This is a USB to DC 5.5mm x 2.1mm Barrel Jack Power Cable, an essential adapter cord designed to draw low-voltage electricity directly from standard USB ports to run standalone electronic devices. It features a universal male USB Type-A plug on one end and an industry-standard male DC barrel plug with a 5.5mm outer diameter and a 2.1mm inner pin hole on the other. It acts as an easy power supply bypass, turning power banks, phone chargers, or laptop ports into convenient hardware power sources.
The image shows a USB Type-A to DC 5.5mm x 2.1mm Male Barrel Plug Power Cable, a specialized connection cord designed to harvest low-voltage direct current (DC) from standard USB interfaces to drive standalone electronic devices.
Core Architecture & Sizing
- Interface Transformation: Adapts a universal rectangular male USB Type-A port into a traditional cylindrical male DC barrel plug.
- Industry-Standard Barrel Geometry: Outfitted with a standard barrel termination featuring a 5.5mm outer diameter (OD) and a 2.1mm inner pin hole diameter (ID).
- Molded Strain Relief Boots: Engineered with flexible, ribbed PVC sleeves at both connector junction points to protect internal wire cores from stress fractures during heavy use or tight bends.
Technical Performance Attributes
- Native 5V Power Delivery: Routes a stable 5V DC power line directly from standard USB power supplies, computers, or portable power banks along the length of the cable jacket.
- Flexible Copper Core: Built with high-grade, flexible internal copper conductors insulated within a durable matte-black PVC outer jacket.
- Universal Charging Source Bridge: Replaces bulky, specialized wall-wart power adapters by allowing common USB accessories to act as the primary power source for your electronics.
Target Applications
- Microcontroller Development Boards: Delivering steady, regulated 5V power directly to the physical barrel jack ports of an Arduino Uno, Mega, or external breadboard power modules.
- Network & Communication Hardware: Backing up and powering standard 5V networking electronics like Wi-Fi routers, network switches, modems, and smart home hubs during power outages using a standard power bank.
- Desktop & Household Accessories: Supplying reliable operating current to small USB-driven appliances including mini desk fans, LED desktop clocks, Bluetooth speakers, and decorative single-color LED light strips.
