Need reliable power for your gadgets? This RedFringe 2-pack gives you two 24V 2A 48W power adapters. They take normal wall power (100-240V AC) and convert it to 24V DC, which is what a lot of electronics need. The output jack is 5.5mm x 2.5mm – a super common size. Perfect for powering 5050 or 3528 LED strip lights, 3D printers, CCTV security cameras, LCD monitors, routers, and more. Important: Make sure your device runs on 24V DC (not AC!) and draws 2 amps or less. If it needs more than 2A, this adapter will get damaged. It supplies only what your device needs up to 2A. Each adapter has a 90cm cable. The plug is US style. They work in a wide temp range (-20 to 40°C). Great to have a spare, or to power two devices at once. A solid, basic power solution for your tech projects or security setup.
