Safe and Reliable: The built-in ground fault circuit interrupter (GFCI) provides comprehensive leakage protection, as well as overload and short-circuit protection. If a leakage, overload, or short-circuit fault occurs, it automatically cuts off power within 0.1 seconds, effectively preventing electric shock and potential fire risks. It's particularly suitable for environments where power tools and other electrical equipment are frequently used. Main Switch and Wide Spacing: This heavy-duty power strip socket has a main switch that can cut off the power with one click, reducing the trouble of frequent unplugging, improving safety, energy saving and convenience, and also comes with 4 plugs (15A/1875W), with wide spacing between sockets, which can power 4 devices at the same time, meeting the actual use needs in life. Wide Range of Uses: This socket is well-made, the shell is sturdy and durable, and it is made of ABS+PC material, which has high strength, good toughness, high t
