Supplier's note

  1. Key Breakthroughs:

    • Global Compliance: RoHS/CE certifications ensure safe, eco-friendly use across regions.
    • Universal Compatibility: Supports 5+ OBD-II protocols, covering 95% of post-1996 vehicles.
    • SDK Integration: Allows firmware customization for brand-specific diagnostics.

  2. Version Selection Guide:

    • Base Model: Best for DIYers needing basic DTC scanning and live data.
    • Advanced Model: Ideal for professionals requiring Bluetooth-enabled remote diagnostics and faster scans.
    • Pro Model: Tailored for fleet managers or technicians needing multi-protocol support and wireless connectivity.

With the Pro’s 12-protocol capability, you can diagnose hybrid/electric vehicles—unavailable in base models. Pair this with its low power draw (2W) to ensure all-day field use without battery swaps.

*Note: The "+30%" in protocols reflects expanded compatibility with emerging vehicle standards (e.g., UDS for EVs).
