USAMS CC331 T70 40W 4-Port GaN Fast Wall Charger (2x USB-C + 2x USB-A)

Clear out the cluttered power strips with the ultra-efficient USAMS CC331 (T70 Series) 40W GaN Wall Charger. Built with next-generation Gallium Nitride (GaN) semiconductor material, this compact power adapter handles higher power conversion and operates at much cooler internal temperatures than standard chargers, all while packing a heavy-duty 4-port layout into a remarkably travel-friendly frame.

The CC331 features an optimal "2A + 2C" balance, providing two high-speed Type-C Power Delivery (PD) ports alongside two rapid USB-A Quick Charge (QC) ports. When powering a single device, individual ports supply up to 20W (USB-C) or 18W (USB-A) of direct power—making it perfect for fast-charging your flagship iPhones, Samsung Galaxy phones, or tablets simultaneously. An integrated dynamic power delivery chip tracks connected electronics in real-time to adjust voltages and maintain ultimate charging efficiency.

Key Features

• 4-Port Synchronous Charging: Outfitted with 2x USB-C and 2x USB-A ports to keep your phone, tablet, wireless headphones, and smartwatch energized at the exact same time.

• 40W High-Efficiency GaN Core: Advanced Gallium Nitride circuitry allows the unit to run cooler, lose less energy to heat dissipation, and remain highly compact.

• Universal Protocol Support: Fully compatible with a wide array of fast-charging architectures including PD 3.0/2.0, QC 3.0/2.0, AFC, and FCP.

• Intelligent Battery Protection: Automatically shifts to a conservative trickle-charging rhythm once your connected device reaches 80% capacity, lowering stress on internal lithium batteries.

• Global Voltage Readiness: Seamlessly supports a wide input voltage range (110V–240V), making it the ultimate multi-device traveling accessory for domestic and international trips.
