Like a technological Swiss Army Knife, the Eton Scorpion ($50) is an all-in-one digital solution. Built into its small, rugged chassis is an aluminum carabiner clip, digital AM/FM radio tuner with NOAA Weatherband support, a speaker with audio line input, a headphone jack, a LED flashlight, and an USB charging port, all of which can be powered by a traditional DC connection, the built-in solar panel, or the built-in hand crank — you know, in case the fallout is blocking the sun.
