Recommendations
1. For Professional Mechanics (Advanced Features)
TOPDON ArtiDiag 900 BT: Best for professionals needing bi-directional control, special functions, and extensive vehicle coverage (130+ brands). The 7-inch display and 6300mAh battery strike a balance between portability and performance.

2. For Heavy-Duty Use (Long Battery Life)
TOPDON UltraDiag or AD900 Lite: Both feature a large 8-inch display and a massive 10000mAh battery. Ideal for prolonged diagnostics, but with fewer service functions (8 vs. 28) and limited vehicle coverage (65+ brands).

3. For Beginners or Budget Users
TOPDON ArtiDiag 800 BT: Affordable entry-level option with basic diagnostics (110+ brands) and free software updates. Lacks advanced features like bi-directional control, but covers essential needs.

4. For Multi-Language Support
AD800-BT or AD900-BT: Support 17 languages, making them suitable for non-English users. UltraDiag and AD900 Lite have limited language options.
