If your device uses a 5.5mm outer \/ 2.1mm inner barrel jack, this cable is compatible.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this cable to extend the power supply for a 12V CCTV camera?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the 5521 connector the same as a 5.5×2.1mm barrel connector?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How many cables are included in the package?\u003c\/h4\u003e\n\u003cp\u003eA: This listing includes 2 pieces of the DC power extension cable, giving you a spare for future installations or system expansions.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What devices are compatible with the 5521 DC power extension cable?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"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.
