Will a crank charging flashlight still work after an EMP or nuclear strike?

Question

I have this little LED flashlight/ radio combo gadget that you recharge by turning a crank on it. Will I still be able to crank it up and work it after and EMP or Nuke strike?

Its a DuraPro Selfpowered Flashlight.

Answer 1

The generator and LED light would probably still work, but the radio would probably be destroyed.

If you are really worried about such things, all you have to do is seal the radio inside of aluminum foil. Make it air-tight, or wrap it with a double layer of foil, overlapping any foil joints.

Answer 3

A nuke blast destroys pretty much anything, unless you're far enough away. The EMP may damage the components, depending on how strong the pulse is and the sensitivity of the diodes, etc. in the device. The guy above me offers a simple solution, what's called a "Faraday Cage". By covering the object in a conductor, external fields are greatly attenuated inside the conductor.

Answer 4

Because it's an LED flashlight, there must be a rectifier circuit somewhere in there that converts the generator's AC output to DC. Silicon-based electronics (such as the LEDs and the rectifier) would likely be damaged in an EMP.

Answer 5

There is a chance it could. It would depend on the power of the EMP pulse. If the EMP pulse was large enough, it would destroy most electronics (including those in the flashlight). However, a weak one far away might not damage the flashlight.

Answer 6

Because of the solid state components, maybe not. Solid state is very susceptible to nuclear radiation. A safe place for such things, at least as replacement parts would be a hole, tunnel, or heavily shielded concrete shelter of 3 feet thickness or better. The generator itself should not be affected.
