The built-in overcurrent protection in every Shenzhen Green Ocean charger keeps both the unit and the car safe when too much current flows. It watches the current the whole time the battery is filling up. If the flow goes above a preset limit, the system shuts things down right away so wires dont overheat, parts dont burn out, and no one gets hurt. Approved by international bodies, the feature is in every Shenzhen model. Whether you pick a single-phase unit or a Type 2 version, the protection runs smoothly under different voltages and makes the chargers good for homes, fleets, and almost any public outlet.
