Built-in battery capacity
Capacity of the own battery provided in the design of the starter-charger.
As a rule, boosters and launchers with a power bank function are equipped with their own batteries (see “Type”). The main purpose of such a battery from the point of view of helping to “light up” is to provide the power necessary to start the engine. However, in some models the battery is responsible for other functions, such as the built-in compressor or flashlight. The larger the battery capacity, the longer the device can operate, and the more tasks it can perform on a single charge.
In starting devices with the powerbank function, this parameter is also given to estimate how much energy the battery can accumulate and then transfer to connected gadgets. It is important to consider that there is a nominal (declared) and real capacity - the latter is always less, because it takes into account the inevitable losses during energy conversion. Typically the difference is from 30 to 40%, i.e. a model with a conventional battery capacity of 10,000 mAh will not fully charge a smartphone with a 3,000 mAh battery three times, but at best will provide two power cycles, because in practice its working capacity is about 6,000 mAh. Therefore, it is not entirely correct to compare the mAh values of your gadget’s battery with the nominal capacity of the built-in battery - you should definitely take into account that the real capacity is always less than the “rated” one.
USB type 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.
