No extra batteries needed with the LuminAID light. This ingenious idea was designed to fulfill the basic need for light in post-disaster situations. Disaster zones are probably not the first place you’ll be traveling to, but the LuminAID will be perfect for your next camping or adventure trip. This compact and inflatable solar-powered lantern can be tucked into your bag, or clipped to your backpack. A charge of 5 hours of direct sunlight will give you about 6-8 hours of light on the high setting, and 8-10 hours on low. To use, simply inflate and press the power button. If you find yourself caught in the rain or out on the water, you’ll also like to know your inflatable LED will float, and is waterproof up to 1 meter deep. Get one here, but if you already have a thousand types of flashlights, you may be interested in sponsoring a LuminAID for those who are in need.
