Product weight: 28g body size: 74 (L) × 26 (W) × 12 (H) mm working temperature: - 20 ℃ to + 70 ℃ 1.5 product advantages and highlights:

1. The built-in triode over-voltage protection will not burn the machine when it is under 100V high voltage

2. The built-in backup battery can still work for 2 hours after power failure. If the terminal is removed, there will be a power failure alarm

3. The built-in acceleration sensor can judge whether the car is driving or stopping without connecting ACC line, so as to prevent static drift

4. Mtk6261 chip is adopted, with stable performance and EPO auxiliary positioning function

5. Built in watchdog Dual CPU, can prevent crash

6. Low power consumption during sleep, preventing battery from losing power

7. It can prevent reverse connection. If the positive and negative poles are reversed, it will not burn the machine

8. The power line is equipped with fuse, and the short circuit of the equipment will not damage the battery of the original vehicle

9. Powerful blind area supplementary transmission function, without losing track for 1 hour

10. The turning point is powerful and almost perfect

11. Beidou +GPS+LBS three mode positioning, pseudo base station identification

12. Compact body: size of lighter
