Car emergency start power loss when charging it?

Car emergency start-up power loss when charging it? This problem may be that many people use automotive emergency start-up power have a problem in my heart, the answer to this question Yes. For example, we use 4000mAh capacity car emergency start-up power to charge the phone, its power can not all reach the cell phone battery, because the use of electronic products in the process of battery loss is a normal phenomenon , So the car emergency start power battery loss in the charging process is inevitable, it mainly exists in the following aspects of the loss:

Car emergency start power loss when charging it?

1, power loss.

Auto Emergency Start Power When charging a mobile phone, it charges more than just the battery, it also needs to power the other parts of the phone, so this is one of the losses that a car's emergency start-up power source charges the phone.

2, voltage loss.

In general, the automotive emergency start power battery is the use of maintenance-free lead-acid batteries and lithium polymer battery, which lithium polymer battery discharge voltage is not changed, the safe discharge range is 4.2 V-2.7V, so the greater the range of discharge, the loss of its power will be increased accordingly.

3, resistance loss.

We should all know that the car emergency start-up power supply to the phone, are connected through the circuit board and wire. Therefore, there is a conductor in the connection between them, and in the case of a conductor, there is resistance. The main physical property of resistance is the conversion of electric energy into thermal energy. Therefore, the car emergency start the power supply to the phone in the process of charging, the conductor will have heat generated, the heat generated will be quite depleted car emergency start power supply.mobile power plant

4, circuit conversion loss.

Car emergency start power to charge the phone, there will be fever phenomenon. 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 switching loss is also a loss of automotive emergency start power supply on the one hand.

The four aspects described above are the most important aspects of automotive emergency start-up power loss in charging, then how should we reduce these losses? We can be in the car emergency start-up power charging process, it is best to do Constant voltage and constant current, as constant voltage and constant current can be output voltage and current stability of the output, so that the car emergency start power supply loss reduction in the standard range, so that you can properly reduce the car emergency start power supply Charged when the loss generated.
