Keep your vehicle's health in check without a trip to the mechanic. The KW905 is a compact Bluetooth OBD2 scanner that plugs directly into your car's 16-pin OBD port and pairs with the free MAXOBD app on your phone, giving you instant access to engine fault codes, live sensor data, and drive-cycle verification. It's built for 12V gasoline and diesel vehicles and works with over 100 car brands and 100,000+ models, covering vehicles sold in the US since 1996, Europe since 2001, and Asia since 2004.

Once connected, the KW905 reads out real-time parameters such as vehicle speed, RPM, fuel consumption, engine coolant temperature, fuel pressure, calculated engine load, and throttle position, helping you catch problems early and avoid unnecessary shop visits. A built-in ON/OFF switch keeps it from draining your battery when the car is parked, while low-power sleep mode and high-speed Bluetooth communication keep everything running smoothly. Small, durable, and easy to use, it's a practical diagnostic companion for everyday drivers and DIY mechanics alike.

well

The device seems good...since my car is at the workshop, I will test it when I return.

It worked great and the app does the job.

I'm still looking into other, better apps which i think will just work - when i have time for it.

Two weaknesses:

1. The loop that comes with it is a bit unnecessary imo; how is it useful?

2. The on-off light indicator is too weak.

Arrived quickly. Looks like it's of good quality. Haven't tested it yet. The application has been installed. I recommend it.

The Huawei phone does not support the app. :(

Fast delivery and well pack. download the maxbd app and try out. most of the features support but not all. well base on the money paid still acceptable.

Support the use of the pyclip program for diagnosing renault vehicles. This program allows scanning all control modules of the vehicle

Received. Works perfectly. Connection OK.

Good quality product, properly secured during delivery, I recommend the seller, I may shop here again.

Looks quality but haven't tried it yet. everything ok, recommended seller

Received my order in two weeks. Great quality! You can useeither with its own app or any other app. Does work with myiphone.

Excellent quality. Works with iphone.

Works impressively well and reads codes correctly. I didn'texpect much for the price. Impressive! Used it on my w202and it worked.

"i recently upgraded from a wired scanner to the konnwei kw905 bluetooth obd2 on my 2013 jeep grand cherokee, and it’s been a game-changer. I mostly use it whenever my check engine light comes on, and it quickly gives me clear, real-time diagnostics right on my phone through a fast and stable bluetooth 5.2 connection. The app’s intuitive interface and visual data make understanding engine codes and battery status straightforward, even if you’re not a mechanic. Compared to my old, wired device, this scanner is far more convenient and user-friendly, with smart features like a power button and led indicators that help save battery life. For anyone who wants quick, reliable insights when that dreaded light pops up, this wireless tool is a must-have. A++++ highly recommended.

Tested on a diesel and gasoline vehicle. Works excellent.

The only device that worked in my car.

Best price-performance ratio

Excellent, it meets everything stated and works perfectly on iPhone. I recommend it.

Arrived within the deadline, very good product, the app is a bit limited in some functions.

It's really, really cheap and the product is useful and I'm using it well.
Use it well in the vehicle and in the app.

Got it within a week! fast delivery and perfect product

Not working on 2026 cars

spectacular, as my Guatemalan-Peruvian friend would say

spectacular. Good service, works perfectly.
just connect to the OBD2
and downloading the Maxobd app serves as a keychain, it scans and clears codes, and you can monitor various parameters of the car in real time.
