Port Reference and Power Allocation

The 145W USB-C 4-Port GaN Travel Charger delivers up to 145W total across four USB-C PD ports. Power is shared dynamically based on the devices connected.

• Port 1 — Up to 100W when used alone; recommended for MacBook Pro, MacBook Air, or other USB-C laptops requiring high wattage.
• Ports 2–4 — Up to 45W each for tablets, phones, and accessories.
• Total output — 145W shared. When all four ports are in use, each port reduces wattage proportionally to the connected device's needs.

Troubleshooting

• Device is not charging — Ensure the USB-C cable is fully inserted. Try a different cable. Verify the device supports USB-C PD charging.
• Outlet adapter feels loose — Remove and re-seat the adapter. Slide it firmly until it clicks into the locked position.
• Charging speed is reduced — Multiple high-draw devices sharing the 145W limit will reduce individual port speeds. Disconnect unused devices to increase wattage to the primary device.
• Charger is warm during use — Normal under heavy load. Ensure ventilation. Do not cover or stack the charger.
