We have the canned goods, the dry goods, the water filter, the ammo, an emergency trunk filled with everything you can think of—drugs, first aid, lanterns, etc.
But I’m sitting here in the dark for hours after a transformer blew in our small village. Totally failed our dry run. I can’t get the lanterns working. Our batteries seem corrupted and I don’t have the right kind of batteries in some instances. And I need a lantern that uses another kind of energy too.
Big fail! I’m off to Home Depot when the lights come on to truly get prepared. Glad this happened today. I thought we were in good shape. Didn’t make it an hour.
"water filter"?
What about water? This is by far the most important item. I'm on a well and have no generator big enough that can power the well. I keep 30 gallons in 5 gallon "cubes" on hand at all times. They came in handy when our well failed one weekend and more recently when the Houston derecho left us without power for 72 hours.

Additionally, if you know something is coming, fill your bathtubs with water. These can be used for bathing. I wouldn't get into them to bathe, but I'd dip out enough of that water to shower with in some manner.
and MAKE SURE THE RUBBER STOPPER PLUG IS SOUND.
One year in a storm outage we realized our tub's stopper had hardened and water was leaking past it. Had we not noticed, the tub would have just slowly drained overnight. Managed to put a couple layers of plastic between stopper and plug socket. It worked, and there was still some system pressure to refill fortunately.
