127W AC Adapter for Surface

The GreenTechLLC US7-00001 delivers 15V at 8A for a total of 127W output. It replaces Microsoft OEM part numbers US7-00001 and USY-00001 across a wide range of Surface Book, Laptop, Pro and Go models. A built-in USB port supplies 5V at 1A for charging phones or accessories.

Compact design with USB charging

The black adapter measures 5.75 x 2.3 x 1.2 inches and weighs 1.3LB, making it easy to carry in a laptop bag. Its proprietary Surface connector mates securely with the device charging port. The extra USB-A port adds a convenient 5W output without needing a separate wall charger.

Replaces lost or worn OEM units

This unit suits owners who need a direct replacement for a missing or damaged original adapter. It is not for users who require a higher wattage supply than 127W or a different voltage standard. The jump is worth it when the original brick fails or a spare is needed for travel.
