Heat Powered Charger

Power up your smart phone while drinking your hot coffee in the morning or with that cold glass of beer you’re holding at night! If you’re in rush and your time is valuable, this cleverly designed device is a life saver since you don’t need to search for an outlet to charge your phone. Use that cup of coffee to recharge both you and your smart phone at the same time.
This Heat Powered Charger is tiny, lightweight and portable. It is designed to produce 5 watts at maximum output, which is the same as a standard smart phone charger.
