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.
UPS function
Charging stations with
UPS function switch consumers to backup power from their own battery, acting as an uninterruptible power supply. In comparison with full-fledged UPSs, switching does not occur instantly, but with a certain delay (about 10-30 ms). To use this function correctly, you must first study the instructions for the charging station, which often describes the correct procedure for connecting the intended consumer devices.
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.
DC output
The presence of a DC connector (or several such outputs) in the device to power external gadgets with direct current. The standard DC jack is round and has a pin in the center. However, its dimensions may differ in depth and diameter. The voltage output to the
DC output may be different. The most popular options are 18 - 20 V for powering laptops, 12 V for various specialized devices and automotive electrical accessories.
From USB type C port
The ability to replenish energy reserves in the battery cells of the charging station via
the USB type C connector. This port itself is small in size and has a convenient double-sided design, thanks to which the plug can be inserted in either direction. However, in charging stations it does not always work as an input interface.
DC input
DC connector for a distinctive round plug (like those used in many laptops) used to recharge the battery of the device. Note that
DC- in plugs may have different sizes, and chargers with such plugs may have different operating voltages. In practice, this leads to the fact that finding a suitable charger for a portable station is not easy, you need to be especially careful when searching.
Input port XT60
Power connector with two round connectors, used to replenish energy reserves in the battery cells of the charging station. For the most part,
the input port of the XT60 is for charging the device from solar panels using the appropriate cable.
Add. ports
Additional input connectors provided in the design of the charging station in addition to those described above.
