I have a transformer that says it has a 4.5VDC, 400mA output. I was thinking about using it to power this: http://o-like.com/b2b_cpinfo.asp?id=966.
My question is, when I tested the voltage/polarity using a DMM, the voltage measured around 6.7V. Before I was worried that it would've been underpowered (4.5V), but now, I'm worried about blowing it out. So, do you think it would be safe to use this transformer (the circuit inside protects for all this), or no?
