When a standard connector falls short, our 5.5mm x 2.1mm x 14mm Long-Reach DC Plug provides the extra length required for a secure connection. Featuring a significantly extended 14mm barrel, this plug is specifically designed for devices where the power socket is recessed behind thick plastic housings, waterproof seals, or ruggedized protective cases. No more intermittent power due to a plug that "barely reaches"—this connector ensures a deep, stable seat every time.
Ruggedized Outdoor Gear: Ideal for powering outdoor security cameras or sensors housed in thick, weather-resistant enclosures.
Waterproof Housings: Perfect for devices in specialized cases where the wall thickness prevents a standard 9mm plug from making contact.
Industrial Equipment: Used in heavy-duty machinery where ports are set back for protection against impact or dust.
Custom DIY Enclosures: The go-to choice for hobbyists using 3D-printed or thick-walled project boxes.
14mm Extra-Long Barrel: Provides 5mm of additional length compared to standard plugs, ensuring compatibility with the deepest recessed ports.
Universal 2.1mm Center Pin: Compatible with the industry-standard 5.5 x 2.1mm socket size found on 95% of low-voltage electronics.
Durable Solder Terminals: Features high-quality internal solder buckets designed for a permanent, low-resistance connection to your power cable.
Integrated Strain Relief: Includes a rugged, screw-on plastic shell with a flexible boot to protect against cable fatigue and wire exposure.
Solves Connection Issues: Specifically engineered for "hard to reach" ports that standard chargers cannot power.
High-Conductivity Nickel Plating: Prevents corrosion and maintains signal integrity for sensitive electronics.
Industrial Resilience: Built to withstand frequent mating cycles in demanding environments.
Connector Type: DC Barrel Plug (Male)
Size: 5.5mm (Outer Diameter) x 2.1mm (Inner Pin Hole)
Barrel Length: 14mm (Extra Long)
Will this work if my device only needs a 9mm plug?
Yes. It will function perfectly, but a portion of the metal barrel will remain visible outside the socket. It is electrically safe but may not sit flush.
Can I use this for my laptop?
Only if your laptop uses a 2.1mm pin. Many high-power laptops use a 2.5mm pin. Please check your center pin diameter with a caliper before ordering.
Is the center pin positive?
As a solder-type connector, you determine the polarity. However, Center-Positive is the global standard. Always verify your device requirements before soldering.
