I've used the dry powder type extinguishers many times on all kinds of fires, car fires, kitchen fires, brush fires, mattress fires etc. They're disappointing. They only give you about a 10 second blast and they don't do a lot of good unless you use several of them even on a small fire. With a dry powder extinguisher your goal is to separate the fuel source from oxygen by burying it in powder. One extinguisher is rarely enough. They only work on certain kinds of fires. Attempts to put out propane or gasoline fires are a waste of time and very dangerous. Extinguishers also make a really big mess. Even when you think it's out it will very often re-ignite. If you don't use it right it will actually spread the fire. I keep them both in my home and in my RV mainly because Insurance Companies demand them. I don't expect one lonely fire extinguisher to do a lot of good. If there's a fire in either my home or my RV I will give it that 10 second blast and just get everyone out. Of course, the best way is not to have a fire in the first place. Instead of practicing how to use an extinguisher, I suggest you practice on how to get everyone away from the fire.
