DC power sockets are designed for direct current (DC) electrical connections, widely used in electronics, automotive systems, and industrial equipment. Key details include: Basic Structure and Features Interface Types ◦ Barrel Jack: Most common (e.g., 3.5mm/5.5mm outer diameter for routers, cameras).◦ Aviation Connectors: Industrial-grade waterproof design with screw locking (e.g., GX16-3 pin).◦ USB Type-C: Supports bidirectional power delivery and fast charging (PD/QC). ◦ Cigarette Lighter Sockets: For 12V/24V automotive power. Core Parameters ◦ Voltage: 5V, 9V, 12V, 24V (must match device requirements).◦ Current: 0.5A–10A+ (high-current models require enhanced heat dissipation).

Table of Contents Walk through any electronics store, peek behind any desk, or open up any tinkerer’s parts bin, and you’ll find them: DC barrel jack connectors. These simple, cylindrical connectors are the primary way millions of devices—from internet routers and guitar pedals to LED lights and older laptops—receive their power. Despite the modern dominance of USB, the humble DC barrel connector remains a workhorse in the industry. It’s cheap, robust, and capable of handling significant power. However, it also carries a legacy of confusing standards that has frustrated consumers
