Since 2006, Apple has been using a magnetic plug called MagSafe on the adapters outside of its notebooks, inspired by the safety cables of electric rice cookers in Japan. However, it is not only the hand connector that is patented by Ma: even the overall design and fittings of the power brick have been registered in the name of Apple since 2003. You can imagine how much a company wanting to profit from it can get into trouble
Or rather, you need not even imagine: you can remember a lawsuit opened in November or just look at a new lawsuit started against three companies that sold MagSafe clones, the Brilliant Store, Sunvalleytek International (whose products are illustrated above) and Hootoo.
It is interesting to note that Sunvalleytek sells, through usadapters, both “oringinal” and cloned adapters. Also note that the connector shown above and on the left has a plastic and non-metal body, like the new original MagSafes.
Here is a recommendation: Apple adapters are not exactly perfect (but it has at least improved their design and even promoted exchanges, all in compliance), just that this is not a reason to give chance to chance by buying a product from doubtful origin. With electrical components, better not to risk it.
