the 5amp works if it is well made.
the 6amp should be better as it has more over head.
5 x 12 = 60 watts
6 x 12 = 72 watts
this unit pull 40 to 50 watts.
50/60 = 83% just over the 80% rule for running gear 24.7.365
50/72 = 69% well under the 80% rule for running gear 24.7.365
so, based on this feedback, if we'll use a 12V 8A power brick, would it be much more safe? please enlighten me... i saw a power brick on my way home that has this rating. i might consider that as an option.
thanks...
