How to distinguish the quality of car emergency starting power

The DOCA emergency power supply for automobiles is a product that has been developing rapidly over the past few years. It can provide start-ups for automobiles and provide a source of supply for digital products such as mobile phones and notebooks. However, it is precisely because of the fierce sales of automotive emergency start-up power supplies. Currently, manufacturers of automotive emergency start-up power supplies on the market are springing up, and the quality of products produced by them is uneven. So how does a car emergency startup power differentiate between good and bad?

1, batteries.

The battery core is an indispensable part of the car's multi-functional emergency power supply. It can be said to be the core of the multifunctional emergency power supply for the entire vehicle. Therefore, its quality is a difference between the quality of our automotive emergency start-up power supply. We can judge its quality mainly through the aspects of capacity, working voltage, and charge and discharge cycle life.mobile power plant

2, security.

The car emergency starting power supply is an indispensable escort partner for those who have a car. Therefore, it is good or bad to distinguish the emergency starting power supply of a car. It is necessary to first look at the safety technology to achieve compliance. Because the level of safety is a very important criterion for distinguishing the quality of emergency power supply for a car, we can see if there is a reverse polarity protection, output short-circuit protection, over-voltage protection, over-current protection, etc. A number of global patent safety protection designs are designed to judge if the safety technology fails.

3, the circuit board.

Everyone should know that when charging the car for emergency power, it is usually connected through the circuit board and the wire. Therefore, the quality of the car determines the output quality of the car's multifunctional emergency power supply. Therefore, we must pay attention to the selection of its circuit board when distinguishing between the emergency power supply of the car. Only an excellent circuit board can give full play to the maximum performance of the car emergency starting power supply.

4, conversion efficiency.

In the automotive emergency starting power supply, its conversion efficiency is one of the more important criteria for judging whether the product conversion ability is good or bad, and the automobile emergency starting power supply with high conversion rate can provide users with longer battery life. At present, the conversion rate of domestic automotive emergency power supply is generally around 80~85%.

5, battery capacity.

Although the number of judging standards for the quality of emergency power supply for automobiles is not particularly large, it is also a selection criterion that distinguishes the quality of automotive starting power. The size of the battery capacity often determines the number of times the car is started and the longevity of the battery life. But this battery capacity does not mean that the bigger the better, but should look at the performance of various aspects of the product and then make the choice.

The core, safety, circuit board, conversion efficiency, and battery capacity of the car's emergency start-up power supply are the most important aspects in distinguishing the quality of the emergency power supply for a car. Of course, there may be some other factors, such as the design of the product.
