2m long extension cord with a master switch and outlet guard. - Brand: MSCIEN - Model: YP09R08 - Length: 2m - Retail Price: ¥3,499 Purchase Date: December 2024, purchased on Amazon Used indoors at home for about six months. Wiped down with an alcohol wet sheet, but there are a few spots of dirt that couldn't be removed (images 6 and 7). The purple stain in image 6 is likely ink from a ballpoint pen. Operation seems to be problem-free. Shipping via Takkyubin Compact. The box will not be included if it doesn't fit. Only the main unit and the instruction manual (in a bag) will be included. The following is excerpted from Amazon: Safe and Built-in Surge Protection: The power strip cover hides the entire outlet, helping to prevent children and pets from unplugging plugs and getting electrocuted. Built-in surge protection effectively prevents appliance failures caused by power surges. The power strip uses heat-resistant synthetic resin, which helps prevent electric shock and fire. Non-Interfering and Master Switch: The distance between the AC outlets is appropriate, and the layout is rational, so many AC adapters can be inserted simultaneously without interference, resulting in a neat appearance. It also has a master switch to save power.
