USB to 3mm DC Cable

The USB to 3mm DC Cable is a convenient power cable designed to supply 5V DC power from a standard USB Type-A port to electronic devices equipped with a 3mm DC barrel jack. It provides a simple and reliable solution for powering low-power electronics directly from USB sources such as power banks, laptops, desktop computers, USB wall adapters, and car USB chargers, eliminating the need for dedicated power adapters in many applications.

Featuring a USB Type-A male connector on one end and a 3mm DC barrel plug on the other, this cable delivers stable and efficient power for compatible devices. Constructed with high-quality copper conductors and durable insulation, it ensures excellent electrical conductivity, low power loss, and long-lasting performance. Its flexible outer jacket provides resistance to bending and daily wear, making it suitable for both portable and permanent installations.

The USB to 3mm DC Cable is widely used for powering routers, mini fans, LED lights, portable speakers, CCTV accessories, development boards, Arduino projects, Raspberry Pi accessories, IoT devices, battery-powered electronics, embedded systems, and DIY electronics projects. Its plug-and-play design allows quick and hassle-free connection without requiring additional tools or complex wiring.

Compact, lightweight, and easy to carry, this cable is ideal for students, hobbyists, technicians, and professional engineers who need a reliable USB-powered solution for prototypes, repairs, educational experiments, and portable electronic devices.

Note: Ensure that your device is designed to operate on 5V DC and uses a 3mm DC barrel connector before connecting the cable.
