Nic:
Hello, I would like to expand on what Zerge replied with. The most common type of Fire Extinguisher people place in their cars (pickups and SUV?s) is a 2 ? pound (about 1.14 Kg) Multipurpose ABC Dry Chemical extinguisher. You can purchase these style extinguisher in most hardware stores and auto-parts stores, then you can ?mount? one in your car. As pointed out a loose extinguisher can become a projectile in an auto accident. You should carefully evaluate what type of need you have in the house and in the car. Once you have that done you may purchase an extinguisher.

Most extinguishers are rated according to the National Fire Protection Association (NFPA) guidelines and also the Underwriters Laboratory (UL) rating system. These are the suggested ?minimum? standard for each extinguisher. These companies place a rating for temperatures between ?65?F to +120?F (- 54?C to +50?C) provided you have an aluminum canister. I am not aware of temp ratings for the plastic containers. Therefore, I do not recommend the plastic ones.

Some extinguisher basics

Learn how to use one, use the PASS method, that is Pull the pin, aim the extinguisher, squeeze the trigger and sweep from side to side at the base. Never try to blanket the fire with the extinguisher. You may find you only ?blow? the fire vs. fighting it.
Teach your family how to use one. General peace of mind. <img src="/images/graemlins/smile.gif" alt="" />
Extinguishers will vary in discharge rates from as little as 10 seconds to about 2 minutes. Beyond this and you will need to call the fire department.
Before you attempt to fight the fire (home, or auto) make sure everyone inside is safe.
Check them monthly, make sure the nozzle is clean and free of dirt, grime and oils.
Check the gauge, make sure it is still showing the extinguisher is charged and the gauge is not broken.
If ABC dry chemical, shake the canister you should feel a ?fluid? slide motion. A more solid thump and the extinguishing agent has solidified (remember it is a powder) and you will need it serviced.
Have yearly inspections by a professional. This can be costly, but well worth it. The professional will check seals, powder, clean and hydrotest to make sure the extinguisher is going to function when discharged.
Make sure you purchase a metal vs. plastic canister. Plastics cannot be hydrotested and will need full replacement every 12 years.

I keep one in my pickup at all times and have never had any temperature related problems.

Take care,
