Frequently Asked Questions

Q: What devices are compatible with this 5.5mm × 2.1mm DC power extension cord?

A: This DC power extension cord is compatible with any device that uses a standard 5.5mm outer / 2.1mm inner barrel connector and operates within 5–24V DC/AC. Common compatible devices include CCTV cameras, IP cameras, LED strip lights, IR illuminators, DVRs, monitors, printers, external hard drives, and audio recording equipment.

Q: What is the difference between the 5M and 10M versions?

A: Both versions use the same high-quality 22AWG copper wiring and 5.5mm × 2.1mm connectors. The 5M (~16.4 ft) version suits shorter runs such as desktop or counter setups, while the 10M (~32.8 ft) version is ideal for longer installations like ceiling-mounted cameras or multi-room equipment.

Q: Will this cable cause any power loss or voltage drop over its length?

A: Thanks to the premium 22AWG copper conductors with 17/0.15 AS×2 construction, this cable is engineered for minimal resistivity and excellent electrical conductivity, ensuring stable power delivery across the full cable length within the rated 5–24V range.

Q: How do I check if this cable's plug matches my device?

A: The easiest way is to measure your power adapter's plug: the outer barrel diameter should be 5.5mm and the inner pin diameter should be 2.1mm. You can also consult your device's manual or the label on the power adapter itself.
