USB-C Charging Cable Meets the Demands of a Variety of Devices This two-in-one USB Type-C charging cable accommodates two USB-C devices using a single USB-C charging port. The U420P-2X4-140W supports up to 140W (28V 5A) of power to a single device, including the latest high-power laptops and MacBook Pro M3/M4 models. When charging two devices simultaneously, this cable automatically allocates available wattage depending on the voltage requirements of each device to ensure safe, reliable charging. Note : To support full charging capabilities, the connected USB-C charger must support PD 3.1 charging up to 140W. See the Owner’s Manual for complete power allocation per port information. Dual Charging Output Design The total length of the U420P-2X4-140W is four feet (1.2 meters) with a three-foot USB-C male input connector and two one-foot USB-C male connectors. Though the cable is primarily intended for charging, it also supports USB 2.0 data transfer speeds up to 480 Mbps for syncing a single device during charging. Note : When using this cable to transfer data, do not connect the input (single connector) side of the cable to a charger or any other power source except the source computer. Doing so may lead to electrical feedback and cause damage to the connected storage devices. Compatible with Many Different Charging Profiles The U420P-2X4-140W charges a variety of USB Type-C devices due to the different charging profiles it supports. It is compatible with USB-C Power Delivery (PD) 3.1 and PD2.0+PPS (Programmable Power Supply) for modifying voltage and current to provide optimal charging to a connected device based on its actual needs. These standards can operate together to ensure your device is receiving the proper currents and voltages between the device and the charger. This cable also supports Quick Charge (QC) 3.0 for charging a single QC-compatible device quickly (up to 80% in just 35 minutes).
