LAUNCH X431 PROS Mini vs Diagun V – H2H comparison and review

The Launch X431 Pros Mini and the Diagun V are some of the advanced OBD2 scanners on the market. 

Here I will compare the two, from price to hardware, features, and more. 

Before I start comparing the two, I know that some of you come here for a Diagun IV review. If so, you should note that the Launch Diagun IV has been replaced by the Diagun V that offers a better user experience for a similar price.

Let’s get started!

Price and lifespan

The Launch X431 Pros Mini is a relatively expensive item and can cost $70 to $80 more than the Diagun V.

Both the OBD2 scanners offer a 5-year warranty. However, from personal experience, I can easily say that these products are well built and will last a very long time. Investing in any of these will help you save a lot of money down the road.

Besides the warranty, both devices come with two years of free updates. It is a step up over the 1-year free update that comes with many basic OBD2 scanners.

PROS Mini VS Diagun V – Hardware comparison

Although both these advanced code readers offer similar functionalities, where they differ is the hardware. For some, this might be a deal-breaker. In the table below, you can see the hardware differences between the two products.

The X431 Pros Mini offers a larger screen than the Diagun V. It provides a much comfortable viewing experience. However, the latter has a higher resolution which many may prefer. As a mechanic, the screen resolution does not really matter as long as I can read. At the end of the day, your eyes won’t be able to distinguish the difference between 720*1280 and 1024*600 pixels.

Besides a larger screen, The X431 Pros Mini also offers more computing power with a higher 1.3 GHz Quad-core CPU and 2 GB RAM. Although the difference in CPU power might be insignificant for many, a larger RAM is highly desirable since it makes the device much faster.

Both the devices offer similar storage capacities of 32 GB and do not come with an expandable SD memory slot. Having no slots for expandable memory is not an issue with scan tools as you do not need much storage in the first place.

The two OBD2 scanners feature a lithium polymer battery rather than a lithium-ion. Although lithium-ion provides high power density (and it’s cheaper), lithium polymer is perfect for such devices as it offers flexibility, faster charging, and is lightweight.

The Diagun V comes with a 2,500 mAh battery. On the other hand, the Pros Mini rocks a substantially bigger 4,680 mAh battery. Whether you’re a mechanic or a DIY enthusiast, having a larger battery pack means you’re not going to run out of juice anytime soon. 

The two devices also feature a 5-megapixel rear camera allowing users to take pictures of their vehicle or components. They can then share it with their friends or with the online community for troubleshooting purposes.

They have the same functions!

Both the devices have similar functions so let’s look into a bit more detail on what these devices are capable of.

10 basic modes

Just like any other OBD2 scanner, these also come with 10 basic modes and include the following:

• O2 sensor test
• On-board monitor test
• Component test
• EVAP
• Vehicle information
• And more

ECU coding

These devices help users reprogram certain aspects of a vehicle, unfold hidden features, and remove the annoying functions of a car through coding. 

Special functions

The two advanced code readers offer more than 31 special functions, and these include:

• Oil reset
• Steering angle calibration
• Electronic parking brake reset
• Tire pressure monitor system reset
• Battery maintenance
• Key coding
• DPF regeneration
• And many more

With so many special functions available, these two scanners are ready to meet your daily needs as a mechanic and solve 99% of car diagnosis problems.

Remote diagnosis

This is a cool feature available on both devices, helping these professionals get the repair job done faster than before. 

Now car owners can simply connect with mechanics using their application and also give them remote access to their OBD2 scanner. Mechanics can view data, access test reports, and other features to help them diagnose the vehicle. This saves a lot of time and effort on both sides.

All modules diagnosis in 10,000+ vehicles

These scan tools are compatible with around 99% of the vehicles on the market worldwide. With support for more than 150 car manufacturers and 10,000 plus models, you won’t run into compatibility issues with any of these devices. 

The tools are capable of diagnosis on all modules, and these include:

• ECM
• TCM
• ABS
• SRS
• TPMS
• And more

Conclusion: Which one you should buy

The Pros Mini and Diagun V are great advanced-level scanners capable of diagnosing almost all your car problems. With both offering similar functionalities, which one should you consider purchasing?

PROS Mini – If you want a better one

From my experience, I believe that the Pros Mini is a better device of the two simply due to the superior hardware it boasts over the Diagun V. 

For around $80 more, the Pros Mini has a larger screen, more computing power, and a more-than-decent battery. All these hardware differences justify the slightly more expensive price tag.

I’ve run into a lot of crashes testing devices with a smaller processor. For me, the quad-core 1.3 GHz chipset on the Pros Mini is more than sufficient for a seamless experience.

Diagun V – A decent affordable option

With exactly the same functions, Diagun V can actually be a better choice for you since it’s slightly cheaper. Even though its processing speed is slower, the gap is not that significant. And if that’s not really your concern, go for Diagun V!
