77158 2.1 x 5.5mm DC Male to Male Extension Cable 22 AWG 1 ft.

Use this cable to extend low current power from components with a coaxial power output jack eliminating the need for an extra power supply. Dual screen portable DVD players have a 12 VDC output jack to power an extra monitor. If you don't need the extra monitor, send 12 VDC to an external powered speaker to enhance the sound quality. The 1 ft. cable is the perfect size to send power to stacked components, eliminating the need for an extra power adapter.
