Y-Style Power Cord Splitter Connects 2 Devices with 5-15P Plugs to One AC Outlet
This extension cable splitter allows two devices with NEMA 5-15P plugs to share one AC input cord and one C13 power outlet. The AC power splitter features a C14 inlet for connecting to an AC power source and two 5-15R ends for connecting to devices’ power cords. By connecting two devices to one power outlet, the splitter frees up space in a PDU or surge protector, reduces cable clutter and allows welcome flexibility in placing equipment with respect to the outlet.
