small enough to keep in the glovebox yet powerful enough to start most petrol and many diesel engines several times on a single charge.

‍

Most double up as a USB power bank for charging phones and other devices, and some include a built in torch, which makes them a genuinely useful thing to carry year round. Prices typically start around £60 for a capable unit.

‍

5. Tyre Pressure Monitors and Portable Inflators

‍

Correctly inflated tyres are safer, last longer and improve fuel economy, yet checking them is easy to forget. Aftermarket tyre pressure monitoring systems (TPMS) use small sensors on each valve and a display that warns you in real time if a tyre is losing pressure, giving you early notice of a slow puncture before it becomes a problem.

‍

Alongside these, cordless portable tyre inflators have become very popular. Compact units from brands like Ring, Michelin and Xiaomi let you top up your tyres on the driveway or at the roadside without hunting for a working forecourt machine. Keeping your tyres at the manufacturer recommended pressure can noticeably improve your miles per gallon, so this is a gadget that pays back at the pump.

6. OBD2 Diagnostic Scanners

‍

Almost every car built since the early 2000s has an OBD2 port, usually tucked under the dashboard near the steering column. A small Bluetooth OBD2 scanner plugs into that port and pairs with an app on your phone, letting you read fault codes when a warning light appears. Instead of guessing what the check engine light means, you can see exactly which system has flagged an issue.

‍

This is especially popular with used car owners and anyone who likes to understand their vehicle. It can save money on garage diagnostic fees, help you decide whether a warning light is urgent or minor, and clear codes once a problem has been fixed. Popular options include the ELM327 based dongles and more polished apps such as those from Carly, with basic units costing very little.

‍

7. Fast USB-C Chargers and Multi-Port Adapters

‍

Many older cars have only a single 12V socket or a slow USB port that struggles to keep a modern phone charged, let alone a phone, a tablet and a dash cam at once. A multi-port car charger with USB-C Power Delivery solves this cheaply, delivering fast charging to several devices at the same time.

‍

Look for a charger that lists a decent total wattage and at least one USB-C PD port if you want fast top ups on the move. Compact GaN based chargers are a good choice, as they run cooler and deliver more power from a smaller unit. It is a small purchase, but on longer journeys it is one you will be glad you made.

‍

Final Thoughts

‍

You do not need to buy everything at once. If you are prioritising, start with the gadgets that keep you safe and lawful, a dash cam and a proper phone mount, then add the convenience and cost saving kit as you go. Most of the items above are affordable, easy to fit and available from the usual UK retailers, so you can build up your setup over time to suit how and where you drive.

‍

And if you are still choosing the car itself, Ayan offers FCA-regulated, Shariah-compliant  car finance to help you get on the road, so you can focus on enjoying the car and kitting it out exactly how you like.
