The charging cable must be equipped with a USB-C (PD) wall charger or a charging bank with a power of 45W (15V3A) or more to charge the Surface device. It is very light and portable, and is the best choice for standby charger. (Note: carefully check the USB-C charger to ensure that the power is "15V/3A". Otherwise, the best charging efficiency will not be achieved.)
Compatible with Surface Pro 7, Surface Pro 6, Surface Go/ Go 2/ Go 3, Surface Pro 5(2017), Surface Pro 4, Surface Pro 3, Surface Laptop 4/ Laptop 3/ Laptop 2/ Laptop 1. When the cable works with the Surface Pro 8/9/Surface Laptop 5, you will see the prompt card of "connected with a slow charger". Don't worry. This is due to technical limitations, but the power match you anytime and anywhere.
