Charge Your Surface with USB-C This cable allows you to charge your Microsoft Surface devices using any USB-C PD charger or power bank that supports 15V/3A (45W) output. Perfect for travel — share one charger with your Surface, phone, and other USB-C devices. No need to carry the bulky original charger. Compact, lightweight, great as a spare Power Requirements To ensure proper charging, your USB-C charger must support 15V/3A output. Most phone or tablet USB-C chargers do not support 15V and will not work. We recommend using a 45W PD charger or higher that clearly lists 15V/3A Required Input: 15V/3A Max Output: 15V/2.6A（39W) Recommended Power: 45W or above Not compatible with 18W, 24W, or 29W chargers Phone/tablet chargers usually won’t work Compatibility Surface Pro 11/10/7/X/6/5/4/3, Surface Laptop 1/2/3/6/7, Surface Book 1, Surface Go 1/2/3/4 Also compatible with Surface Pro 8/9 and Surface Laptop 4/5/6 (15"), but may show “Slow charger connected” — this does not affect charging performance Troubleshooting 1. LED flashes: This means your charger has insufficient power. Please use a USB-C charger that supports 15V/3A and 45W or above 2. Phone or tablet charger doesn’t work: Most phone and pad chargers do not support 15V output or have less than 45W power, and therefore cannot be used. Older USB-C chargers also may not meet the requirement 3. LED does not light up: Try using a different 15V/3A 45W charger. If it still doesn’t work, please contact us via your Amazon order page or seller profile This cable only supports charging. It does not support data transfer or video output
