Charging areas
Number of wireless zones in the charging design.
The basic option is
1 zone, allowing you to charge one device at a time. To charge several gadgets overnight, models are available for
2 zones,
3 zones and even
≥4 zones. At the same time, at least one zone is made large - it is intended for a smartphone. Other zones can be made in the same caliber as the main one or have smaller sizes, and in some cases they are suspended structures for wrist gadgets (see “Watch charging zone”). Auxiliary zones are usually used to charge another smartphone, a case with headphones, smart watches and other portable devices.
Smartwatch charging area
Area for wireless
charging of smart watches or other wrist gadgets. In this context, it can mean either a regular flat platform or a specialized structure (usually in the form of a kind of “hanger”). Such “suspensions” are often more convenient than platforms, and some smart watches can only be charged in this way. On the other hand, such additional equipment is not always necessary , so most wireless chargers are produced
without a separate zone for smart watches.
Power (with 1 device)
The maximum power that the charger is capable of delivering to one rechargeable gadget (for models with 1 connector or with 1 wireless platform — the actual charging power). We emphasize that for wireless devices, it is the power in the wireless format that is indicated here (even if the design has a USB port with a higher power). Wired chargers usually list the USB power with the highest charging current or with support of the most powerful fast charging technology.
The smallest value of this metric nowadays is actually
5 W. Other popular options include
10W,
12W,
15W, and the most powerful models have
18W or more
to charge laptops(up to
100W).
Higher output power allows you to speed up the charging process; and in the case of wireless devices, a value of more than 10 watts already allows us to talk about the presence of fast charging. At the same time, a number of nuances are associated with this parameter. Firstly, not only the charger, but also the gadget being charged should support the appropriate power — otherwise the speed of the process will be limited by the specs of the gadget. Secondly, in order to use the full capabilities of the charger, it may be necessary to support not only the appropriate charging power, but also a
...certain fast charging technology (see "Fast charging"). Thirdly, in a charger with several charging connectors, the maximum power per device can only be achieved if the other ports are not used.Cable length
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.
