I bought something that looks pretty much exactly the same.? Be advised, as soon as you put any load on it, the fan will come on.? I just moments ago put a load on mine (a CB radio under TX), and the fan noise increased substantially.? I used the CB to test it as I recall previously using the PS and having it go to 16-18V under load (hence the CB- didn't want to risk my good stuff....).? This time it stayed at 12.8 or so.? YMMV.?
