Whoops. Since Tom invited us to this off topic discussion, my two minor complaints about PowerPoles:
1: No make-first for ground. This is actually alleviated by other Anderson connector styles - in the 15A range they have a make first pin (which breaks the hermaphodicity). And in the big-boy multi hundred amp range they use a secondary make-last set of contacts to authorize application of power by the source.
Without a make first for ground you worry that some flimsy signal ground might be asked to carry 30Amps.
2: Not locking. Well at least we aren't going to be dangling a piece of equipment falling off edge of bench by the power pole.
Despite the above two caveats I don't have anything better. Molex connectors aren't really locking either and the certainly don't last at their rated current when exposed to an automotive or outdoor environment.

Wes, Don,
I am quite surprised at the negative reaction to Anderson Power Pole connectors. I have found them the best DC connector out there. I have used them for a decade or two for all my DC feeds and have never had a problem: in my home lab, my car, even for my laptop charger. They are inexpensive, reliable, genderless (hermaphroditic) and easy to crimp. I use them for my 5V, 12V, 24V, and 48V supplies as well as my DC backup systems.
What on earth are you doing with them that causes them to disconnect? I mean, they are not meant for towing or lifting or rappelling. For critical applications there is a plastic gizmo that keeps them mated; or just use a square or figure 8 knot on the cables.
