Due to the massive application of large forklifts operating in factories, warehouses and logistics, the conventional industrial chargers are designed with large size, heavy weight and difficult to move. However, with the portable charger comes into being in the market, industrial charger featuring small size and flexible application scenarios become one of the top options.

In general, because of its small size, compact structure and light weight, portable chargers are easy to carry along at any time, to any place. Most of portable chargers are designed with adjustable current and voltage to fit in with different models of electric vehicles such as automobiles and electric bicycles. Moreover, as the portable chargers will be moving around and placed at different locations, a much higher degree of intelligence and security is taken into consideration, therefore, hi-tech functions such as digital precision monitoring, reserved force-charge, hardware and software over-current and over-voltage protection at the front and rear end are commonly found in recent days.
