Extend Your Power Reach with Confidence

The DC Power Extension Cable by Tendelux is built for anyone who needs to bridge the gap between a power adapter and a device that's just out of reach. Available in 5M and 10M lengths, this premium 22AWG copper extension cord delivers reliable, stable power to a wide range of DC/AC equipment — all through a standard 5.5mm × 2.1mm barrel connector. Made in Mainland China.

Why Choose This DC Extension Cable?

Premium 22AWG Copper Wire (17/0.15 AS×2): High-conductivity copper construction means lower resistivity and consistent power delivery over the full cable length — no unwanted voltage drop.
5M or 10M Length Options: Whether you need a modest reach or the full 10 metres, there's a length to match your installation needs — perfect when your device can't be positioned close to an outlet.
Universal 5.5mm × 2.1mm Barrel Connector: Female input on one end, male output on the other. Compatible with any device that accepts this standard plug size.
Works with 5–24V DC/AC Devices: Designed for a broad voltage range, making it suitable for security cameras, LED strip lights, sensors, DVR units, audio equipment, monitors, printers, external hard drives, IR illuminators, LED signage, and more.
Flexible & Durable Jacket: The outer insulation is built to withstand everyday bending, routing, and installation without cracking or fraying.

Frequently Asked Questions

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

A: This DC power extension cable is compatible with any device that uses a 5.5mm outer diameter × 2.1mm inner diameter barrel connector and operates between 5–24 volts DC or AC. Common compatible devices include CCTV cameras, IP cameras, LED strip lights, IR illuminators, DVR/NVR units, monitors, printers, sensors, external hard drives, and audio recording equipment.

Q: Will there be power loss or voltage drop over the 10M length?

A: This cable uses premium 22AWG copper wire (17/0.15 AS×2) chosen for its low resistivity and high electrical conductivity. For typical low-voltage DC applications within the 5–24V range, the voltage drop over 10 metres is minimal and should not affect the performance of compatible devices.

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

A: The surest method is to measure your adapter's plug: if the outer diameter is 5.5mm and the inner (pin) diameter is 2.1mm, this cable will fit. If you are unsure, consult your device or adapter's manual for plug size specifications before purchasing.

Q: Can this cable be used outdoors for security camera installations?

A: This cable is primarily designed for indoor use. For outdoor CCTV or IP camera installations, ensure the cable is routed through conduit or protected from direct weather exposure to maintain long-term performance and safety.
