Eliminate connection dropouts on your heavy-duty equipment with our 5.5mm x 2.5mm x 14mm Long-Reach DC Plug. Featuring an extended 14mm barrel length, this plug is specifically engineered for high-current devices where the power socket is recessed deep within a thick-walled or ruggedized housing. While standard 9mm plugs might struggle to seat properly, this "Long Type" connector ensures a full, stable electrical contact every time.
Rugged High-Power Laptops: Ideal for specialized industrial or gaming laptops that utilize the 2.5mm pin and have reinforced protective casings.
Industrial Enclosures: Perfect for control boxes or outdoor machinery where the power port is set back behind a weather-seal or thick panel.
High-Wattage DIY Projects: The go-to choice for custom 12V/24V power banks and high-output LED drivers using thick project boxes.
Laboratory Equipment: Frequently required for specialized diagnostic tools that feature recessed power interfaces for safety and protection.
14mm Extended Barrel: Provides 5mm of extra length compared to standard plugs, making it the only solution for deeply recessed "Type B" sockets.
Large 2.5mm Center Pin Compatibility: Precision-molded to fit 5.5 x 2.5mm sockets, offering a higher current-carrying capacity than standard 2.1mm variants.
Heavy-Duty Solder Buckets: Features robust internal terminals that can comfortably accommodate 16-18 AWG wires for high-amperage applications.
Professional Strain Relief: Includes a rugged, screw-on plastic housing with a flexible boot to protect against cable fatigue and wire exposure.
Solves "Short-Plug" Issues: Specifically designed for hardware that standard universal adapters simply cannot reach.
High-Conductivity Contacts: Nickel-plated brass construction ensures a low-resistance connection, critical for high-wattage power delivery.
Heat-Resistant Insulator: The internal core stays rigid during soldering, maintaining perfect pin alignment for a smooth fit.
Connector Type: DC Barrel Plug (Male)
Size: 5.5mm (Outer) x 2.5mm (Inner Pin Hole)
Barrel Length: 14mm (Extra Long)
Will this fit into a 2.1mm socket?
No. While the outer 5.5mm diameter is the same, the 2.5mm inner hole is too large for a 2.1mm pin, leading to a loose, sparking, or non-existent connection.
Why do I need a 14mm length?
Standard 9mm plugs often cannot penetrate the outer shell of ruggedized or waterproof equipment. If your device charger "clicks" but the power keeps cutting out, you likely need this 14mm version.
Is it easy to solder?
Yes. The internal terminals are wide enough for hobbyists and professionals alike. We recommend using a small amount of flux for the best results with thicker high-current wires.
