Most so-called universal plug adapters aren’t. Universal, that is. They are capable of converting between the most common outlets like the C-type (used in much of Europe) and the A-type (North America and Japan). But your typical plug adapter can’t conform to the M-type of plug (southern Africa) or L-type (northern Africa and the Middle East). Some even have a hard time with the “sunken” plugs used in Europe, like the J-type (common in Switzerland) or F-Type (found in Germany).
The APC is one of the few universal plug adapters that can handle every residential outlet type on the planet. And it is by far the smallest and most lightweight of those that can. The APC is so efficient because it consists of two parts, each of which can be twisted, turned and attached together in a multitude of ways such that its users can be forgiven for thinking that they are playing with a transformer toy. The design is unusual, but it works. Always. Making the APC adapter one of Spot Cool Stuff’s must-pack items for any international trip.
