Put an old cell phone and one of those hand crank flashlights with a charging port with any other supplies you cache. Around here you can find old cell phones for $5.00 at garage sales. No need for it to be active as they all work to call 911 without service. Even with a junk battery, the hand crank generator after several min of cranking would charge it enough to make a short 911 call.
