Allows you to charge SURFACE devices via a 45W 15V3A USB-C Power Delivery (PD) Wall Charger or Power Bank. You only need to carry a single USB-C charger to charge multiple devices, including SURFACE. It is lightweight and easy to carry. Can also be used as a backup charger. Requirements: This cable requires a USB-C charger or power bank that supports 45W 15V3A output. The female USB-C charging data cable also requires a USB-C cable capable of carrying 3A current. Double-check your USB-C charger to ensure it lists "15V/3A" in the specifications. Some PD chargers do not support all cables. It is recommended to use the data cable with a GaN 3-port USB-C charger to avoid compatibility issues. Please refer to the product details page for more information. Material: The inner core is made of pure copper cable, which effectively reduces heat and ensures safety.
