I know...it's been asked a MILLION times before - but I need help lol
I have an LG incubator someone gave me as a "thank you" - brand new but absolute base model right? I want to add a fan....I have a little pc fan I bought to make my own 'bator and never did. It states on the packaging: Rated voltage 12v Started voltage 6V
Okay...I have 3 little adapter cord things I could splice in....one is 3v, the other says 5v and lastly I have one that is 9V.....
Will any of these 3 work? Or should I look for a 6V specific one at Radio Shack maybe??
I think I have the basics down - just not sure if one of these 3 power cords I've been hanging on to for this purpose would work....
Thanks in advance!
