DC Power Extension Cable 3.5mm×1.35mm Female to Male 5V 2A
DC Power Extension Cable 3.5mm×1.35mm Female to Male 5V 2A
DC Power Extension Cable — 3.5mm × 1.35mm, 5V 2A, All-Copper Core
Need a little extra reach for your power adapter? This DC Extension Cable bridges the gap between your power supply and your device with a clean, secure connection. Built with a 100% all-copper core, it delivers consistent, stable current — none of the voltage drop or heat build-up you get with cheaper, mixed-metal alternatives.
Whether you're extending power to a CCTV camera, LED strip light, router, smart home hub, or any device running on a 5.5mm × 2.1mm or 3.5mm × 1.35mm DC plug, this cable is ready to do the job right.

Why Choose an All-Copper Core Cable?
Many budget cables use copper-clad aluminum (CCA) wire, which has higher resistance and can overheat under sustained load. This cable uses pure copper conductors throughout, keeping resistance low, temperatures safe, and your connected devices running reliably — even over longer cable runs.
Common Applications
- CCTV & security cameras
- LED strip lights & LED drivers
- Routers, modems & smart home devices
- Desk fans, small speakers & electronics
- Any 5V DC-powered accessory using a 3.5mm × 1.35mm barrel connector
Package Contents
- 1 × DC Extension Cable (selected length)

Frequently Asked Questions
Q: What devices is this DC extension cable compatible with?
A: This cable is compatible with any device that uses a 3.5mm × 1.35mm DC barrel connector and operates at 5V DC. Common uses include CCTV cameras, LED strip lights, routers, smart home hubs, and other low-voltage electronics. Always verify your device's connector size and voltage before use.
Q: How much current can this cable handle?
A: Cables in lengths of 1M to 5M support currents up to 4A. The 10M length supports up to 5A. The all-copper core construction keeps resistance low, making it suitable for sustained loads within these ratings.
Q: Why does the copper core matter?
A: Pure copper has significantly lower electrical resistance than copper-clad alternatives. This means less energy is lost as heat, your devices receive a stable, consistent voltage, and the cable remains cool and safe during extended use — especially important for longer cable runs or higher-current applications.
Q: Can I use this cable outdoors for my security camera?
A: This cable is designed for general indoor and protected outdoor use. If routing the cable in exposed outdoor environments, we recommend protecting the connection points from direct moisture with weatherproof covers or conduit for best long-term performance.
