Indoor candle device is designed to keep phones charged

An emergency generator for your phone at time of power outages? That’s on offer in the form of a crowdfunded-campaign item called Candle Charger. It offers USB power when you need it, designed to keep phones souped up when the grid cannot. Two ingredients are involved: a candle and water, together behaving as a little indoor power plant for smartphones, to make sure you stay connected no matter what.
