I like my Surface Book 2 15β. What I don't like is the extra weight. The SB2's battery lasts a full day and then a little more. However, the power block it came with is large and heavy. I don't want to take it with me in case it runs out. This power supply is tiny in comparison. It's slower than what came with the SB2, but it's still a decent 65W (60W goes to a laptop) and well worth the trade-off.
