Stop worrying about mismatched power tips with our Universal 5.5mm DC Power Plug. This innovative "Hybrid" connector is engineered with flexible internal leaf-spring contacts. While standard plugs are fixed to one size, this plug expands and contracts to provide a snug, reliable fit on both 2.1mm and 2.5mm center pins. It’s the perfect all-in-one solution for technicians, hobbyists, and anyone maintaining a variety of 12V–24V electronic equipment.
Universal Test Leads: Create a single power cable for your workbench that can interface with almost any 5.5mm DC-enabled device.
IT & Networking: Perfect for powering routers, modems, and switches, which often vary between 2.1mm and 2.5mm standards.
Laptop & Monitor Repair: Ideal for high-wattage power bricks that typically require the 2.5mm pin, as well as standard displays using 2.1mm.
Field Service Kits: A "must-have" spare part for field technicians who need to replace power tips on the go without carrying bulky assortments.
Intelligent Spring-Loaded Contact: The internal "tuning fork" design grips 2.1mm pins tightly while safely expanding to accommodate 2.5mm pins without losing tension.
Professional Solder Terminals: High-conductivity internal solder buckets designed for quick and secure attachment of 16–24 AWG power wires.
Rugged Strain Relief: Includes a screw-on ABS housing and a flexible rubber boot to protect the internal solder joints from mechanical stress and cable fatigue.
Nickel-Plated Performance: Ensures maximum corrosion resistance and low-resistance electrical contact for stable power delivery up to 24V.
Inventory Efficiency: Reduces the number of individual parts you need to stock; one plug does the work of two!
Heat-Resistant Core: The high-quality internal insulator remains stable during soldering, preventing pin misalignment.
Guaranteed "No-Wiggle" Connection: Provides a firmer grip than cheap plastic plugs, preventing intermittent power loss or sparking.
Connector Type: Universal DC Barrel Plug (Male)
Size: 5.5mm (Outer Diameter) x 2.1mm/2.5mm (Universal Inner)
How can one plug fit two different pin sizes?
Unlike a solid metal tube, the interior of this plug has spring-tensioned metal leaves. They remain narrow for a 2.1mm pin but are pushed outward (while maintaining pressure) when inserted onto a 2.5mm pin.
Is it safe for high-current devices?
Yes. The spring-loaded contacts actually provide more surface area contact than a standard "fixed" plug, making it very efficient for higher amperage loads.
Does it come with a yellow tip?
Some manufacturers use yellow or blue tips to signify 2.5mm. This universal model is typically Black to match all standard equipment visually, though the functionality is superior to fixed-color tips.
