Black charging cable with a magnetic connector specifically for Surface devices and a USB-C connector. - Cable Color: Black - Cable Length: 1 meter Thank you for viewing. I used this with a Surface Pro 7. Please note that the USB-C side requires an output of 35W or more. I used a 35W cigarette lighter adapter to charge it in my car. It's much more compact than carrying the heavy original power adapter, so it was very useful. For those who appreciate its convenience, please consider purchasing.
