Which charger is best for my iphone 5?

My official iphone 5 charger broke, so I've been buying cheap non official ones from the Internet, which keep breaking, and then I've had to keep re purchasing them. I'm buying an official one if the one i have now breaks again. But is it worth it? If my official one broke after 2 months should I buy another one? Also is it maybe to do with my phone and not the chargers? Please help someone! Also if I bought an apple one do they do return policy's or anything? Anyone?

"Is it worth it?"

You've probably spent more on avoiding buying the official one by purchasing the cheap ones. Maybe take it easy on the chargers, seems like all of them breaking points to user error.

I have an iPhone 5. My charger cord broke and Apple replaced it for free. I just sat up an appointment at the local store and went in.

I think that the official charger is definitely best. Some cheap knockoffs have been known to damage the phones.

I think that you would be better off if you did by an official charger because sometimes bigger companies will not sell how to build chargers to other companies and may even go as far as making the cheaper ones mess with your phone. When it comes to chargers you always want to buy official or another large company that maybe would know. What i would do is buy another official charger (when the you have breaks) and if that one breaks call Apple support and tell them your problem and I'm sure they will be more than willing to work with you.
