Repair, customize, and build with confidence using our professional-grade DC Male Plug Connectors. These solder-type barrel jacks are the essential choice for anyone looking to create custom power leads, repair broken AC adapter tips, or build high-quality DC extensions. Designed with a rugged screw-on housing and integrated strain relief, these plugs offer a "factory-finish" look and industrial-strength durability for all your low-voltage applications.
Our DC Male Plugs are available in a full range of industry-standard sizes to fit everything from micro-electronics to high-wattage hardware:
5.5mm x 2.1mm: The standard for Arduino, CCTV cameras, and 12V LED strips.
5.5mm x 2.5mm: High-current version for laptops, monitors, and large power banks.
3.5mm / 4.0mm Series: Perfect for netbooks, tablets, and portable digital audio gear.
Specialized Sizes: Includes 6.3mm, 2.35mm, and long-reach 14mm barrels for recessed ports.
Easy-to-Solder Terminals: Features wide internal solder buckets that accept a variety of wire gauges (16AWG to 28AWG), ensuring a permanent and low-resistance bond.
Rugged Strain Relief Boot: The screw-on ABS housing includes a flexible, tapered boot that prevents cable kinking and protects the internal solder joints from mechanical stress.
High-Conductivity Nickel Plating: Engineered for maximum oxidation resistance, providing stable power delivery for 5V, 12V, 19V, and 24V DC systems.
Heat-Resistant Insulator: The internal PBT core is designed to withstand the heat of professional soldering without warping or melting.
Professional Aesthetic: Give your DIY projects a clean, finished look that rivals original manufacturer cables.
Secure Mechanical Fit: Precision-machined barrels ensure a tight "click" into female sockets, preventing accidental power drops.
Industrial Durability: Rated for thousands of mating cycles, making them ideal for both static installations and portable gear.
How do I know which size I need?
The most accurate way is to use a digital caliper. If you don't have one, check the label on your device’s original power adapter or look up the device model's "DC Jack size."
Which terminal is Positive?
For the vast majority of modern electronics, the inner pin (center) is Positive (+) and the outer barrel is Negative (-). Always verify your device's polarity symbol (#) before soldering!
Can I reuse the housing?
Yes! Our housings are screw-on, meaning you can open them up to re-solder or check connections without destroying the plug.
