"One of the annoying things about owning a laptop (there are a few) is that often your adapter will get damaged from constant packing and unpacking. The simple act of wrapping up the cord can damage the wires over time. This has led to more than a few useless adapters sitting in the drawer and a long wait while a new one arrives (not to mention the extra cost of buying a new one).
Even buying a third party adapter can be a pain. Many of these are bulky and fail faster than the original one. So what are you to do? Well, Cooler Master has a good answer for many of you out there. This is their line of USNA adapters; USNA standing for Ultra Slim Notebook Adapter."
