Heres the Amazon link. It has Amazon choice status and mostly good reviews, so I think the charger is legit. Plus I've used it with my phone and have let other people use it to charge their laptops. I spoke with a MS store manager about this, and he's the one who told me not to use type-c for charging. He said he's spoken with the people who designed and engineered the book 2, and that they recommend against type-c charging.
