I have a windshield glass breaking tool and seat belt cutter in my car. It also has a flashlight and an AM/FM radio. It has two AA rechargeable batteries but also has a hand crank. I can remove the batteries and use the hand crank at a reasonable speed to power the radio. I actually used it 20 years ago during an ice storm when there was no power for 5 days. I was able to hear news reports about where power was on and drive to a relatives house because the cell network was overloaded.
