Frequently Asked Questions
Q: What devices are compatible with this DC power extension cord?
A: This DC power extension cord uses the standard 5.5mm × 2.1mm barrel connector, making it compatible with a wide range of 12V DC devices including CCTV security cameras, IP cameras, LED strip lights, routers, wireless access points, and other low-voltage electronics that use this common connector size.
Q: Why is a copper-core DC extension cord better than alternatives?
A: Copper-core conductors offer superior electrical conductivity compared to copper-clad aluminum (CCA) alternatives. This means lower resistance across the cable length, reduced voltage drop, and more stable, consistent power delivery to your connected devices — especially important over longer runs of 3m or 5m.
Q: Can I use these cables with a DC power distribution bus bar?
A: Yes. These cables are specifically designed to work with DC 5.5×2.1mm public bus bars and power distribution boards, making them ideal for multi-camera security system installations where a single power supply feeds multiple devices.
Q: How many cables come in the set and what lengths are included?
A: Each set contains 5 cables with lengths of 1 meter, 1.5 meters, 2 meters, 3 meters, and 5 meters, giving you a versatile assortment for different routing needs in a single purchase.
