The voltage of a dash cam is generally 5 volts, while the output voltage of all ports in a car is 12 volts DC. If a 5-volt dash cam is connected to a 12-volt power supply, it may burn out the dash cam. However, under normal circumstances, a dash cam can be used with a voltage reducer cable or the cigarette lighter port. Both the voltage reducer cable and the cigarette lighter port have voltage conversion functions. Therefore, connecting a 5-volt dash cam to a 12-volt power supply via the cigarette lighter port or using a voltage reducer cable will allow it to function normally without any issues.

Here are some precautions regarding car modifications: Car modifications must strictly comply with national laws and regulations, which clearly outline the requirements for modifying the appearance and performance parts of a vehicle. Generally, car owners can replace front and rear bumpers and grilles, but the size of these parts must not exceed the original dimensions.

What are the differences between domestically produced Mercedes-Benz and imported Mercedes-Benz?

Domestically produced Mercedes-Benz and imported Mercedes-Benz differ in terms of price, configuration, and dimensions. Here is a detailed introduction to the differences between domestically produced Mercedes-Benz and imported Mercedes-Benz: 1. Price: Imported models are subject to tariffs, value-added taxes, and various other taxes, so their prices are generally higher than domestically produced models. 2. Configuration: Many components of domestically produced Mercedes-Benz are manufactured by domestic OEMs. For example, the wheel hubs are produced by Zhejiang Jinfei Machinery Group. Although the sources of these parts are different and there may be no obvious visual differences, there is a noticeable difference in quality during actual use. To some extent, China's specialization level and technical expertise still lag behind those of foreign countries. 3. Maintenance: Maintenance for imported cars is more expensive. According to the "Auto Parts Price Ratio Research Report" released by the China Insurance Association and the China Automobile Maintenance Industry Association, the parts-to-price ratio for the Beijing Mercedes-Benz C-Class is 670%, while the imported C-Class can reach as high as 1200%.
