AC ADAPTATER

AC ADAPTATER is the sort of product name that only makes sense once the shape of the device is in front of you: a mains adapter for supplying power to another item. By our assessment, the strength is obvious in the category itself, because adapters solve a very concrete job and usually sit quietly in the background once the plug and output match. The weakness is also obvious from the name, which tells you almost nothing about voltage, current, connector type, or what equipment it belongs with. In practice this kind of thing is all about checking the fit and living with a small lump of plastic and cable near the socket. It is not a glamorous device, and it does not try to be one. The ceiling is compatibility, and without the rest of the specs it stays a vague power accessory.
