Upgrade your device’s power entry with our 5.5mm x 2.5mm DC Power Socket. This female barrel jack is the preferred choice for high-wattage electronics that require more current than standard 2.1mm jacks can provide. Often found on laptop power bricks, high-output LED drivers, and industrial chargers, this socket ensures a secure, low-resistance connection for your most demanding projects.
High-Current DIY Projects: The go-to socket for high-power motor controllers, battery charging stations, and custom 12V/24V power banks.
Equipment Repair: A direct replacement for damaged 2.5mm power ports on laptops, monitors, and networking hardware.
Pro Audio & Amplifiers: Ideal for powering high-fidelity Class-D amplifiers that require a stable, high-amperage DC supply.
Industrial Power Panels: Perfect for mounting on control boxes that interface with external high-output AC/DC adapters.
Precision 2.5mm Center Pin: Specifically engineered to fit the 5.5 x 2.5mm "Type B" DC plug, providing a tighter grip for high-current stability.
Rugged Panel Mount Design: Features a threaded barrel and hex nut for professional mounting through enclosures up to 4mm thick.
Heat-Resistant Solder Lugs: Equipped with heavy-duty terminals that handle soldering heat and high-gauge wire with ease.
Vibration-Resistant Connection: Internal leaf-spring contacts maintain constant pressure on the male plug to prevent sparking or power dropouts.
Higher Amperage Rating: Typically rated for 5A to 10A, making it safer for power-hungry devices compared to standard 2.1mm sockets.
Industrial Grade Insulation: Built with UL-rated thermoplastics to ensure long-term durability in both indoor and outdoor enclosures.
Universal Standard: Compatible with a wide range of universal high-output power adapters.
Connector Size: 5.5mm (Outer Diameter) x 2.5mm (Inner Pin)
Mounting: Panel Mount (Threaded)
Can I use my 2.1mm power adapter in this 2.5mm socket?
No. While a 2.1mm plug will physically slide into the 5.5mm hole, the inner hole of the plug is too small to fit over the 2.5mm pin. Never force it, as this can damage the pin.
What happens if I use a 2.5mm plug in a 2.1mm socket?
It will fit loosely and likely won't make an electrical connection, or it will cause intermittent power loss. Always match your plug and socket sizes for safety.
Is this socket "Center Positive"?
Most DC sockets are non-polarized until you solder them. However, the center pin (the shorter lug) is traditionally wired as Positive (+). Always check your device's polarity requirements!
