Where can you buy a iPhone charger that can last long?

My previous IPhone 5s charger broke and that's last long maybe 9 months so I bought another one from the mall but it wasn't from a store I bought it to one of the stands that sells phone cases and charger and it cost $15 and it only last for 3 days and I got the message this accessory may not be supported so where can I get a real iPhone charger? And how much is the charger cost Apple Store? Btw I have iPhone 5s thanks!

I don't know where to find a good charger but when my mom had an I phone the charger broke at the bottem where it goes into the phone. Buy a regular charger and when you get it put a small spring around the part where is breaks so when your I phone is charging the charger won't bend.look it up on pinterest and you will find a picture of how to do it.

I've never had an issue, most people are lazy and just yank the chord with their hand to unplug it. Thats why you end up buying new ones.
