How to test the actual capacity of the multi-function car emergency start power?

As an automobile after-sales power supply, the automobile is a popular digital electronic product. With its versatility, it is favored and praised by consumers. It can be used as a digital product for automobile batteries, mobile phones, tablets, notebook computers, etc. One for power. It is an electronic product, and each power source is marked with the capacity of battery storage, but some bad merchants falsely report the battery capacity for the benefit, because the specificity of using this power supply for the car to start, including the power supply that falsely reports the battery capacity, It is very likely to bring danger to our use. So how do we test the actual capacity of the multi-function car emergency start power supply in daily use?mobile power plant

Multi-function car emergency start power

The steps to test the actual capacity of the multi-function vehicle emergency start power supply are as follows:

1. First, to test the actual capacity of a car emergency start power supply, we need to clarify and record the marked capacity of the power supply. This data is usually written in the outer casing of the power supply or in the manual;

2. The power of the emergency start power supply of the multifunctional vehicle is used up, and then charged until it is full. Since it is the starting power of the car, we still have to find a car to test, use the fully charged car emergency start power to test the number of car starts; if the conditions do not allow, of course, we can also use the phone to test the power supply in the case of the phone is dead How many times can you be charged? Although the method is more cumbersome, it is the easiest way to achieve the most reliable power supply capacity without other professional tools;

3. After completing the second step, we will use the mobile phone as an example to calculate according to the formula of the power supply capacity = mobile phone battery capacity × full number of times / 85% / 75%. In general, the conversion rate of the mobile phone battery we use is between 80% and 90%, while the conversion rate of the emergency power supply for the car is between 70% and 80%, so we compromise 75%. The conversion rate is calculated so that the authenticity of the emergency power supply capacity of the car can be known.

The above is the test method for the actual capacity of the multi-function vehicle emergency start power supply, but in addition to the above test methods, we have to look at the quality, performance and performance of the power supply. Therefore, in the process of charging, the specific implementation of the power will reduce the conversion rate of the power supply as the circuit board heats up during the charging process. In addition, we must also remind consumers to buy a car emergency start power must choose a regular brand, large manufacturers.
