Thanks to a new thermoelectric device design embedded in the bottle cap, it has a USB charging port. By connecting the recharging cable, the battery charging icon on the mobile screen is activated.
The water bottle can provide 20-30 minutes of electricity after we pour 300-500 milliliters of boiling water. Enough to charge a smartphone and other small appliances.
Thermoelectric device
Thermoelectric devices are made of materials that can convert a difference in temperature into electricity.
Researchers at the China Academy of Launch Vehicle Technology, a Chinese manufacturer of space rockets, have developed a type of insulated water bottle equipped with a thermoelectric chip that converts heat from water into electricity to charge devices.
Emphasizing the safety of the invention, its developers guarantee that it produces low voltage and has no risk of a short circuit.
The researchers are now looking to establish cooperation with companies to commercialize the concept . The product is likely to be priced at 150 yuan, about 20 euros.
