Recently, some netizens have reported that Tesla's newly delivered Model 3 and Model Y models are not equipped with USB interfaces, and only holes are reserved. Therefore, users cannot connect external devices such as USB sticks.
In view of the above situation, for the owner of the mobile phone can not be charged through the USB interface, it is almost crazy. That being said, most car owners are now using these interfaces to charge electronic devices such as mobile phones, and will install car chargers on the interfaces, but 80% of them are not using the right ones.
Usb interface distribution in the car
The USB interface on the car is mainly distributed in the multimedia screen, the rearview mirror in the car, the front central armrest box and the rear exhaust outlet, in addition, the cigarette lighter on the car can also be transformed into a USB interface that can provide power for electronic devices with the help of "car charger".
All interfaces can charge the phone? So naïve!
Although the usb interface position of different models is different, the functions are similar:
1. The interface at the multimedia screen is mainly used for audio data transmission;
2. The rearview mirror in the car is to provide power to the driving recorder;
3. The interface between the handrail box and the rear exhaust air outlet is used to charge mobile phones and other devices.
Among them, the USB interface at the multimedia screen is the most likely to be misused by car owners. After all, many car owners have such a concept, all USB interfaces can be used to charge mobile phones.
In fact, the USB interface current at the multimedia screen is generally only 5V/ 0.5A, which can only be used for playing music on a U disk, if used to charge the mobile phone, it will not only hurt the mobile phone, long-term use may also damage the vehicle's battery.
In addition, the interface at the rearview mirror in the car is also used incorrectly by many car owners. Although it can indeed be used to charge electronic devices, it is not recommended to use it, especially during driving, once it affects the driving line of sight, the consequence may be an accident.
In addition to misuse, what else should I pay attention to when using the interface?
1. Do not unplug when reading, writing or saving data on the U disk, so as not to cause damage;
2. Whether it is plugged in the U disk or the power cord, can not be overexerted, if it can not be inserted, please try to change the insertion angle;
3. All interfaces are not used for a long time, please unplug the USB flash drive or power cord to avoid accelerated aging;
4. When the vehicle is on a bumpy road, there may be disconnection, at which time it should be reseated;
5. Please keep the interface clean and tidy, if there is rust, water stains, fine garbage or other foreign objects in the interface, it will cause the connection to not be connected;
6. The maximum power of the on-board electrical appliances shall not exceed 120W, otherwise it may damage the automobile circuits or electrical equipment;
7. Since the output voltage and current of the USB interface of each model are different, please read the instructions for use of the car carefully before use.
Precautions for external equipment such as car charging
For some external "car chargers", it is more necessary to pay more attention, because it is likely to cause a fire if you are not careful.
For example, Before Mr. Liu in Nanjing, Jiangsu Province, took his wife and children out to play, just parked the car and found that there was smoke coming out of the car, and then the car burned. After testing, the cause of the fire was caused by an inferior "car charger". So, these precautions you need to know too!
1. You cannot choose "three no" or "cottage" products, please choose a regular manufacturer to produce when purchasing, and with overload protection function.
2. Select a product with an output current of 1A or more. Charging a mobile phone, for example, not only can not provide normal charging, but also the power continues to drop.
3. If during use, the external equipment such as the car charger makes an abnormal noise or has poor contact, be sure to go to the 4S shop or a nearby repair shop for safety testing.
In general, external devices such as USB interfaces and car chargers in the car can bring a lot of convenience to the owner, but if you do not pay attention to the details, it is easy to have problems. Therefore, for the safety of people and vehicles, everyone must standardize the use.
