I've tried so many different USB-C PD chargers, big and small, from Apple, Anker, Aukey, Zendure. This charger seems too good to be true. That's about 2.4 inches by 1.2 inches by 1.2 inches, or the size of two of Apple's tiny standard 5W iPhone chargers stacked on top of each other. However, it fully supports the USB-C PD 3.0 specification at 60W, which means it can charge any USB-C device (as well as iPhone at high speeds with the official Apple USB-C to Lightning cable). . I confirmed that my Macbook was indeed charging with the 60W charger. It's not cheap by any means, but it's incredible technology provided it lasts. I've only had him for a few days. This is truly the reference USB-C PD charger for the entire industry.
