Recently, many users have reported some problems about the charging of the car's emergency start-up power supply. The biggest problem is that the car's start-up power supply cannot be charged. What's the use of the car's starting power if it can't charge? Useless! The slow charging of the car's starting power is barely acceptable. If it cannot be charged, then it is largely due to the power output restrictions set by various manufacturers. So how to analyze and solve these problems, JHC gives the following points:


1. Check whether the data cable matches the mobile phone or digital product

If it does not match, you can use the original data cable of the mobile phone or the digital product itself to link with the startup power supply, so that the adaptability will be better.

2. Check whether there is any problem with the quality of the adapter

If there is a quality problem, you can find the manufacturer to replace the adapter during the warranty period. If it exceeds, buy another adapter of the same type, or use the data cable that comes with the mobile phone or digital product to charge.

3. See if the double cable is broken

Similarly, if it is damaged during the warranty period, you can ask the manufacturer to replace it. If the warranty period is exceeded, buy an identical double-pull cable, or use the data cable that comes with the mobile phone or digital product itself to charge.

4.The adapter does not match the double cable

This problem is generally rare from regular manufacturers. If you encounter it, you can directly find the manufacturer to return or replace the product, or use the original data cable that comes with your mobile phone or digital product to charge.

5. Check whether the contact between the car starting power supply and the double-pull interface is firm

If the contact between the startup power supply and the double-pull cable interface is not firm, it may be that the USB interface on the startup power supply has been loosely inserted and unplugged many times during use. It can be returned to the factory for repair during the warranty period. .

6. The voltage of the starting power supply of the car may be too low

The voltage of the starting power supply of the car is generally around 5V, which is not related to the general mobile devices, but the voltage requirements of some mobile phones remain unchanged and can only be charged at a few volts. Adjust the voltage volts of the car's starting power supply.


Under normal circumstances, these low-level problems will not occur in the car starting power supply produced by regular manufacturers. It is recommended that you buy certified and guaranteed regular automobile starting power supply manufacturers.
