Bridge the power gap for your high-draw devices with our 5.5mm x 2.5mm DC Power Plug. Featuring a standard 9mm barrel length, this plug is specifically designed for the "Type B" DC standard, which uses a larger 2.5mm center pin. This is the critical connector for high-wattage equipment like gaming laptops, high-output LED arrays, and industrial charging systems where a standard 2.1mm plug simply won't fit or handle the load.
High-Wattage Laptop Repair: The correct replacement tip for many Toshiba, Fujitsu, and Lenovo power bricks, as well as universal high-output AC adapters.
High-Power LED Projects: Perfect for 12V or 24V LED strip systems that pull more than 5A of current.
Industrial Controllers: Frequently used as the power interface for PLCs, motor drivers, and automation hardware.
Audio Amplifiers: Ideal for custom power leads for high-fidelity Class-D amplifiers and studio equipment.
Specialized 2.5mm Center Pin: Precision-engineered to fit 5.5 x 2.5mm sockets securely, providing a high-surface-area connection to minimize resistance.
Heavy-Duty Solder Terminals: Features robust internal solder buckets that can accommodate thicker 16-18 AWG wires for high-current delivery.
Reinforced Strain Relief: Includes a rugged, screw-on plastic shell with a flexible boot to protect your wiring from mechanical stress and frequent handling.
High-Conductivity Nickel Plating: Ensures an oxidation-free, stable electrical path even in demanding industrial environments.
High-Amperage Safety: Rated for higher current loads (typically up to 5A–10A) compared to the thinner 2.1mm variants.
Heat-Resistant Insulator: The internal PBT core maintains its integrity during high-heat soldering, ensuring the center pin stays perfectly aligned.
Industrial Resilience: A dependable choice for professional repair shops and mission-critical DIY builds.
Connector Type: DC Barrel Plug (Male)
Size: 5.5mm (Outer Diameter) x 2.5mm (Inner Pin Hole)
Barrel Length: 9mm
Will this fit my Arduino?
No. Standard Arduino boards use the 2.1mm pin size. This 2.5mm plug will be too loose and will not provide power. Always verify your device's pin size before ordering.
How do I identify it's a 2.5mm plug?
While they look identical to 2.1mm plugs, 2.5mm plugs often feature a Yellow or Blue insulator ring at the tip (though this is not a universal rule). Measuring with a digital caliper is the only 100% accurate way.
Is 9mm long enough?
9mm is the standard length. However, if your device has a deeply recessed port (like some ruggedized outdoor equipment), you may require a 12mm or 14mm "Long-Reach" version.
