1. Interface Type:USB / Type-C 1 / Type-C 2 / USB-Micro / Lighting 2. Power Supply Port Type:Type-C 3. Output Current:1A 4. Output Voltage:5V 5. Product Size:About 48.5x45mm 6. Net Weight:About 12g 7. The measurement allowed error is +/- 1.0-2.0cm 8. All 4 indicator lights are on, then the data line is normal (double-head type-C data line requires all 5 indicator lights to be on). 9. If VCC or GND is not lit, it indicates that the charging function of the data line is abnormal. 10. D+ or D- is off, indicating that the data transmission function is abnormal. 11. CC is dedicated to double-head type-C data line detection. When testing other data lines, the light will not turn on. 12. The operation is simple, the detection is convenient, and the detection efficiency of the data line is improved. 13. Uncompromising performance in an ultra-light body,heavyweight performance without the weight.
