Our 2.5mm to 2.1mm DC Adapter Cable is the ideal solution for connecting standard 2.1mm power adapters to devices that require a 2.5mm barrel input. Available in lengths ranging from a compact 16cm patch to a long 10M extension, this cable provides maximum flexibility for powering laptops, monitors, and specialized electronics.
Universal 2.5mm Output Plug: Features a 2.5mm (ID) x 5.5mm (OD) male connector, a common standard for high-draw electronics and specific laptop brands.
Standard 2.1mm Input Interface: Equipped with a standard 2.1mm x 5.5mm DC female socket, allowing you to use your existing power bricks with ease.
Ultra-Flexible Length Options: Choose the perfect fit for your setup with lengths of 16cm, 1.5M, 3M, 5M, or 10M.
Durable Molded Strain Relief: Both ends feature reinforced, integrated strain relief to protect internal copper cores from breakage due to bending or pulling.
Heavy-Duty PVC Jacket: Encased in a rugged, matte black PVC housing that resists wear and tear while maintaining excellent flexibility.
Anti-Slip Textured Grip: The female socket is designed with a knurled texture to ensure a firm, secure grip when connecting or disconnecting power.
Connector A (Output): 2.5mm x 5.5mm DC Male Plug.
Connector B (Input): 2.1mm x 5.5mm DC Female Socket.
Available Lengths: 16cm / 1.5M / 3M / 5M / 10M.
Core Material: High-Conductivity Oxygen-Free Copper.
Jacket Material: Impact-Resistant Flexible PVC.
Power Supply Adaptation: Convert a standard 2.1mm power adapter for use with devices like CCTV cameras, LED strips, or monitors that use a 2.5mm port.
Long-Distance Powering: Use the 5M or 10M versions to run power from a central adapter to remote equipment across a room or office.
Laptop & Monitor Leads: Ideal for replacing or extending power cables for specific electronic hardware requiring a 2.5mm inner diameter.
What is the difference between 2.1mm and 2.5mm? While both have the same 5.5mm outer diameter, the 2.5mm version has a slightly larger internal pin hole. This cable bridges that gap, allowing a 2.1mm pin to fit into a 2.5mm device port securely.
Does this cable change the voltage? No. This is a straight-through power cable. It passes the voltage directly from your power supply to your device. Always verify your device's voltage requirements before plugging in.
Is there signal loss on the 10M version? Our long-length versions use high-quality copper cores to minimize voltage drop, but for very high-power devices, we recommend using the shortest length possible to ensure maximum efficiency.
