Stable, high-wattage power for demanding devices. This "Used - Like New" switching power supply delivers a regulated 12.0V output with a robust 3.0 Amp (36 Watt) capacity. Because it provides higher amperage, it can safely replace lower-rated 12V adapters (like 12V 1A, 1.5A, or 2A units) without overheating, as your device will only "pull" the current it needs. It features a standard 5.5mm x 2.1mm (compatible with 2.5mm) center-positive barrel jack, making it the universal choice for modern networking and display hardware.
