Redesigning phone charger engineering project
hello, I am currently doing an engineer project at college and would appreciate if you could give me some consumer advice. I am redesigning a phone charger plug, to improve portability and make it well engineered by introducing a spring loaded button for the pins and a reel to make it self contained.
what would you as a consumer look for in a product like this?
What do you not like in regular phone charger designs?
Are there any other improvements?
Any feedback would be much appreciated and used. thanks, Sam
