This is a 50-centimeter black DC power cable with dual 5.5×2.5mm male plugs at both ends, used to extend or connect two DC devices with matching round power ports.
The wire adopts high-conductivity copper conductor wrapped with flexible black insulating outer layer, which is wear-resistant and anti-aging for long-term indoor use. Reinforced plastic strain relief at the connection of plugs effectively avoids wire cracking caused by repeated bending and pulling.
It supports standard low-voltage DC power transmission, ideal for DIY wiring, surveillance system installation, LED light arrangement and daily backup power connection. Plug-and-play without extra tools, compact and easy to store when not in use.
