Restore power to your high-performance devices with our 6.3mm x 3.1mm DC Power Plug. This specialized male barrel connector is designed for heavy-duty power applications that require a larger-than-standard interface. Most commonly found on high-wattage power bricks for Toshiba and older HP/Compaq laptops, this solder-type connector allows you to repair broken power leads or create custom high-current power extensions with ease.
Laptop Power Supply Repair: The correct replacement tip for various high-output Toshiba, HP, and Compaq AC adapters.
Industrial Power Interfaces: Used in specialized telecommunications and laboratory equipment requiring a 6.3mm outer diameter.
Custom High-Current Cables: Ideal for creating custom leads for high-wattage 12V–19V DC power supplies.
Radio & Communication Gear: Frequently found in older ham radio power interfaces and specialized audio equipment.
Specialized 6.3mm x 3.1mm Dimensions: Features a 6.3mm outer barrel diameter and a 3.1mm internal pin hole for a secure, wiggle-free connection.
Durable Solder Terminals: High-quality internal solder buckets designed to accommodate thicker gauge wires (up to 16AWG) for high-current loads.
Integrated Strain Relief: Includes a flexible, screw-on plastic boot that protects the solder joints from mechanical stress and cable pulling.
High-Conductivity Nickel Plating: Engineered for low contact resistance and maximum corrosion resistance, ensuring a stable voltage flow.
"Hard-to-Find" Specialist Part: Ensures you don't have to replace an entire expensive power brick just because of a broken connector tip.
Heat-Resistant Insulator: The internal core is rated for high temperatures, preventing melting or pin shifting during the soldering process.
Industrial Resilience: Built for high mating cycles, providing a long-term solution for professional repair shops and DIYers alike.
Connector Type: DC Barrel Plug (Male)
Size: 6.3mm (Outer Diameter) x 3.1mm (Inner Diameter)
Will this fit a standard 5.5mm x 2.1mm socket?
No. This plug is significantly larger. It will not fit into a standard 2.1mm or 2.5mm DC socket. Please measure your port carefully before ordering.
Is this compatible with Toshiba laptops?
Yes. Many older Toshiba Satellite and Tecra models use the 6.3mm x 3.0mm/3.1mm standard. This is the correct repair part for those adapters.
How do I know which terminal is Positive (+)?
The center pin (inner terminal) is usually wired as Positive, and the outer barrel is Negative. However, always use a multimeter to check the polarity of your power source before soldering!
