About Product

LNF4S4U-WA series surge protector LYAMBDA with four USB ports and four Euro socketsis an indispensable electrical accessory for home, apartment and office.

It allows you to solve the problem of a lack of sockets in your home or office and connect a large number of equipment as well as charge phones and other gadgets due to the fact that there is a USB socket.

1. Power regulation: Surge protectors have the ability to regulate and stabilize the voltage that goes to the devices connected to them, providing them with a stable and safe power supply.

2. Overvoltage and Short Circuit Protection:Surge protectors are designed to protect connected electronics from overvoltage and short circuits. They have a safety feature that shuts down the electrical circuit when such problems occur, preventing damage to connected devices.

3. Interference filtering: Surge filters provide filtering for various electromagnetic interference that may come through the power line. They remove or reduce interference, such as high-frequency pulses and noise, and prevent them from entering connected devices.

4. Organization of connected devices: Surge Protectors offers one USB-C PD 20W port, one USB-A QC 3.0 and two standard USB-A ports and four outlets for connecting devices. This allows you to conveniently organize and connect computers, TVs, chargers, audio-video equipment and other electronic devices to provide a safe and structured power supply for each of them. You no longer need to look for additional chargers or wires - everything can be connected directly to the filter.

5. Safety. Four Euro sockets with childproof safety shutters make this filter an ideal choice for families with children or in areas where there are small children. The built-in switch allows you to turn off the power to connected electrical appliances with one click, without removing the electrical plug from the outlet. Before shipping, the extension cord undergoes a quality check and is securely packaged.
