Thanks. This information is helpful.
I see little point in trying to save most sophisticated electronics since they will be of little use without supporting infrastructure. Probably little point in saving computer data since it is of little uses without computers and electrical infrastructure.
I would try to save the simpler types of LED flashlight and some basic radio broadcast receivers.
Computer backup takes up little space and it will come in handy if I get another computer, after I bug out to a location not hit by an EMP.
I have two of my flashlights in protective containers.
