Car Accessories Worth Buying
Useful car accessories reduce a specific failure, delay, or distraction. Everything else needs to earn its space. This guide explains where common tools help, what to check before buying, and when the better answer is to wait.
Use the checklist in order, then make a clear Buy, Wait, or Skip call.
Dashcams: evidence, not entertainment
A dashcam can be practical for drivers who want a record of an incident, but setup, heat tolerance, storage, and local laws affect the value.
- Buy if you drive frequently, park in public areas, or want a clearer record after a road incident.
- Check how footage is saved, whether the camera loops reliably, and how easy it is to retrieve a file without removing the unit.
- Confirm the mounting position does not block your view or interfere with vehicle sensors, airbags, or inspection requirements.
- Wait if you are not prepared to manage storage cards, installation, and privacy considerations for passengers or shared vehicles.
Tire inflators: a small tool for a common delay
A portable inflator is useful when you check tire pressure and need to correct a slow loss before it becomes a roadside problem. It is not a substitute for repairing a leak.
- Buy if your vehicle’s recommended tire pressures are easy to access and you will actually check them periodically.
- Compare power source, hose reach, pressure display, duty cycle, and whether it fits the tires you own.
- Keep a separate pressure gauge if you want a second reading rather than relying on one device alone.
- Skip it as a reason to keep driving on a visibly damaged, repeatedly deflating, or overheating tire.
OBD readers: useful when you know the limit
An OBD reader can surface diagnostic codes and basic vehicle data on compatible vehicles. A code points to a system to investigate; it is not an automatic repair plan.
- Buy if you want to document a warning light before scheduling service or compare the code with a repair professional’s explanation.
- Check compatibility with your vehicle, phone, operating system, and the app’s ongoing access or subscription terms.
- Record the code and conditions before clearing anything; clearing a light can erase helpful context without solving the cause.
- Wait if you are using the tool to avoid inspection for a safety warning, drivability issue, or repeated alert.
Jump starters, phone mounts, and emergency kits
These tools serve different jobs. Buy the one that covers a realistic failure point in your driving pattern, then learn how to use it before the emergency.
- Consider a jump starter if you keep the unit charged, understand its safety instructions, and drive in places where help may not be immediate.
- Choose a phone mount only if it attaches securely, does not block controls or visibility, and lets you set navigation before moving.
- Build an emergency kit around your climate and trips: visibility items, basic first aid, water, light, warm layers, and a way to communicate can matter more than novelty tools.
- Review all battery-powered gear periodically; an uncharged jump starter or expired kit is stored clutter, not preparedness.
Decision checkpoint
Buy, wait, or skip.
Buy if
The accessory reduces a realistic risk or recurring inconvenience for your vehicle, route, and driving habits—and you will maintain it.
Wait if
You have not confirmed fit, compatibility, installation requirements, or whether the tool solves the actual problem.
Skip if
The item exists mainly as a gadget, asks you to bypass safety guidance, or creates a distraction while driving.

Common questions
Before you go.
Which car accessory should I buy first?
Start with the gap most likely to affect your own driving: tire-pressure management, safe phone navigation, documented incident evidence, or basic preparedness. There is no universal first accessory for every driver.
Are OBD readers worth buying?
They can be worthwhile for compatible vehicles when you use them to understand and document diagnostic information. They are not a replacement for professional diagnosis of safety, drivability, or recurring issues.
Is a portable jump starter better than jumper cables?
They solve different constraints. A jump starter can help when another vehicle is unavailable; cables can be useful if you know the safe connection procedure and have access to a compatible vehicle. Consider your actual travel conditions.
