Quick Overview
The DIYables 5.5 x 2.1mm Female DC Jack to 2-Pin Spring Terminal Block Adapter is a convenient power connection solution that eliminates the need for soldering or screw terminals. This quick-connect adapter converts a standard 5.5 x 2.1mm female DC barrel jack into a press-type 2-pin spring terminal block, allowing you to easily connect bare wires with a simple press-and-insert action. Rated for 3–24V DC operation with up to 8A current capacity (8A at 12V or 4A at 24V), it supports up to 100W of power transfer and is perfect for Arduino, ESP32, ESP8266, and Raspberry Pi power supply connections.
This adapter features a durable flame-retardant construction with PVC insulation and a red-gray PC terminal housing for safety and heat resistance. The press-type spring design ensures a secure, reliable connection without any tools, and the adapter is rated for 6,000 plug and unplug cycles for long-term durability. Each pack includes 5 adapters, providing excellent value for multiple projects or installations. The compact design maintains a professional appearance while simplifying power distribution in electronics projects.
Ideal for LED strip lighting installations, CCTV camera power connections, cooling fan wiring, and general DC power distribution in Arduino, ESP32, ESP8266, and Raspberry Pi projects. Perfect for makers who need a quick, reliable way to connect power supplies to terminal blocks without soldering, or for converting existing DC jack power supplies to work with screw-free terminal connections. Great for prototyping, permanent installations, and any application requiring tool-free, reversible power connections.
