I have an older Kindle reader with downloaded manuals and lots of old books of all genres for educational and reference purposes. Downloads are free and the Kindle almost was. Also have a good AA and AAA battery charger that runs off a small solar panel. With that, I have 20 Eneloop rechargeable batteries: from Amazon, rechargeable for longer than we'll need them and they stay charged when not in use! Excellent buys. Also have a cheap digital shortwave receiver, recharges through a usb cable. Also a spare $20 charge controller (also with USB charging ports) to keep a 12v battery charged from a solar panel (every car will have a good battery and the car probably won't be).
In addition, I included an old Ham radio from a flea market that works really well on CW and will run on 12 volts. Once that was "in the can" (literally), I still have room for new adds. It takes a while to get the basics together, but it's enough to keep a few LEDs working, batteries charged, and be able to keep informed as well as maybe contact others. Not perfect, but good insurance, IMHO.
We are far too interconnected for anything to function without power, and two weeks without will cause a systemic collapse since most people have less than three days' food on hand.
ALSO: Do have at least a pair of the small walkie-talkie type radios marketed for campers.( Amazon has the BaoFeng BF-888S at $24 for a pair, and they are excellent. ) Under a SHTF scenario, those would replace cell phones for neighborhood use. I have a few for neighbors, just in case, since they will be early warning points for trouble.
BTW, an EMP is the Pentagon's #1 concern. It can happen without warning, and it is certain to happen in a real war, not matter who starts one, according the those in the know. Those same folks have questions about one of the two NK satellites that pass overhead every 90 minutes.
