Powermax 4-Way Extension
The Powermax 4-Way Surge Protector provides critical electrical safeguarding for sensitive IT infrastructure and professional workstation deployments. This hardware integrates four surge-protected AC sockets with advanced charging ports to streamline desktop power management and peripheral connectivity. It utilizes high-grade Metal Oxide Varistor technology to divert transient voltage spikes away from connected equipment during electrical disturbances. The EX-PM4+USB+C model specifically addresses the needs of modern environments by including a dedicated USB-C port alongside dual USB-A charging interfaces. This configuration supports a maximum load of 13 Amps at 250 Volts, making it suitable for high-demand hardware. The internal architecture utilizes high-conductivity copper busbars to ensure efficient power delivery with minimal resistance. Each socket includes an individual safety shutter mechanism to prevent accidental contact with live terminals. The enclosure consists of flame-retardant polycarbonate materials designed to withstand significant thermal stress without deformation.

This Powermax EX-PM4 is exactly what I needed for the living room. Most extensions only have the standard USB-A, but having that Type-C port means I don’t need to look for charging bricks all the time. It handles the TV, decoder, and soundbar without heating up. It’s a solid surge protector, much better than those cheap ones you find in downtown shops. Highly recommend if you want to protect your electronics from these KPLC surges.

Good value for the money. I’m using it for my home office setup in Syokimau where power fluctuates a lot. The 4 sockets are well-spaced, so the big adapters don’t block each other. Delivery to my place was fast.
