Review on Universal Regulated Switching Converter - SUPERNIGHT 12V 30A DC Power Supply Driver Adapter for 3D Printer, CCTV, Radio, Computer Project, Industrial Automation, LED Strip - 360W AC 110V/220V Transformer by James Broome

This 30Amp adapter should be the best deal you can find for powering FM hams around your home. I suggest you take some time to take it apart and check the soldering work, make sure all points are touching. Helps wipe away the factory thick heatsink paste smeared on the aluminum walls and replace it with something more thermally conductive (which is pretty much it) if you want the device to run cooler and last longer. Cheap CPU lube works great. I used a spare computer cable with one end cut off, looked up the wire colors on your favorite search engine, or tested them with a voltmeter to get the correct ground, common, and hot wires. The soldered spatulas for the screw part keep it nice and clean - and arguably safer than loosely braided wires crumpled in the terminal block. You can tighten them up pretty well without fear of breaking the connecting rod. Thumbs up!
