| Jun 6, 2013 at 1:18 | comment | added | geekman | Thanks! Out of curiosity, why is it that even the cheapest converters on that page are still twice the cost of some cheap wall warts that do the same thing? | |

| Jun 6, 2013 at 0:29 | comment | added | lyndon | I have used the VOF series power supplies (12V 2A version) similar to the ones in the first link for over a year and am very happy with them. They seem to have better specs than a cheap wall wart. I've even accidentally shorted one out, thought I killed it, but it just went into shutdown and came back up after I power cycled it. If you are that cost sensitive, it may be worth looking into DIY'ing your own power supply. | |
