You know what? I think that it is always handy to have power tools in the house. Sometimes there will be tasks that you need to do and you would need these tools. Of course, they are not “immediate needs”, as opposed to food and medicines, but if you have extra money, it would be nice to invest in them. Not all of them are powered by Makita batteries, as some of them can just be plugged into an electric socket.
One handy tool in the house would be a power drill so that whenever you need to hang something up the wall, you can easily drills holes and insert a hook. There is a host of tools that we can add in the house. They make housework handy.
