🔧 Troubleshooting Power Limitations

1. Device Power Management

   • Devices prioritize power needs (e.g., laptops require CPU/GPU stress tests for full power draw)

2. Measurement Best Practices

   • Avoid inline meters causing voltage drop - measure input/AC-side power

3. Voltage Requirements

   • 20V output requires ≥20V input (19V input → 15V output max)

4. Power Budget Rule

   • Input ≥ Output × 1.05 (e.g., 105W input for 100W output)

🚨 Critical Warnings
• SuperVOOC 65W requires ≥70W PD/DC input
• Phone chargers may cause reboot loops - Use only laptop-grade PD/DC adapters
• Returns due to improper power supply will incur shipping fees

🔌 Connection Guides

Typical Applications
• Convert high-power PD/DC supplies to SuperVOOC/SCP
• Enable multi-protocol charging for phones/tablets using:

• 100W+ PD power banks

• Laptop chargers (65W-140W)
