From: "donjohnston" The Cessna I've had for 15 years has a 24v power jack and I've never had a problem with passengers connecting anything to it. Partly because I don't let my passengers connect things to my airplane without asking first (and if they didn't ask, they deserve what they get). :D And secondly, it's already in use. So can someone second that there is no difference in the construction of one of these 12v connectors?

Im a novice at electrical circuit stuff >as you can tell but, eager to learn and willing to ask questions. > >And yes, I agree, spoilers is a more accurate >term for these lift disturbing devices Ill correct that. It's an understandably mixed bag for terminology . . . Forces exerted by drag go up with square of speed so extending these little critters into the slip stream at cruise will, no doubt, exert substantial drag during a flight condition where lift is at maximum (attack angle low). During approach to landing, airspeed is perhaps 1/3 that of high speed descent and the wing is working harder at a higher attack angle. The only two times I experienced the behavior of this system was in Mooney's on approach. Once at Kerrville with a factory test pilot, the other at Wichita in a friend's airplane. In both cases I was encouraged to toggle the boards up and down while watching the effects on rate of descent. The extending the boards had no observable effects on airspeed or angle of attack but a profound effect on rate of descent. Hence they were behaving more as modifiers of lift than as dissipators of kinetic energy . . . i.e. spoilers I think there is a valid argument to be made for both behaviors dependent upon the flight airplane's flight condition. I was at Cessna in their Tech Pubs department when Bill Thompson (founder of Precise Flight) was head of flight test. He was partners with my teacher, friend and mentor of more than 40 years (Ken Razak) in a nice old C-195. It was my offer to install a Cessna surplus ADF-300 in the 195 that introduced me to Ken and launched a career very rich in opportunities to learn. I owe much to those two gentlemen . . .

To answer your original question, the lighter jack you mentioned should work with 24V. Typically voltage ratings are either (1) for safety reasons, where it is easy to stick a finger in and get a shock, or (2) for dielectric withstanding/arcing. 12 to 24V isn't enough to trigger either restriction. While alternatives have been suggested, fuse it properly and you'll be fine. -Jeff- On Fri, Mar 7, 2014 at 9:46 AM, donjohnston wrote: > don@velocity-xl.com> > > > user9253 wrote: > > How about installing two DC power outlets, one for 24 volts and one for > 12 volts?
