KABCON102w Charger for Surface

My original one comes with 12v and 2.58a out (maybe 36w), the model is 1625. so i wonder that whether this item will do harm to my surface pro 4?

Will this work with both the 13" and 15" versions of the Surface Book 2? The original chargers are different and will only work on one or the other.

Does this work for the new Surface Pro (2017)?

Will this work with the surface book?
