What is the purpose of the 12V socket in the trunk?
2 Answers
The 12V power socket in the car trunk can be used to connect 12V electrical appliances such as car refrigerators, car vacuum cleaners, and projectors. Here is some knowledge about car batteries: 1. Introduction: The lifespan of a car battery depends not only on its structure and quality but also on its usage and maintenance. Generally, the lifespan of a car battery is about 2 years, but with proper maintenance, it can last 3-4 years. Many car owners have misconceptions about battery maintenance, leading to early battery damage. 2. Checking for damage: Check whether the charger is damaged and whether the charging parameters meet the requirements: the initial charging current should reach 1.6-2.5A per cell; the maximum charging voltage should reach 14.8-14.9V per cell, the charging to float charging transition current should reach 0.3-0.4A per cell, and the float charging voltage should reach 14.0-14.4V per cell.
That 12V outlet in the trunk is incredibly practical! After driving for over a decade, I've relied on it to solve so many hassles. When camping, I just plug in a mini fridge in the trunk to keep food fresh throughout the trip—especially useful in summer heat to prevent spoilage. It’s also great for charging phones and laptops during long drives, eliminating the hassle of finding power outlets. Once, when my tire pressure was unstable, I even used the cigarette lighter socket to quickly inflate the tire with a portable pump by the roadside. But be cautious not to plug in high-power devices like car heaters or heavy-duty vacuums—exceeding 120W can blow a fuse or even damage the electrical system. This trunk design makes travel more worry-free, saving both money and effort.
