Port Reference and Power Allocation

The 200W USB-C 6-Port PD GaN Charger provides six USB-C PD ports with dynamic power sharing. Maximum power per port depends on how many ports are in use simultaneously.

• Port 1 (top) — Up to 140W when used alone; ideal for high-power MacBook Pro, MacBook Air, or large USB-C laptops.
• Ports 2–6 — Up to 20–45W each when charging multiple devices. The charger automatically negotiates the appropriate wattage for each connected device.
• Total output — 200W shared across all active ports.

For fastest laptop charging, use Port 1 and avoid plugging in additional high-draw devices simultaneously.

Compatibility

The 200W USB-C 6-Port PD GaN Charger is compatible with any USB-C PD device, including MacBook Pro, MacBook Air, iPad Pro, iPad Air, iPhone, AirPods, Apple Watch chargers, Android phones, and USB-C Windows laptops. A USB-C charging cable is required and is sold separately.

Troubleshooting

• Device is not charging — Confirm the cable is fully seated in both the charger and the device. Try a different USB-C cable. Verify the device supports USB-C charging.
• Charging speed is slower than expected — Total output is shared across all ports. Disconnect unused devices or use Port 1 alone for maximum wattage delivery to a single laptop.
• Charger feels warm during use — Warmth is normal during high-load charging. Do not cover the charger or place it on insulating surfaces. Ensure adequate ventilation.
• Device shows "Not Charging" on screen — Some devices require a minimum wattage to charge. Disconnect other devices to free up more power for the target device.
