7. Safety Information

The USAMS Magnetic GaN Charger is designed with multiple safety features to protect your devices and ensure safe operation. These protections include:

• Over-current Protection
• Over Power Protection
• Over Voltage Protection
• Short Circuit Protection
• Flame Retardant Protection
• Lightning Protection
• Over-temperature Protection
• Anti-jamming Protection

Always use the charger in a well-ventilated area and avoid exposing it to extreme temperatures or moisture. Do not attempt to disassemble or modify the charger.

8. Troubleshooting

• Device not charging: Ensure the charger is securely plugged into a working power outlet. Check that the charging cable is properly connected to both the charger and your device. Try a different cable or device to isolate the issue.
• Slow charging: Verify that your device supports fast charging protocols (USB PD, BC1.2) and that the cable used is also fast-charge compatible. If charging two devices, the power output is shared, which may result in slower charging for each device compared to single-device charging.
• Charger overheating: While the charger has over-temperature protection, ensure it is used in a well-ventilated area. If it feels excessively hot, disconnect it immediately and allow it to cool down. Avoid charging in direct sunlight or enclosed spaces.

9. User Tips

• Laptop Charging: Yes, this charger is capable of charging compatible laptops that support USB Power Delivery (PD) up to 35W. Ensure your laptop's power requirements do not exceed 35W for optimal performance.
• Modular Power Bank: The modular part of this charger can function as a power bank. The video indicates a capacity of 18000mAh with 45W output for the power bank module (sold separately). This provides portable charging when a wall outlet is not available.
• Cable Management: The retractable cable is excellent for travel. Always ensure it retracts smoothly to prevent damage.
