What is the capacity of a car fire extinguisher?

For ordinary family cars, it is recommended to equip a small fire extinguisher, which is lightweight and easy to carry, around 2kg. Below is an introduction to fire extinguishers: Car fire extinguishers: Specifically designed for vehicle fire suppression, car fire extinguishers include two main types: non-storage pressure hanging ultra-fine dry powder automatic fire extinguishing devices and mini storage pressure hanging ultra-fine dry powder automatic fire extinguishing devices. Currently, most fire extinguishers used for vehicle fire protection are portable extinguishers. The main types of car fire extinguishers on the market include dry powder extinguishers, ultra-fine dry powder extinguishers, carbon dioxide extinguishers, and water-based extinguishers. Shelf life: Different extinguishers have varying expiration dates due to their materials. Generally, the validity period of a car fire extinguisher is two years. If there is no expiration mark, the pressure gauge's needle in the green zone serves as the indicator. When the needle on the pressure gauge of a car fire extinguisher points to the red zone, it indicates insufficient pressure, and the extinguisher must not be used at this time.
I think a car fire extinguisher should be at least 1 liter. Last time, the owner of the modification shop said that with today's complex wiring in new energy vehicles, he keeps two 2-liter cans in his own pickup. For regular gasoline cars, a 1-liter dry powder extinguisher is enough, but remember to shake it upside down in winter to prevent clumping when stored in the trunk. Once, my friend's car hood started smoking, and the newly bought 0.5-liter small can ran out after just two sprays—ended up smothering the fire with a blanket, which gave us a cold sweat. I recommend going straight for a water-based fire extinguisher; a 2-liter one can even be sprayed on yourself to escape.
