    Smart power banks support high voltage charging

    Power banks are becoming more and more popular as battery capacity outstrips the runtime of personal electronic devices like smartphones and tablets. High-performance CPUs, large sizes and high-resolution display panels also make runtimes shorter. This creates an demand for a fast-charging backup battery such as a power banks. Traditionally, a 5V...
