This adapter does not fit the RT-AC66U dual band router. Very disapppointed.

No clue where the original one went, but this one just works!

This power adapter works really well on my computer.

Best adabter

It worked as expected.

As others have stated this does not even come close to fitting the ASUS RT-AC66U router. Do not buy it for that hardware!!!

Ordering the product was easy and well organized.The product itself was defective which did not help matters

Thank God it works.
