In evening backup radio power supply fun and games. of three buck converters delivered from China only two functioned correctly.

Maybe I've just been unfortunate, but it seems that Chinese gear is becoming less and less reliable.....and sometimes just damned dangerous.

Last month I received two super duper 1kw 48v Switched Mode Power Supplies for my generator Inveter project. These supplies have a board mounted switch for 110v or 240v input voltage selection. Lucky I opened the cases to ensure 240v was selected, as a quick glance at the components and construction revealed that the units were not 48v but 1Kw 12v units... That's 83 amps output as opposed to the 20a I had provided for. Not only would the inverter not worked and possibly been damaged, the feed cable would have severely overheated and become a major fire hazard!.. Just in case components were wrongly marked, I checked output voltage and sure enough 12v was being delivered.
