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.
Sockets (230 V)
Total number of outlets with output voltage. This is, in fact, the number of devices that can be simultaneously connected to the charging station without the use of splitters, extension cords and carriers. Accordingly, weaker charging stations have
one or
two sockets in their submission.
Powerful charging stations already have three or
more sockets “on board”.
USB A (quick charge)
Full size
USB A ports with fast charging support. It allows you to charge your smartphone, tablet or other connected device much faster. The charging process takes place at increased power, and the current and voltage at each stage are regulated in such a way as to remain within the optimal values. However, it should be borne in mind that in our time there are many fast charging technologies and not all of them are compatible with each other.
- The strength of the current. The parameters of the current issued through the USB A fast charging connectors. Note that different voltage and current parameters can be output to different ports of the charging station. This item specifies the current values at a certain voltage (for example, 5 V / 3 A, 9 V / 2 A, 12 V / 1.5 A).
— Power. The maximum power in watts (W) that the charging station is capable of delivering through the USB A fast charging connector to one charging device. High output power 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.
USB 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.
Anderson port
A large two-pole connector for connecting batteries, chargers and all kinds of equipment where reliable contact is required for the sake of ensuring stable operation of the equipment.
Anderson Port is resistant to moisture changes, can be used both for indoor and outdoor mechanisms. Thanks to identical mating parts, a pair is formed by two identical connectors, which are rotated 180 ° relative to each other. Most often, Anderson port is used in mobile homes on wheels.
Charging cycles
The number of charge-discharge cycles that the battery can withstand without significant loss of performance.
In the process of operation, the batteries wear out, which causes their performance to suffer (in the first place, the capacity decreases). Battery life is usually measured in charge-discharge cycles. However, models with the same declared resource are not always equally durable in practice. Different manufacturers may interpret “significant loss of performance” in different ways: for example, one brand indicates the resource up to a 20% decrease in capacity (DOD > 80%), another - up to a 60% decrease (DOD > 40%) Behind the abbreviation DOD worth decoding Depth of Discharge, i.e. discharge depth. Therefore, when choosing, it makes sense to focus not only on pure numbers, but also on other sources - test results, reviews, etc. Also note that battery life can be noticeably reduced if the operating conditions are violated (for example, in case of overheating or hypothermia).
Charging time (socket) ≈
Time to charge the portable power station from a fully discharged state to 100% charge when using the power adapter from a household outlet. This refers to the original battery and standard charger.
Charging time (solar panel) ≈
Time spent on a full charge when using the original panel in bright sunlight. In cloudy weather, the charging time of the device from the solar panel can be strikingly different downwards.
Charging power (socket)
The power at which, in normal mode, the portable power station is charged from a household outlet when using the original power supply.
