1. Product Overview
The AUTO-VOX USB Charger DC 5V to 12V Charging Cable is designed to power compatible AUTO-VOX wireless backup camera monitors directly from any standard 5V USB port. This eliminates the need to occupy your vehicle's 12V cigarette lighter socket, providing greater flexibility for power access in cars, RVs, or other settings. The cable features advanced step-up circuitry to ensure a stable 12V output from a 5V USB source and includes a 4-pin connector for direct compatibility with specific AUTO-VOX backup camera systems.

5. Troubleshooting
If you encounter issues with your USB Charger cable, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitor screen blinks or flickers. | Unstable 5V USB power source or insufficient power delivery. | Ensure the USB port provides stable 5V power. Try a different USB port or a higher-quality USB power adapter/power bank. The cable's advanced circuitry minimizes this, but a weak source can still cause issues. |
| Monitor does not power on. | Cable not properly connected, USB power source is off, or cable/monitor malfunction. | Check all connections (4-pin to monitor, USB to power source). Ensure the USB power source is active. Press the inline power switch on the cable. If the issue persists, test with a different compatible monitor or contact support. |
| Inline power switch does not respond consistently (e.g., turns off but not on). | Switch malfunction or temporary electrical anomaly. | Unplug the USB cable from the power source for a few seconds, then plug it back in. If the issue persists, the switch may be faulty. Contact AUTO-VOX customer support for assistance. |
| Cable does not fit the monitor. | Incompatible monitor model. | Verify your monitor is one of the compatible models (S3A Plus, Solar4B, Solar 5A) that uses a 4-pin power input. This cable is specifically designed for these systems. |
