Solar Power LED Bottle Cap For Water Bottles
This is so cool!! Turn your water bottle into a solar-powered lantern with this waterproof cap. Just fill the bottle with water and screw on this cap to create a lantern that will illuminate your campsite, tent or home.
An embedded solar panel charges a long-lasting NiMH battery to power four bright LEDs- simply leave it out in the sun for a few hours and you’ll have up to 12 hours of light.
