Description

This DC bare-end pigtail power wire is a flexible DC power connection cable designed for custom wiring installations, repair projects and equipment modifications. It features a standard 5.5×2.1mm male DC barrel plug on one end and stripped wire leads on the other end, allowing users to solder, crimp or connect the cable directly to terminals, power boards, battery packs, LED drivers and other DC-powered devices. It is widely used in security surveillance, LED lighting, smart home, networking and DIY electronics projects.

The cable is terminated with a 5.5×2.1mm male DC plug, which is compatible with most DC power adapters, CCTV cameras, LED strips, routers and security system equipment. The opposite end is stripped and ready for direct connection, making it suitable for applications where a standard pre-terminated cable cannot meet the required wiring length, connector type or termination method. This bare-end design provides greater flexibility for custom installations and repair work.

Internally, the cable uses two conductors with red and black insulation for easier polarity identification. Red is typically used for positive polarity and black for negative polarity, helping technicians maintain correct DC polarity during installation. Reversed polarity may cause equipment damage, so proper voltage and polarity checking before connection is strongly recommended.

Conductors are made of copper for good conductivity and stable power delivery. The 20AWG version is suitable for general-purpose CCTV cameras, routers, LED strips and low-power DC devices. The 18AWG version is recommended for longer wire runs, higher-power LED strips and applications requiring lower voltage drop. Both versions are designed for low-voltage DC operation and are commonly used in 12V and 24V systems.

The DC plug end is fully molded with strain relief to reduce bending stress at the cable root and prevent internal wire breakage caused by frequent plugging and movement. The outer PVC jacket provides basic abrasion resistance and flexibility for indoor installations and protected outdoor use. For outdoor applications, it is recommended to route the cable through conduit or a weatherproof enclosure.

This DC pigtail wire is widely compatible with CCTV cameras, DVR/NVR systems, LED strips, LED drivers, wireless routers, access control devices, small monitors, 12V fans, battery packs and other DC-powered equipment. Standard lengths include 0.3m, 0.5m, 1m, 2m and 3m. For bulk OEM orders, we support custom connector sizes, wire gauges, lengths, insulation colors, polarity markings and private-label packaging.

FAQ

Q: What is a DC bare-end pigtail power wire used for?

A: It is used for custom DC power wiring, equipment repair, soldering, terminal connection and DIY projects where one end needs to be connected directly to a power board, battery or terminal block.

Q: What does 5.5×2.1mm mean?

A: 5.5mm is the outer diameter of the DC barrel plug, and 2.1mm is the inner pin size. This is one of the most common DC power connector sizes for 12V and 24V devices.

Q: What is the red and black wire for?

A: Red is typically positive and black is typically negative. Always confirm polarity before connecting to avoid reversed polarity damage.

Q: Can I use this for 12V and 24V devices?

A: Yes, it is suitable for low-voltage DC applications including 12V and 24V systems, as long as the current and power requirements are within the cable rating.

Q: What is the difference between 18AWG and 20AWG?

A: 18AWG has a larger conductor cross-section and supports higher current or longer runs with less voltage drop. 20AWG is suitable for general-purpose devices and shorter wiring.

Q: Is this cable waterproof for outdoor use?

A: The standard PVC jacket is suitable for indoor and sheltered outdoor use. For fully exposed outdoor installations, use conduit or a weatherproof enclosure.

Q: Do you support custom orders?

A: Yes, we support custom connector sizes, wire gauges, lengths, insulation colors, polarity markings, logo printing and private-label packaging for bulk OEM orders.
