I tested 20+ ELM327 adapters myself on multiple cars (Toyota Corolla 2022, Mazda 2 2004, Renault Kangoo 2005, Fiat Punto 2003, and multiple others) to find out which ones are worth buying! I will also give you a list of the best OBD2 apps to use with your new adapter 🙂

Testing & comparing

Tester & Author: Juraj Lukacko
I care about giving you guys the best value-for-money tools as I am a DIY mechanic myself and I am sure I don’t want to spend money on crappy tools 🙂
I test new diagnostic tools every week, so I don’t just offer a few random products.
I have personally tested more than 100 car diagnostic tools, so I understand which ones are worth purchasing.
You can read the full review policy HERE, but now check what I found:
I tested a lot of ELM327 adapters
I tested 12+ different adapters in terms of ease of use, compatibility with operating systems (Android, iOS, and Windows), and also adapter’ speeds.

The test is only for ELM327 adapters
All of these are Bluetooth OBD-II scanners, but not all of them are ELM327. For this review, only ELM is included but if you are looking for a more professional Bluetooth OBD, you should check out the J2534 Bluetooth scanners comparison.

Vgate Icar PRO2s is a great value
Unlike a lot of adapters that gave me a hard time connecting, the Icar PRO 2s were completely different. It does work straight out of the box without me having to spend half an hour on pairing.

It also has a sleep function so it will not drain your battery and decent speed for its price which will be enough for almost all apps you can use with your ELM adapter.
By the way, here are the Best OBD-II apps for your ELM327 adapter, you can use 🙂
I am recommending Vgate Icar PRO 2s for everyone looking to get the first adapter. There are of course some $5 adapters on Aliexpress but some of them are scams as they do not include the ELM chip so are useless.
Some of the $5 adapters might work but without a stable connection or you even won’t get it to pair with your phone. Just save yourself headaches and avoid these kinds of adapters.
Vgate Icar PRO 2s is not that expensive, check out a separate review (there are links to different stores to find the best price)
OBDLink MX+ is great but expensive
OBDLink MX+ is definitely the best ELM327 you can buy but it comes with a price. It is the most expensive adapter on this list.

It does have a stable and extremely fast connection which is recommended if you plan on doing any ECU coding (unlocking hidden car features) to avoid damage to your control modules.
It also is a good choice to track performance data as lower-speed adapters might have trouble keeping up with that much data (engine parameters logging).
You are also getting access for free to the OBDLInk smartphone app and OBDwiz Windows app if you buy OBDLink MX+.
Check out more about OBDLink in a separate review.
Vlinker MS is great alternative for OBDLink
If you like the idea of having a premium ELM327 adapter but OBDLink MX+ is outside your budget, the Vlinker MS can be ideal for you.

Still has a similar speed to OBDLink, a sleep function, and even the same pairing button to keep the connection secure and only available to your phone.
It doesnt give you access to specialized apps like OBDLink, you can only use those that work for all other adapters.
Veepeak is budget-pick for Android users
I have used Veepeak for 2+ years with my Android phone and it still works fine even though it was the cheapest on this list.

It is enough to read/clear fault codes or even do some advanced stuff like ECU coding. I used it to unlock the window opening and closing on my Toyota Corolla with Car Scanner App.
