Talk about a gift that says you care. This wind-up LED flashlight ($7.50 at Amazon) satisfies both our green and nerdy/practical tendencies.
It's super thoughtful -- the perfect addition to a home (or car) emergency kit -- sleek, LED-efficient, and never needs batteries.
We were actually just given one of these as part of an emergency kit at work -- and were mightily impressed. We've got to keep that one in arm's reach at work, so we definitely wouldn't mind finding one (or two) of these in our stocking this year.
If you're looking for something a bit more intense, this version ($9.49 at Amazon) packs a bit more of a punch with a self-powered 4-in-1 FM radio, alarm, and mobile phone charger.
