My macbook pro power adaptor getting heated

我刚刚尝试了一下，我的电源适配器也好热！但是不至于融化的温度，可以尝试换一个吧。

I just have a try, I find my power adapter is very hot! But it is not the melting temperature.U can try to change another.

You have to replace the Power adapter.

You can buy a proper Power adapter from Apple store.

Is that the charger that came with the MBP?
