[DakotaDella]

According to national regulations, the minimum filling capacity of a vehicle-mounted fire extinguisher is one kilogram. As a car owner, when purchasing a vehicle-mounted fire extinguisher, you can choose one weighing between 1-3 kilograms. Below are the relevant instructions: How to choose: Common causes of car fires include electrical fires and fuel leakage fires. For electrical fires, a water-based mist extinguisher is more suitable; for fuel fires, a water-based foam extinguisher is preferable. Dry powder fire extinguishers have good versatility and a wide range of applications, making them suitable for both types of fires mentioned above. Usage specifications for dry powder fire extinguishers: Before use, the extinguisher should be fully inverted and shaken several times to ensure the dry powder inside is loosened. Pull out the safety pin, hold the nozzle with your hand (or support the bottom of the bottle with your hand if it is a tubeless extinguisher), and aim the nozzle at the base of the flame. Press the handle of the extinguisher firmly, and the dry powder will then be discharged from the nozzle.
