The Autel MaxiCheck MX900 has emerged as a major talking point in the 2026 DIY car repair community. While newer vehicle architectures demand more advanced connectivity, choosing between the cutting-edge MX900 and the proven MK808S depends entirely on your specific fleet and budget. After six months of testing, here is an objective breakdown of where each tool excels.
## Evolution of Connectivity: Native CAN-FD & DoIP
Modern vehicle diagnostics are shifting toward faster protocols, creating a fork in the road for users.
- The MX900 Advantage: It features built-in support for CAN-FD and DoIP, making it a seamless solution for 2023+ GM, Ford, and Chrysler models without the need for external hardware.
- The MK808S Value: For vehicles manufactured before 2020, the MK808S remains highly effective. While it requires an external CAN-FD Adapter, it provides a cost-effective entry point for enthusiasts who don’t frequently work on the latest vehicle platforms.
## Hardware Comparison: Performance vs. Proven Utility
To help you decide if the hardware jump is necessary, here is a direct comparison of the two models:
| Feature | Autel MX900 | Autel MK808S |
|---|---|---|
| OS | Android 11 | Android 11 |
| Display | 8-inch high-res screen | 7-inch LCD screen |
| Protocols | Native CAN-FD & DoIP | Requires Adapters |
| Boot Speed | ~40% Faster | Standard |
| Graphing | 8 PIDs Simultaneously | Standard |
| Best For | Modern/New Vehicles | Budget-Conscious DIY |
## Practical Maintenance Capabilities
Both tablets function as capable bi-directional controllers, allowing users to perform active tests.
- Shared Strengths: Both tools successfully perform ABS Brake Bleeding, Injector Coding, and Active Tests (like forcing fuel pumps or fans).
- Operational Experience: The MX900 offers a snappier UI and smoother live data graphing. However, for basic maintenance tasks on a weekend project, the MK808S provides identical diagnostic results.
## The “Reality Check”: Long-term Costs
- Subscription Tiers: The MX900 carries a higher annual renewal fee than the MK808S (Discounts for Autel Software Subscription). Users must weigh the convenience of native protocols against the lower long-term cost of the 808 series.
- Functional Ceiling: Both tools are focused on Coding and maintenance. If your work involves Programming blank modules, you will still need to step up to the Ultra series.
## Final Verdict: Which One Should You Buy?
- Choose the Autel MX900 if you regularly maintain 2023 or newer vehicles and want to eliminate external adapters for a faster, professional-grade workflow.
- Choose the Autel MK808S if you are looking for the best value for money and primarily work on vehicles made before the massive shift to CAN-FD/DoIP protocols.
