IPhone 5s charger not working anymore?

I got my iPhone 5s about a month ago. The charger was working fine for awhile and I kept it in good condition. Recently it started to stop and then start charging my phone and today is just stopped working altogether. Other chargers work on my phone though. Why did this charger just stop working and would Apple give me a new one for free?

9/10 Apple will not replace your chargers unless they went out by a defect on their part.

There are several off brand chargers you can buy but they have a higher hazard of causing a fire as they are not approved via Apple.

IPhone product support 1 year quality warrently. Since you got it a month ago, you can ask a new iPhone charger for totally free, i think.
There are many kinds of Charger for iPhone on some online store. You can buy one with good price and good quality.

They will exchange them every time I being in 3-4 chargers at a time if phones are under warranty they will exchange chargers for 12 months just went 2 months ago and going back today charger broke again
