I don't think there's a USB-C charger out there that can actually pump out anything close to their rated maximum.
I got it for 110€ in some Amazon bundle together with 3 usb cables. Which is about the price of the 140W Apple brick. (We don't get the powerbricks included with the MacBooks.)
But Apple's is much larger, heavier and has a single port.
And it’s much lighter? Nice, wishlist!
