The minimum filling capacity is one kilogram. Here is the relevant information: 1. The minimum filling capacity is one kilogram. Some car owners purchase fire extinguishers weighing five hundred grams, which is half a kilogram, below the national standard requirements and therefore non-compliant. When purchasing a car fire extinguisher, it is essential to choose one with a capacity of two kilograms or more, produced by a reputable manufacturer, to more effectively ensure the safety of the car owner's property. 2. The optimal time for self-rescue during a vehicle fire is within 1 to 3 minutes after the vehicle starts emitting smoke, which is the initial stage of the fire. The fire development stage occurs between 3 to 5 minutes. Beyond 5 minutes, it enters the intense burning stage, where it becomes nearly impossible to control the fire independently, and waiting for the fire department's rescue is necessary.

I've been driving for over a decade, and my car's fire extinguisher is 2kg, mainly because this size is commonly used for sedans, with 1kg or 2kg being the most common. Once at a highway rest stop, I saw a car emitting smoke, and the owner's 1kg fire extinguisher wasn't enough—it took the help of passersby to put out the fire. Since then, I've always emphasized that at least 2kg is safer; don't skimp on cost with a smaller capacity. A slightly larger extinguisher can cover more fire sources, like giving you a few extra seconds to control an engine fire. I also recommend the dry powder type, which has a three-year validity period, and I keep it in the driver's side door pocket for easy access. Regular checks are crucial too—if the pressure gauge turns red, it's time to replace it. In short, the size of a car fire extinguisher varies by vehicle—1-2kg for regular cars, 2-4kg for larger vehicles—but 2kg is the golden choice, offering the best balance of safety and cost-effectiveness.

As a daily driver, I always keep a 2kg fire extinguisher in my car. Common sizes are 1kg and 2kg, and I personally think 2kg is more reliable because 1kg might be too small to control the fire. Some regulations require a minimum of 1kg, but after witnessing several accidents, I've found that fires spread quickly, and a larger extinguisher is more effective. I place it in the armrest box or under the front seat, avoiding deep storage in the trunk. When using it, don't panic from the smoke—stay calm and aim at the base of the fire. I recommend buying an ABC-type dry powder extinguisher, which can handle both electrical and oil fires, with a lifespan of about three years. It's not expensive—around 100 yuan for 2kg—much cheaper than car repairs. Safety awareness is crucial; this isn’t a waste of space.

From a technical perspective, car fire extinguishers typically offer capacities ranging from 1kg to 4kg. Compact cars usually opt for 1kg or 2kg models, while larger SUVs may require 2-4kg for better safety. Personally, I recommend starting with a 2kg extinguisher as it strikes a balance between size and usability. Key factors influencing the choice include vehicle size and driving habits - frequent off-road travelers should consider larger capacities. Dry powder types are preferable as they can handle various fire causes. Ensure it's mounted within easy reach near the driver's seat. Remember these have a 3-year validity period - regular checks prevent expiration. This design significantly reduces driving risks.
