Allows you to charge your Surface devices via 45W 15V3A USB-C Power Delivery (PD) wall charger or power bank. You only need to bring a USB-C charger to charge many devices, including Surface, on the go. It is very lightweight and portable. It can also be used as a spare charger. Requirement: This cable requires a USB-C charger or charging bank that supports 45W 15V3A output. The female USB-C charging cable also needs to support 3A current. Double-check your USB-C charger to ensure it lists "15V/3A" in the specifications. Some Apple PD chargers do not support this cable. It is recommended to use the cable with our GaN 3-Port USB-C charger to avoid compatibility issues. Please find the link in the page details.
