The DC Female Jack Power Connector with Wire (5.5mm x 2.1mm) is a pre-wired, heavy-duty solution for providing power input to your electronic devices. At Electrapac, we recommend this "Pigtail" style connector for technicians and hobbyists who want to avoid soldering small DC pins and prefer the reliability of a factory-molded connection for their battery packs and security systems.

Product Overview

This connector features a standard 5.5mm x 2.1mm female socket on one end and two stripped, tinned wires on the other. The molded PVC housing provides excellent water resistance and physical durability, making it the industry standard for CCTV camera installations and DIY battery enclosures. By using a pre-wired jack, you ensure a solid connection that won't flicker or break under vibration.

Key Features for Electrapac Customers

• Time-Saving "Pigtail" Design: No need to disassemble a plastic shell or solder tiny terminals. Simply use a wire nut, lever nut, or heat-shrink butt connector to join these wires to your circuit.

• Standard Compatibility: Perfectly fits all 5.5 x 2.1mm male plugs, which are the global standard for 12V power adapters, routers, and LED controllers.

• Color-Coded Polarity: Comes with pre-stripped Red (+) and Black (-) wires, drastically reducing the risk of reverse polarity mistakes that could damage your expensive electronics.

• High-Current Copper Core: Unlike cheaper aluminum-core versions, our connectors use multi-strand copper to ensure minimal voltage drop and heat generation, even at higher current loads.

• Molded Strain Relief: The transition between the jack and the wire is reinforced with thick PVC to prevent the internal connections from snapping when the cable is pulled or bent.

Wiring & Installation Guide

Integrating the Electrapac Pre-Wired Female Jack into your project is straightforward:

1. Red Wire: Connect to the Positive (+) terminal of your battery or PCB.

2. Black Wire: Connect to the Negative (-) or Ground (GND) terminal.

3. Insulation: After twisting the wires together, always use Heat Shrink Tubing or high-quality electrical tape to prevent short circuits.

Pro-Tip: If you are building a custom battery pack (like a 3S Li-ion pack), solder this female jack to your BMS (Battery Management System) output. This allows you to charge the battery using a standard 12.6V wall adapter without needing to open the case.

Primary Applications

• CCTV Power Extension: Connecting security cameras to a centralized power distribution box.

• DIY Battery Packs: Adding a charging or output port to 18650 lithium battery projects.

• Arduino & ESP32 Power: Providing a clean DC input for your project enclosures.

• LED Strip Projects: Creating a power entry point for 12V LED strips without soldering directly to the strip.

• Networking Gear: Replacing damaged power input jacks on routers, switches, and modems.
