I wish I would have found this out sooner, but I recently purchased this 5 amp USB-C car charger: https://goto.walmart.com/c/1943169/...Google-Pixel-Pixel-XL-Galaxy-S8-S8-/123030824 and I now have fast charging in the car. Seems just as fast as with the stock MS charger. It also has a nice coiled cable, an additional USB port and feels very high quality.
