Rated power
Power that a device can consistently produce for an indefinitely long time without any unpleasant consequences. For normal operation of the charging station, the rated power must be at least 15 - 20% higher than the total power of all devices simultaneously connected to it.
Peak power
Some electrical appliances (in particular, units with electric motors - refrigerators, air conditioners, etc.) consume significantly more energy at startup than after reaching the operating mode. For such a load, the peak power of the charging station must be taken into account - its indicator must be higher than the starting power of the load.
USB type C
USB type C ports are smaller than classic USBs, and they also have a convenient reversible design that allows you to connect the plug in either direction.
USB type C was originally designed to be able to implement various advanced features: increased power supply, fast charging technologies, etc.
Since the port is relatively new and quite powerful (there are
USB type C with a power of 60 W and even
100 W), the total number of such connectors is often limited to
1 port, less often
two).
- The strength of the power. The maximum power output through the USB type C connector to a charging device. Note that different ports of the charging station can output different power (for example, 1.5 A and 2.1 A). In this case, the highest power strength is usually indicated.
— Power. The maximum power in watts (W) that the charging station is capable of delivering to one rechargeable gadget. The high output power of the USB type C port allows you to speed up the charging process. However, the appropriate power must be supported by the device being charged - otherwise the speed of the process will be limited by the characteristics of the gadget.
Add. ports
Additional input connectors provided in the design of the charging station in addition to those described above.
PSU
— External. Outdoor placement of the power supply requires additional space. However, most blocks of this type are quite compact in size and are equipped with “plugs” for sockets right on the case - in other words, the block is installed on a socket, and from there the wire stretches to the charging station. There are also external power supplies on the cable. Considering that you only need to connect the adapter while the device is charging, an external power supply is a very convenient solution.
- Internal. The built-in power supply does not take up space outside the charging station, however, it can increase the dimensions and weight of the device. The advantage of this arrangement is that the most common power wire goes from the housing to the socket, without additional equipment on it. At one end it is connected to the socket, the other end is connected to the input connector of the charging station.
