TECH REVIEW: HYZUO – Surface Book Pro 4 Power Adapter (65w) with bag REVIEW:
For about $30 and pretty fast shipping from Amazon, the Hyzuo Surface Pro 4 65w power supply works. I didnt like the kink in the cord when I opened it. overall it works just like the original power supply. The USB port works on the power adapter as well. We will see how long it lasts.
