Solve the "Single Port" Dilemma

In many Hong Kong apartments and offices, rooms are often equipped with only one embedded network port. When you need to connect both a desktop computer and a game console (or a Smart TV and a set-top box), you’re usually forced to choose or buy an expensive, bulky network switch. This RJ45 1-to-2 Splitter solves this problem instantly by splitting one input into two active outputs.

Stable 100Mbps Transmission for Work and Play

Equipped with a USB power cable, this adapter provides the necessary voltage to maintain a consistent 100Mbps connection across both ports. Whether you are streaming 4K content on your TV or engaged in a high-stakes e-sports match, the pure copper core and metal shielding ensure zero signal loss and protection against electromagnetic interference (EMI).
