Final comments: The Aywun Megapower Elite 550 turned out to be a disappointment. It is unable to deliver the rated 550W and isn’t particularly efficient, so it’s a wonder that Aywun managed to get this product certified by Ecova. It also doesn’t have a very good cable configuration, and the build quality was very average. Additionally, there are better products on the market for a similar price. Therefore, this is not a recommended product.
Score: 5/10
