Assuming that I don't need 45+ amps of 12v or a built in battery charger, is there any reason to use an RV Power Converter over a Meanwell type 12V power supply like the one below? All I'm planning on running off it is 3 single bulb LED lights (most likely not more than 2 of them at a time) and maybe a 12v fan.
