Compact 3.3 ft DC extension pair

This 2-pack of Security-01 DC power extension cords adds 3.3 feet of reach to any 5.5 mm x 2.1 mm barrel connector. Each white cable carries up to 3 A at 5 V, 6 V, 9 V, 12 V or 24 V. The male-to-female design plugs directly into existing adapters for security cameras, DVRs, LED strips, routers and similar low-voltage gear.

Stable output over long runs

Copper conductors and a PVC jacket maintain consistent voltage delivery across the full 3.3 ft length without measurable drop at the rated 3 A load. Tight-fitting barrel ends resist accidental disconnection from vibration or cable movement, so cameras and sensors stay powered during continuous 24-hour operation.

Replaces short factory leads

The cords solve the common problem of stock power cables that fall 1–2 feet short of the nearest outlet. They are not suited for runs beyond 3.3 ft or for devices drawing more than 3 A, and they do not convert voltage or polarity.

Questions about this item

Does the 5.5 mm × 2.1 mm barrel connector run warm when the cord carries its 3 A maximum for hours?

The copper conductors and PVC jacket are rated for the stated 3 A limit, so the connector stays within normal operating temperature during continuous use at that load.

What must my device already have for this extension to fit?

Your equipment needs a 5.5 mm outer-diameter by 2.1 mm inner-diameter DC power jack, the industry-standard barrel port used on most 5 V to 24 V gear.

Can I daisy-chain several of these 3.3 ft cords to reach an older CCTV camera without voltage problems?

Yes, the spec allows two or more cords to be connected together; total length adds resistance, so keep the combined run as short as practical for 12 V or 24 V cameras.
