Ensure your electronics receive a steady, high-quality power supply with our 9V 3A AC-DC Adaptor. Specifically engineered for high-demand devices, this power brick provides a stable 27W output. Equipped with the industry-standard 2.1mm DC barrel jack and a generous 1.5-meter (1.5m) cable, it offers the flexibility and reach needed for professional, home, or industrial setups.
Networking Equipment: Ideal for high-performance routers, modems, and network switches requiring a stable 9V input.
Audio & Video Gear: Perfect for powering guitar pedals, portable amplifiers, and digital effects processors.
LED Lighting: High enough amperage to drive short runs of 9V LED strips or decorative lighting displays.
DIY Electronics: A reliable power source for Arduino projects, robotics, and microcontroller kits.
High Current Output: The 3A (3000mA) capacity means it can comfortably handle devices that draw high power without overheating or voltage drops.
Standard 2.1mm x 5.5mm Jack: Features the most common DC connector size, ensuring compatibility with a vast range of consumer electronics.
Extra Reach: The 1.5m cable provides significant freedom for cable management, reaching from floor outlets to desk-height equipment with ease.
Advanced Protection: Built-in safeguards against over-voltage, over-current, and short circuits to protect your expensive hardware.
Clean Power Signal: Designed with internal filtering to minimize "hum" and electrical noise, which is critical for audio and sensitive data equipment.
Efficiency Focused: Meets modern energy standards to reduce power consumption during standby mode.
Industrial Grade Build: The rugged black housing and reinforced strain relief on the cable ensure long-term durability under daily use.
Output: 9V DC 3A (27W Max)
Connector: 2.1mm Inner Diameter / 5.5mm Outer Diameter
Cable Length: 1.5 Meters (1.5m)
Polarity: Center Positive (+)
Can I use this for a device that only needs 1A?
Yes. Amperage is "pulled" by the device. As long as the voltage is 9V, a 3A adaptor will safely power a device needing 1A, 2A, or 3A.
Will this fit my 2.5mm port?
While a 2.1mm plug might fit into a 2.5mm socket, the connection may be loose and unstable. Please verify your device's port size for the best performance.
Is this "Center Positive"?
Yes, this adaptor is standard center-positive. Always double-check your device's polarity symbol (diagram with a dot and a ring) before plugging in.
