Hey, Nomad and others, can you give us specific equipment recommendations? I've been prepping only for the 3-day model -- so that means some store-bought batteries would do. What do you recommend in the way of:

-- FRS/GMRS radios
-- Solar charger

Also, while I knew about Eneloops, I don't know about 18650. A quick googling suggests to me that they aren't compatible in size with AA. I'm assuming they aren't compatible with AA devices. How do you use 18650? With super-power flashlights?
