This right here is the Anker Powerline+ II which is the strongest cable ever created. This power cord can support weight up to 175 lb, which is kind of strong! It won’t even get damaged when you use this cable as a jump rope, pulling weight, and etc. The cord has a high speed charge of 3A. The price for this depends on the size of the cable which you can decide on amazon. Also, Anker is famously known for its best customer service to customers. This cable also has a 2 shade nylon braiding which will feel smooth. Lastly, this cord can be bent up to 30,000 times which lasts 30X longer than the original cables that comes with the phone.
This item relates to engineering, because you need to build the high quality wires and metals which each is one part of a wire. It then requires the nylon braiding which is also done by mechanical robots.
