Does a car emergency start power supply lose power while charging?

Will the DOCA car's emergency start-up power supply lose power while charging? This problem may be a problem for many users who use the car's emergency start-up power supply. The answer to this question is yes. For example, when we use a 4000mAh car emergency starting power supply to charge a mobile phone, its power cannot all reach the cell phone's battery, because the loss of the battery during the use of the electronic product is a normal phenomenon. Therefore, the loss of the car's emergency starting power supply battery during charging is unavoidable. It mainly has the following losses:

Does a car emergency start power supply lose power while charging?

1, power loss.

When the car emergency starting power source charges the mobile phone, not only the battery is charged, but also it needs to supply power to other parts of the mobile phone. Therefore, this is also one of the losses caused by the car's emergency starting power source charging the mobile phone.power bank plant

2, voltage loss.

In general, its emergency power supply batteries for automobiles use maintenance-free lead-acid storage batteries and lithium polymer batteries. The discharge voltage of lithium polymer batteries does not change, and its safe discharge range is 4.2. Between V-2.7V, the larger the discharge range, the greater its power loss.

3, resistance loss.

Everyone should know that when the car's emergency starting power source charges the phone, it is connected through the circuit board and the wire. Therefore, there is a conductor between their connections, and all conductors have a resistance. The main physical property of their resistance is to convert electrical energy into heat energy. Therefore, during the process of charging the mobile phone by the emergency power supply of the car, there will be heat generated in the conductor, and the amount of heat generated will consume a considerable amount of power of the car's emergency starting power supply.

4, circuit conversion loss.

When the car's emergency starting power source charges the mobile phone, it will generate heat. Therefore, according to the law of conservation of energy, the heat emitted by the product itself is actually the energy of the built-in battery, so the circuit conversion loss is also one of the aspects that deplete the power of the car's emergency start power supply.

The four aspects mentioned above are the most important aspects of the car's emergency start-up power source when it is charged. How can we reduce these losses? We can do this in the charging process of car emergency starting power supply. Constant voltage and constant current, because the constant voltage and constant current can effectively output the stability of voltage and current, so that the loss of the car emergency starting power supply when charging is reduced within the standard range, so that the emergency starting power supply of the automobile can be appropriately reduced. Loss caused by charging.
