How to Buy the Best OBD2 Bluetooth Adapter

How to Buy the Best OBD2 Bluetooth Adapter

1. Compatibility

First, you must ensure the OBD2 adapter you pick is compatible with your vehicle. You may need to refer to your vehicle's user manual to ascertain compatibility with this adapter.

The law in many places requires that any vehicle made after 1996 must have the OBD system. Hence, most modern OBD2 Bluetooth adapters are designed to work with all cars made after 1996. Therefore, almost any adapter should work for you provided you do not have an older car.

Besides compatibility with your vehicle's OBD system, the adapter you choose needs to be compatible with your phone. Here you need to check whether the unit works with Android, iOS, or windows. But, something that can work with all 3, like the Veepeak OBDCheck 8542040086, is always a better buy.

2. Specific or Third-Party Apps

Specific App

These apps are typically designed exclusively for a particular OBD2 adapter. In most cases, they are from the adapter manufacturer and do not work with OBD2 adapters from different brands.

The main advantage of a specific app is that it is very accurate since it has been designed to work with the particular OBD2 adapter. However, it does not have as many features as a third-party app.

Third-party app

A third-party OBD2 app is usually made for commercial reasons and can work with a wide range of OBD2 adapters.

Also, these apps are straightforward to install and have more advanced features. But, while the third-party app has many features, it tends to be less accurate than the specific app.

3. Ease of Use

One of the biggest reasons people choose the OBD2 Bluetooth adapter over the regular OBD2 scanner is ease-of-use.

Indeed, all you have to do is connect the OBD2 adapter to your vehicle's OBD diagnostic port, download the app, and pair it with the adapter.

However, some can be a little more complicated, meaning you need to check the instructions and other things like user reviews to determine the ease of use before buying.

4. Price

The OBD2 Bluetooth adapters are smaller and simpler devices that deliver the same function as a dedicated OBD scanner. Also, they come in a more affordable price tag.

However, the prices vary from one model to the other, depending on the features and functionalities. A professional-grade and feature-rich OBD2 adapter will cost more than a basic one.

That said, some highly affordable ones like the Veepeak VP11 still do a fantastic job despite the smaller price tag.

5. Warranty

Like any other product, a warranty is what gives you assurance the OBD2 Bluetooth adapter will last. Therefore, as you shop for one, always go for something with a warranty.

The warranty period also matters, and the longer it is, the better as you get extended protection. That said, with most of these products, you can expect to get anything from 1 to 5-year warranty.

Conclusion

The OBD2 Bluetooth adapter is very handy when it comes to vehicle diagnostics as it allows you to do everything from your smartphone. With our review above, finding the best OBD2 Bluetooth adapter should be a breeze.

From our list of products, the highly reliable and consistent BAFX Products 3127 takes the top overall spot as it also has broad vehicle compatibility and real-time monitoring.

But, for those looking for something that offers the best value for money, go with the BlueDriver LSB2
