Not much problem, I was bought a UK leg adapter from taobao to replace the original asus adapter but the DC plug head got some problem. The head can plug to my router but problem is when I slightly move the router, the adapter cannot tightly lock on the DC socket of my router. My router keep power off and power on. So in the end, I was using back the original Asus adapter. The adapter is using China 2-pin leg. I was went down electrical shop to buy an universal adapter, Make sure is buy the good quality one, so you can plug the China 2-pin socket tightly on the universal adapter.

I am using the good quality one, so everything are attached tightly. Not much problem for me for the China socket.

Bought mine from this seller.
