The V57PW HDMI® Power Inserter is a device designed to power both sides (2-way) of an HDMI circuit. This short coupler cable with a power jack and included USB power supply and cable is ideal to couple two active HDMI cables together. This unit has one end designed to be mounted on a wall plate as the Host receiving end. A short 150mm cable joins the Client receptacle for the remote end. The flexible cable allows the exit HDMI cable to be routed for least stress on the cable.
