Easy solution to failing iPhone chargers

ok I seem to buy a iPhone charging cord every other week no matter what I do or what people say to do they still wear out . I don’t care how careful you are it won’t work that long it’s all bs. Why don’t they just come up with a plug in charger like what you plug headphones with ??? I’ve only seen had one . . .A tablet that had this option in it the rca tablet , cheapest tablet in the world . in fact I.have never had to buy any kind of cord for this . I simply plug it in like headphones and then plug it in . Last at least 10 to 20x longer than the frustrating nickel and dime apple cords that they make a killing from. I read all these post on how to make them last longer and just laugh when all the would have to to is make another jack connection just like your headphones but smaller. Why on earth don’t they do this . I couldn’t be the first one to come up with this simple idea?
