CUBE 4-WAYS POWER SOCKET, 3 USB,1 TYPE C FAST CHARGING PORTS

You need them to plug in your devices and appliances.
But are you using extension boxes that protect your appliances? Most times, people don't. They go for cheaper, ordinary extension boxes...
Unfortunately, ordinary extension boxes offer no protection. When you use them, your appliances are exposed to the full risk of damage from power surges, lightning strikes and myraid other power issues that can damage your expensive appliances and devices. When you save on cost of extension box and end up with risk of damage to your sensitive TVs, home theater system, decoder, iphones and other phones, laptops, printers, tablets, WiFi modems, projectors and other prized appliances, you need to think again!
Plugging expensive, high sensitivity appliances like laptops, desktop PCs, phones, TVs, etc into basic power extension boxes is not the wisest thing to do. They offer no protection against power surge, thunder, overload, and other power hazards that could damage your precious equipment. They may be cheaper, but they put your expensive devices at risk!
