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
Full-size USB A connectors are popular in computer technology, they are standardly used in adapter chargers for 230 V household networks and 12 V auto sockets. In charging stations, such outlets are widely used for charging gadgets.
- The total number of such ports can be very diverse (
1 USB,
2 connectors,
3 ports and even
4), since it allows you to connect for charging, and in some cases for power, various low-power devices -
smartphones,
tablets,
power banks,
lamps, etc. .
- The strength of the power. The maximum power output through the USB A connector to the device being charged. 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
output power in watts (W) that the charging station is capable of delivering through the USB A connector to one charging device.
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.
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.
Connecting an additional battery
Ability
to connect an external battery to the charging station to increase the overall energy consumption and, as a result, extend the battery life. This connection is fast and convenient. On the other hand, the battery takes up extra space on the outside, making the whole structure more cumbersome.
Battery capacity
Nominal
battery capacity, in fact - the amount of energy that is supposed to be stored. The larger it is, the longer the battery life of the charging station will be, all other things being equal. On the other hand, this parameter also affects the dimensions, weight and price of the battery, despite the fact that an energy-intensive battery is not always required. By the indicator of capacity in watt-hours, you can compare batteries with each other.
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 + solar panel) ≈
The parameter allows you to estimate the approximate battery charging time in the mode of combined connection of a portable power station - from a power outlet and a solar panel overnight. This method of replenishing energy reserves allows you to speed up the charging process.
