    With the 1.1-pound Lighthouse ($80), you'll never be in the dark again. A full charge keeps everything illuminated for up to 48 hours, and if you run out of juice, you can hand-crank it back to life (one minute of cranking equals one minute of light) or attach it to an optional solar panel ($80) and let the sun do its thing.
