Off you stumble, in the dark, to try to find what you need. This is an accident waiting to happen. You can trip on shoes and fall, run into a door you thought was open, stab yourself on something sharp when feeling around in a drawer. What if your flashlight batteries are dead, and you don't have any matches? What will you do?
It's very simple to avoid this situation. Make a power failure kit. You can put it in a box, assign it a drawer or keep it in a duffel bag. As long as you know where it is at all times, you'll be good!
This is the lantern and oil that I have in my kit. I got them from Amazon for about $20. The lamp comes with a wick, but you may want to buy some extras.
Another really important thing for you to have in your power failure kit is a portable radio and extra batteries. It does not have to be a fancy emergency radio, it can be any battery operated radio that will get local channels for weather reports and hopefully reports on when the power will be coming back on.
Have a great weekend,
