My magnetic USB-C cable finally arrived at the end of last week, and I have the tip installed on the right side of my MBP, taking up one of the precious USB-C ports.
First impressions? The cable itself seems to be a good quality braided cable. The magnetic tip protrudes from the laptop a little more than I’d like (oh, Apple, why did you not embed this in the laptop and do MagSafe over USB-C?).
The magnet itself, while sold as using the “world’s strongest magnets” do not appear overly strong, My old MBP’s MagSafe connector was held better (although I think the recess into the case helped with that a bit too). This holds well enough, and there is a nice blue LED in the end of it to tell me when it is connected. It doesn’t have the orange/green color change that the Apple cables had, but I assume that is lack of a signal back from the battery. The blue light is better than the standard Apple USB-C cable though which had no visual indication that it was connected and power was flowing.
Conclusion? Not as good as MagSafe, but definitely good enough and it restores my confidence that if one of the kids trips over my power cord, the expensive MBP won’t go flying onto the floor.
