Frequently Asked Questions
Q: What devices are compatible with the 5521 DC power extension cable?
A: The 5.5×2.1mm (5521) barrel connector is the most common DC power standard for CCTV and IP security cameras, DVR/NVR units, 12V LED strips, routers, wireless access points, and many other DC-powered electronics. If your device uses a 5.5mm outer / 2.1mm inner barrel jack, this cable is compatible.
Q: Can I use this cable to extend the power supply for a 12V CCTV camera?
A: Yes. This male-to-female DC extension cord is specifically designed for CCTV camera power runs. It maintains a stable 12V DC connection over the extension length, making it ideal for installations where the power adapter cannot reach the camera directly.
Q: Is the 5521 connector the same as a 5.5×2.1mm barrel connector?
A: Yes — "5521" is simply the shorthand designation for a barrel connector with a 5.5mm outer diameter and a 2.1mm inner pin. This is the most widely used size for CCTV cameras and general DC power adapters, so it offers broad compatibility with off-the-shelf equipment.
Q: How many cables are included in the package?
A: This listing includes 2 pieces of the DC power extension cable, giving you a spare for future installations or system expansions.
