That's an interesting theory. I assumed it's because in their removing of harmful materials from their cables and cords they have made the cords much worse. This was especially noticeable with the early lighting connecters. I think the cables simply can't handle that level of stress from being wound that tight.Why? Because it no longer has a permanently attached (captive) output cable. Those wrapping hooks were for "cable management", so there would not be a long cable dangling in a bag or carrying case. A discrete USB PD cable is much easier to manage alone, than a dangling captive cable.
Yes, one may choose to use an accessory to aid in cable management: a little string to tie a bow, rubber band, button and loop (such as Bongo Ties), stretchy belt/strap with button holes (like Dell 5T339), twist tie wire, hook and loop (Velcro), self-sticking tape (such as bandage tape 3M Vetrap). There is a wide selection of fashionable cable accessories including: cable clips (such as Nice, Inc. Snap CableKeep), cable "tacos", straps like bracelets with magnets or snaps, frames to wrap around like a spool or yoyo or skeleton.Yeah but you'd have to use a rubber band or something
Every manufacturer recommends against doing this and even warns you to do it. This is THE way to destroy your cable because you are wrapping a warm cable around a warm power adapter. When it cools the cable will shrink and the wrap will be too tight. This causes increased wear and tear on the cable which greatly reduces its lifespan. Never ever do this with any power adapter whatsoever! The prongs on the older Apple power adapters should have never been on the power adapter at all. They finally get rid of them.Or wrap it around the brick and tuck in the end. That's what I do.
x1000000000From a design perspective: In order for those hooks to work one end of the cable needs to be fixed to the charging block, and the other end needs the small "U" shaped part to connect itself to the cable.
The removable cable is a much better design as wrapping those hooks tightly guaranteed you'd need to buy a whole new power brick after a couple of years.
I use this exact product also...tons of them. They are like a gift from the heavens.I use Velcro cord wraps on all my cords - example (only $10 for 100):
