MK808S vs MK900 Key Specs
Screen size
Edge: Autel MK900 8-inch DoIP Scanner
The Autel MK900 features an 8-inch display, which provides 20% more viewing area compared to the 7-inch screen on the MK808S. This larger panel offers higher resolution, allowing you to see data waveforms more sharply. The extra space makes navigating menus and reading live data streams more comfortable during complex repairs. The MK808S uses a standard 7-inch display that is sufficient for most tasks but lacks the expanded canvas of the MK900. If you prefer a larger interface for better visibility, the MK900 has the clear advantage.
Service functions
Edge: Autel MK900 8-inch DoIP Scanner
The MK808S includes 28+ hot service functions, covering essential resets like oil, BMS, SAS, and injector adaptations. The MK900 upgrades this to 40+ hot services. It adds twelve new 2026 features, including Transport Mode, HV Battery checks, Rain/Light Sensor resets, and Control Unit resets. Both tools handle core maintenance tasks, but the MK900 offers a broader menu for newer vehicle systems. If you need access to the latest service protocols for modern cars, the MK900 provides more capabilities out of the box.
Connectivity
Edge: Autel MK900 8-inch DoIP Scanner
The MK808S relies on a wired OBD-II connection, which ensures zero-lag response and rock-solid reliability without Bluetooth interference. The MK900 also offers a stable cable connection but adds dual-band Wi-Fi (5GHz and 2.4GHz). This allows for wireless printing of pre- and post-repair reports and easier cloud management via QR codes or email. The wired link remains the most stable option for live data, but the MK900 gives you wireless flexibility for documentation and sharing results with colleagues or clients.
Protocol support
Edge: Autel MK900 8-inch DoIP Scanner
The MK900 supports CAN-FD and DoIP protocols, which are necessary for diagnosing newer 2020+ GM and Jeep models. This removes the need for extra adapters. The MK808S data does not explicitly list these advanced protocols, focusing instead on standard coverage. Both tools handle full-system scans across engine, transmission, ABS, and body systems. However, if you work on vehicles requiring DoIP or CAN-FD communication, the MK900 is the only option that natively supports these standards without additional hardware.
Software updates
Edge: Autel MK900 8-inch DoIP Scanner
The MK900 includes one year of free software updates, ensuring you stay current with new vehicle coverage and features. The MK808S data does not specify a free update period, noting only an annual renewal fee. Both tools share the same CPU and core diagnostic functions. The MK900’s included update year provides immediate value, whereas the MK808S may require immediate payment for updates. If you want guaranteed updates for the first year without extra cost, the MK900 is the better choice.
