Starting current
Rated starting current of the starter or booster (see "Type").
In this case, we mean the current that the device in the engine start mode can produce for a relatively long time (at least 30 s, or even more). This indicator must not be lower than the rated starting current consumed by the starter of the car — otherwise the device simply does not have enough power to effectively scroll the starter and start the engine. Information about the required starting current can be clarified by the documentation for the machine, or by the characteristics of the battery that is used in it as standard. For most passenger cars, this figure lies in the range from
200 to 400 A ;
less powerful starting devices are intended mainly for motorcycles and other similar vehicles, and more powerful ones for buses, trucks and other heavy equipment, among such “starters” there are models for
400 – 600 A and even
more.
Peak output current
Peak inrush current of the starter or booster (see "Type").
Peak current is the highest current that the device can deliver without problems for a short time (1 – 2 s). This current is noticeably higher than the nominal starting current (see above), which corresponds to the operation of a car starter: starting to spin up, the starter consumes a very high current, which, however, decreases almost immediately.
The peak inrush current of the ROM or booster must not be less than the peak inrush current of the starter. You can specify the latter according to the documentation for the car, or according to the characteristics of a regularly used car battery.
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 starting devices, such outputs are also widely used for charging gadgets. These ports are characterized by low power, which does not exceed 15 W (although this is quite enough to charge gadgets) and a stable current strength, which is constant throughout the charging process.
USB C
The presence of a
USB C connector in the design of the ROM for recharging gadgets with the appropriate cable. Due to the popularization of this port, such a solution does not look unusual, but rather helps to keep up with the times.
In addition to the number of such ports, the voltage and current on which the port operates, as well as the maximum charging power, can be indicated.
- The strength of the current. The maximum current output through the USB type C connector to a charging device. Note that different ports of the charging station can output different current (for example, 1.5 A and 2.1 A). In this case, the highest current 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 corresponding power must be supported by the device being charged - otherwise the speed of the process will be limited by the characteristics of the gadget.
