I run the wally world adapto from 9.6 v rc batts with absolutly no problems... I don't have a part number but it was the bigger of the two available (2000 mah I think)

I made a call to the supplier/manuf of the car adapter I bought for this purpose and he said that the adaptor will step down voltages as long as there was at least a 3 volt diferential between the source and the output desired. This is why Matt's experience is working WNP (with no problems).
I got a PM about this business and am still wondering why all the bother with ext. pwr for the JB3? By now most of us have two of the things, with both batts and between the two... who can't run 12hrs? What am I missing? Or am I just missing the fun of the hack I suppose if the batt supply does dry up one may need this option...
Carry on.
the main objective of the VR-JBox is to have multiple (and desired) voltage outputs so i can run various equipment and to minimize the size of the power supply.
personally, i don't open tape much. but when i do, i find it cumbersome to carry different power supply for my dats, pre, adc, etc. so if i can carry a single input voltage source, let's say 12v or 9.6v, and can have various output voltages like 4.5v, 6v and 7.5v then i'm all for it.
jb3's operating voltage range seem to be very narrow from what i've seen, and the best way (imho) to remedy that is via a regulated voltage supply.
...and diy projects are kinda fun too...
