This 90 cm black DC pigtail cable handles up to 5 A continuous, making it the right choice for higher-current 12 V loads. It is built for powering 12 V DC equipment up to 5 amps over a longer 90 cm run with reduced voltage drop and ships ready to plug into compatible adapters, routers, CCTV cameras, LED lighting, and DIY 12 V projects. Tinned copper conductors and PVC insulation deliver stable performance from -20 °C to +80 °C.
Product Description
This is a 20 AWG DC pigtail cable rated for 12 V DC at up to 5 A, terminated with a female barrel jack, 5.5 mm OD x 2.1 mm ID. It is designed to replace damaged power leads, extend reach between an adapter and a device, or serve as the power input on a custom build. The conductor is tinned copper, which resists oxidation and keeps contact resistance low over time, and the insulation is PVC with standard red-positive / black-negative color coding so polarity is unambiguous during installation.
The cable ships as a finished assembly — no soldering is required to use it as-is — but the open-lead variants are also straightforward to terminate with screw terminals, ferrules, or solder for permanent installs. Total assembled mass is low enough that the cable does not pull on panel-mount jacks or strain the device under normal handling.
Key Benefits
- ⚡ Ready-to-use 20 AWG assembly — no soldering required for plug-and-play replacement
- ✅ Tinned copper conductor for low contact resistance and long service life
- 🛡️ Color-coded insulation (red +, black -) eliminates polarity guesswork
- 🔌 Universal 5.5 mm OD x 2.1 mm ID jack fits the most common DC barrel-jack standard worldwide
- 🌡️ Operating range -20 °C to +80 °C covers indoor, outdoor enclosed, and automotive use
Key Features
The first feature worth flagging is the 20 AWG conductor cross-section, which is sized for the rated current with margin: at 5 A, the cable carries less than 70% of its conservative ampacity, so warm-up under continuous load is minimal. The female barrel jack, 5.5 mm OD x 2.1 mm ID matches the 5.5 x 2.1 mm DC barrel-jack standard found on the majority of 12 V consumer adapters, making this cable a drop-in replacement in most situations. The PVC jacket is flexible enough for tight bends behind enclosures and stiff enough to resist kinking when pulled through wire raceways.

What's Included
- 1 x 20 AWG DC pigtail cable assembly (per selected variant)
Compatibility & Applications
This cable is compatible with any device, adapter, or supply that uses a 5.5 x 2.1 mm center-positive DC barrel jack at 12 V DC and that draws no more than 5 A continuous. Typical applications include:
- CCTV camera systems
- Automotive 12 V LED lighting
- Power adapter repair and replacement
- DC bench power supplies
- DIY and prototyping
Not compatible with: 5.5 x 2.5 mm jacks (different inner diameter), center-negative devices (polarity reversal will damage the load), and applications requiring more than 5 A continuous current.

Frequently Asked Questions
Is this cable compatible with my 12 V adapter?
If your adapter or device uses a 5.5 mm outer / 2.1 mm inner DC barrel jack with center-positive polarity at 12 V, this cable is a direct fit. The 5.5 x 2.1 mm form factor is the most common DC barrel-jack standard worldwide and is used by the majority of consumer routers, CCTV cameras, LED strip drivers, and small-appliance adapters.
What is the difference between 20 AWG and a heavier gauge for 12 V DC use?
20 AWG is rated for the 5 A continuous load on this cable with margin. A heavier gauge (lower AWG number, e.g. 18 AWG or 16 AWG) reduces voltage drop on long runs and allows higher current, but is overkill for typical 12 V loads under 5 amps over distances under 2 meters.
Can I cut this cable to a custom length?
Yes. The PVC jacket strips cleanly with a standard wire stripper, and the tinned copper conductor accepts solder, ferrules, or screw-terminal connections. After cutting, verify polarity with a multimeter before powering the load — the red conductor is positive and the black conductor is negative.
How fast does shipping take?
Orders are dispatched from regional fulfillment partners in North America, Europe, and Asia. Typical delivery is 5 to 15 business days depending on destination country, with tracked shipping included. Specific timelines per destination are listed in the Shipping Policy.
How does this pigtail cable compare to others in its category?
Within the DC pigtail-cable category, the meaningful comparison points are conductor gauge, jacket flexibility, and polarity-coded insulation. This product uses tinned copper at 20 AWG, color-coded PVC, and a standardized 5.5 x 2.1 mm jack — the configuration that fits the largest installed base of consumer 12 V devices and drives the lowest return rate within our small-electronics category.
