I have standard Kidde fire extinguishers in my house, but they are not really suitable for a car. Recently i got a 93 Corvette, and I like to drive it. It needs its own fire extinguisher, and this is it! Luckily, I can't really comment on their effectiveness in an actual fire, and I hope I never find out.
Thankfully, we have not had to use this fire extinguisher, but we are prepared in the event that we have a fire, as it is in a convenient location and it came with simple instructions for mounting and using. Our whole tamily had been trained how to use it. It is compact, light. And very easy to operate. Every household should have one and be prepared in the event that there is a fire.
If you want to be prepared in case of a fire emergency in your auto or your boat, the Kidde Auto/Marine Fire Extinguisher is the way to go! A compact fire extinguisher suitable for use on fires of liquids and gases (class B) and energized electrical equipment (class c)-with graphics on the fire extinguisher indicating these clases. Easy-to- read and clear (at a glance) instructions with graphics in how to operate the fire extinguisher are on the fire extinguisher itself. The gauge easily indicates the fire extinguisher is completely charged and ready to use: green means full and red means empty. Both the graphic instructions and classes are in Spanish on the fire extinguisher as well as on the box. With this lightweight fire extinguisher, that is UL listed you not only are preparing yourself for an emergency situation, but it gives you peace of mind. Great not only for autos, trucks and boats, but also for your RVs. It is easy to spot given it is a white fire extinguisher. I also take it with me when going camping. It is an additional preparedmness in case of a fire emergency. Although it is a single use unit, it is wise to have one at least in your vehicles. Do recommend it!
If you have a motorized boat or a car or a truck, you should have fire extinguisher on board. Seriously, why would you not have one of these at hand. We all wear seat belts and carry life jackets to protect us in case of an accident. Carrying a fire extinguisher is the logical next step in the safety cycle. I have been fortunate that I have never had to use a fire extinguisher on my own boat or vehicle, but I have used one more than once to help out others. Keep in mind that simply owning a fire extinguisher is not enough. You need to make sure that it is securely mounted in an accessible location (there are a ton of videos out there with suggested locations and mounting methods). You also need to regularly check the device to make sure that it has not lost its charge. Once the charge indicator shows the charge has dropped below the optimum level, I have used the unit as a demonstration piece when teaching fire safety to our Scout troop. Even though a device indicates the charge is not enough to fight a full fire, there is always enough residual charge for demonstration purposes. Needless to say, I strongly recommend that everyone should carry a fire extinguisher. Furthermore, when it comes time to select a unit, make sure that you get one from a reputable company like Kidde. They have long produced some of the most reliable fire extinguishers on the market.
This is a review of a fire extinguisher for cars or boats The strap that fastens the extinguisher to the bracket is just plastic and something small. It is only for use in cars or boats. It is not for kitchens. It is not rechargeable. It should be replaced at 6 years preferably. It is very useful to be cautious and have a fire extinguisher in the trunk of each vehicle, in the trailer, or in the boat. Since it can be very useful for your own use or to help someone else. Check when you buy it that it has the clip and the support in good condition because it is plastic. It is class B Liquids and Gases and class C for electrical equipment. It has graphic instructions to follow step by step It weighs approximately 4 pounds
This extinguisher is rated B & C which means it can be used on liquid fires and electrical fires. This will be a good safety device to keep in your car or on your boat. It is Coast Guard Approved. It also has the UL seal of approval. It has very clear instructions on the proper use actually on the device, and a easy to read dial to check if it is full and ready to use. It also has the typical safety pin which must be removed to activate the extinguisher. It comes with a standard wall mount if you choose to hang it in an appropriate place. The manufactored date is nicely stamped on the bottom. Remember, this extinisher should be replaced within 12 years of the date of manufacture. It also must be replaced upon being discharged or any damage to it. Knowing where it is kept and how to use it could save your valuable property or a life.
I received this as part of the Wal-Mart Spark review program. I got this particular fire extinguisher because it would work on all types of fires. It is a dry powder extinguisher so it is perfect for grease, electrical or any type of fire. I mounted this in the back of my truck, as I have had a car fire before and no extinguisher. It mounted very easily to the truck, and the mount is a very good sturdy mount. It just screwed into the back of the tool box, where it is stored. It is just the right size for the tool box, and doesn't take up a lot of room. It is big enough to put out a fire without being bulky. It is easy to operate as you just break the seal and shoot at the fire. I would recommend this to anyone that wants peace of mind about a car fire or any fire.
The Kidde Auto / Marine fire Extinguisher is suitable for use on Class B fires, which are for liquids and gases, and Class C fires, which is for electrical equipment fires. This extinguisher unit is fitted with a pressure gauge that provides at-a-glance status. This extinguisher also comes with a plastic bracket that enables you to mount it to a wall for easy access. To be honest the bracket looks a little flimsy to hold up this extinguisher which is quite substantial. Since I have a cabinet right next to the area I want to put it the mounting bracket is unnecessary for me so I mention it for information only. How well this extinguisher will actually work in a fire situation is, of course, theoretical since it is a one time use item. After one use or twelve years the extinguisher should be disposed of and replaced. Therefore I can give no first hand testimony as to how well it preforms but it appears well built and I think it will work as promised.
I have always had a fire extinguisher in my boat and car for as long as I can remember. I have been fortunate as I have never had the occasion to actually use one. I have long trusted the name Kidde and although there are many choices out there, these seem to hold their charge a lot longer than some. I am somewhat disappointed that the mounting strap is now plastic. In fact the strap was actually broken on the one I received, so, if you purchase this type, be sure to check the strap is attached to the bracket. Having never had to use them, I cannot say how well they perform.
Ordered online and received a product manufactured in 2019 and ended it's life cycle effectively. A typical fire extinguisher life span would be 6 years. Walmart guys havent even checked the manufactured date and delivered me a already expired fire extinguisher, one made in 2019 sold to me in 2025.
