I just thought that I would share my experiences with the Dell 90 watt charging adapters. I used to go through one every year on my work laptop when I used the velcro strap to secure the wire in a bundle. Now I just slightly coil it up and I've now been using the same adapter for many years. Maybe this will help someone, that cable is just co-ax and isn't meant to be bent often.
Now I cringe when I see people tightly bend those cables. Our Systems admin guy just did one the other day.
I had to get the CEO at a past job to suggest the same thing to our salesmen (they wouldn't listen to me) because I was replacing so many adapters every year because of broken plugs. crack wires etc ...
