In the category of automotive electronics, in addition to driving recorders, smart rearview mirrors, driving monitoring and shooting products, there is also a category that is specifically produced for powering equipment used in the car. This is USB car charger.
With the upgrade of wireless networks, there are more and more mobile devices. The network has been upgraded from 4G to 5G. The network is getting more and more smooth. Mobile devices such as smartphones also transmit more data, but battery life has also become a problem for mobile devices.
Therefore, it is ideal to be able to charge anywhere. There is a power bank in the bag and a USB car charger in the car, which realizes a seamless battery life connection everywhere. People no longer have to worry about the battery life of mobile devices in the car.
In fact, most of the USB interface in the car limits the interface flow, which also causes the interface current to be divided into 5V/0.5A and 5V/1A. At this time, if the wrong interface is selected, it will not only easily cause the phone to become hot, but also cause a longer charging time. It will eventually seriously affect the battery life of the mobile phone.
Use car USB to charge your phone while navigating, the more you charge, the less power will be!
Most of the USB ports in the car are designed to transmit data. Although it shows it is charging after being connected, the current is only about 0.5A. When you are listening to a song or navigating with a mobile phone, the power consumed per unit time is actually greater than the power charged. Therefore, there will be a situation where the power is not rising but falling.
1. Know the output voltage of the car cigarette lighter
Generally, general-purpose USB car chargers (12V) are mostly suitable for cars. If there are other models, you need to select the corresponding voltage standard. Of course, there are many USB car chargers that can meet the 12V-24V standard, which is applicable to all models. In a word, it is most important to choose the right one.
2. Does the USB car charger have an automatic protection function?
A good USB car charger should have protection functions such as overvoltage, overcurrent, overheating, and short circuit. The outer shell is preferably made of ABS flame-retardant environmentally friendly materials. For patients with obsessive-compulsive disorder, a smooth and clean surface that does not leave fingerprints is simply perfect.
