A new kind of battery that can charge an iPhone or Android smartphone using a bank card is gaining traction in China.
A startup called SolarBattery, based in Hong Kong, said it has developed a rechargeable battery that it says can charge a solar panel at home from a USB cable.
The company’s patent application, filed on June 12, says that the solar panel can be charged from a bank credit card or another electronic device by using a special voltage converter.
It says the converter converts between the voltage in the battery and the voltage on the charger.
The converter also allows for easy charging of the battery from a computer.
The startup said it plans to expand the technology to other applications, including a solar-powered smart light that can automatically turn on and off automatically, or an electric car that can recharge the battery when it’s parked in a garage.
