The length of the cable supplied with or included with the charger. For wireless models, the length of the power cable of the charger itself is indicated here, for wired models, the length of the cord for charging gadgets
Anyway, a longer cable gives more freedom of movement, but it creates inconvenience for short distances. Also note that charging is supposed to be used in the immediate vicinity of sockets, so wires longer than 2 m are practically not found among such devices. A length of
more than 1.5 m is considered significant, from 1 to 1.5 m — medium, from 0.5 to 1 m — small, and in some models there are wires shorter than 0.5 m.
Whether or not
a power adapter is included with the charger.
This feature is relevant primarily for wireless models, including the ones for cars(see "Type"). Such devices usually consist of three parts: the charger itself with a platform/stand/latch, a charger power cable and an adapter for connecting the wire to a power outlet or cigarette lighter. If the presence of an adapter is initially indicated in the specifications, then the charger is supplied in a complete set; it is these models that you should pay attention to if you want to use the device right out of the box, without the hassle of finding additional accessories.
Also, this feature can be indicated for individual car chargers of the traditional, wired type. This usually means that the device is similar in layout to wireless models: main unit, power cord and cigarette lighter adapter. This design allows you to use the charger at some distance from the dashboard of the car — for example, take it to the back seat, giving passengers the opportunity to charge their phones. In this case, the adapter can have its own charging outputs (usually USB) and can be used separately from the main unit.
