Frequently Asked Questions

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

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

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

A: Measure the inner diameter (ID) and outer diameter (OD) of your power adapter's plug. This extension cable supports a 2.1mm inner diameter and 5.5mm outer diameter barrel connector. If your adapter matches these measurements and operates within 5–24V, this cable is compatible.

Q: Will there be any power loss over the 10-metre length?

A: The cable uses 22AWG premium copper conductors with low resistivity, which minimises voltage drop over the full 10-metre length. It is engineered for reliable, stable power delivery across its rated voltage range of 5–24V.

Q: Can this cable be used outdoors?

A: This cable is primarily designed for indoor use. If you plan to route it in an exposed outdoor environment, we recommend protecting it with an appropriate conduit or weatherproof housing to ensure longevity and safety.
