Frequently Asked Questions

Q: What devices are compatible with this DC power extension cable?

A: This 5.5mm × 2.1mm DC extension cable is compatible with any device that accepts a standard 2.1mm inner diameter / 5.5mm outer diameter barrel plug and operates between 5–24V DC/AC. Common compatible devices include CCTV cameras, IP cameras, LED strips, IR illuminators, DVRs, monitors, sensors, external hard drives, and audio equipment.

Q: How do I confirm this cable will fit my power adapter?

A: The most reliable way is to physically measure the inner and outer diameter of your adapter's barrel plug. The inner diameter should be 2.1mm and the outer diameter should be 5.5mm. If your adapter already uses this standard size, the DC extension cable will connect seamlessly.

Q: Will there be any power loss over a 10M cable run?

A: Thanks to the premium 22AWG copper conductors (17/0.15 AS×2), this cable is engineered for minimal resistivity. For typical low-voltage DC/AC applications in the 5–24V range, you can expect stable and consistent power delivery across the full 10M length.

Q: Can I use this cable outdoors?

A: This cable is designed primarily for indoor use. If you plan to use it in an outdoor environment, ensure the connectors and cable are adequately protected from moisture and the elements to maintain safe and reliable operation.
