Ever drive by a car parked on the shoulder of the road, smoke billowing from under its hood, and think, "Glad that's not me"? It's a pretty smart idea to take out a little under-$20 insurance policy against car fires by investing in an auto fire extinguisher like the Kidde 466310. The compact extinguisher weighs less than three pounds and is rated for use on liquids and gasses, as well as electrical equipment.

This model uses sodium bicarbonate to fight class B and C fires. It's only packed with enough chemical to discharge for eight or 10 seconds, but that should be enough time to nip a blaze in the bud. It comes with a convenient Velcro mounting bracket, so you can hang it in your car without worrying about drilling holes.

This model has a device that lets you check the extinguisher's pressure. It's made from powder-coated aluminum with a rust-resistant nylon handle. The Kidde 466310 auto fire extinguisher is covered by a 2-year limited warranty.
