Right Tool for the Job.
I use barrel connectors when I want the cord to come out when the unit falls off the shelf rather than dangle by the power cable.
Locking Molex, or, far better, locking AMP connections when I want the unit to hang by the cord when necessary.
We've gone to 9 pin circular locking AMP connectors for rotors on our 2x /year ham radio contest set up on the mountain (take a look for W2SZ / MGEF). Waterproof (not water tight), sturdy, impossible to misalign. And 40' of cable can hang from one for a few minutes if need be.

Heh, I was thinking just that when I typed it. They're almost inverted, the
pegs are on the plug and the slots are on the socket, the ones I've seen
aren't spiral slots, you have to fully engage the plug before you twist.
I like PowerPoles, I like barrel connections, as with so many things it's
all about the application, choose the one that works for you.

Locking barrel connectors...
Aren't those called BNCs? ;)
In one of my other lives, I see Power Poles used in a very life critical
application. They are used to connect pads to Automatic External
Defibrillators. In that application, the two poles (15A, red & white) are
glued together rather than using the roll pin.

Of course they're not great for applications that need a decent amount of
current and other disadvantages as noted elsewhere.

Actually, I read it with interest. I am designing quite a bit of
electronics. A lot of it is single use, then "throw-away" these
days so long running times are not that much of an issue.
But selecting the right power connector is always a problem
I face. I often choose the 5.5x2.5mm barrel plugs, as they are
quite common on power supplies, but they are kind of suboptimal
when it comes to retentiony The Kycon 4-pole plug is slightly
better, but every and each power supply has a different pinout,
which means that I either need to design it for a specific power
supply or add 8 diodes to get the polarity right.
I pondered a couple of times to use Molex Micro-fit connectors,
as they are cheap, locking and available in almost any number of
poles. The current and voltage rating hare high enough for almost
all needs (but not enough for 240V mains, even if it's rated 300V!).
And incidentally the crimping tool doesn't cost an arm and a leg.
But it's not really a connector one wants to use to power a device
in a proper housing.
Reading on what other people are using and what advantages/disadvantages
the different power plugs have is quite interesting for me.
So, please keep it comming!

Ooh, I forgot the Neutrik range, haven't used those for years.

NL2 etc 40A
They typically run about $3 per connector. I use them on high power
Solid State amps. (VHF and up)

Hi,
The Powerkon variant, which does not mate with Speakon, is what is good
for AC, and found use in the medicine world, as it does not
self-disconnect like IEC-outlets tend to do (yeah, I know about securing
them and I've seen it missused many times but I made sure we have such
securing on our products).
Speakon for power would however be useful for DC.
It used to be that speakers where connected using the XLR range of
connectors (not only the 3 pin XLR connector, but larger sized
variants). Those connectors can handle power and current nicely too, but
there can be better choices and that's where the Speakon comes in for
the speaker-feed, which got much handier.
Cheers,
Magnus - former PA-system engineer

Neutrik make a variant specifically created for power connections instead
of speaker connections. I think they are essentially the same style
design but with different color coding to make them stand out from speaker
connections. I don't know if the contact plating may be different, or the
spacing different so it can handle higher voltages. Ground mates first
before the two power pins (three pin instead of the four pin Speakon). UL
listed for up to 250V AC.

Hi,
Not horribly expensive. Military circular stuff can really burn money
for you. In that context, the Neutrik stuff is fairly cheap and for many
purposes good enough.

Speakon and Powercon cannot mate. This is intentional, so you don't feed
your speaker 240 VAC which would burn the speaker up in most cases.
Same basic ideas thought, but re-applied.

For amateur radio use I've never perceived power poles as offering enough of an advantage over most other power connectors to make me willing to change my other connectors for power poles. I do own some equipment that came with factory installed power pole connectors and I'm generally ok with how they work. Some other amateur radio operators have expressed surprise at my extensive use of non power pole connectors and the use of power poles does seem common in the amateur radio world.
For time nuts and amateur radio use I've been quite happy with the multi pin circular "cannon" style connectors. That would be my typical choice for a "high end" power connector for my various hobbies. At the "low end" I'm happy with two pin "trailer" style connectors but in my experience they are generally only available in "pig tail" form. Both the "cannon" style and "trailer" style connectors are readily available to me as "over the counter" items which plays a major role in my affinity towards them.
Where I used to work "Deutch" connectors were very popular and those are also available to me as an "over the counter" item. I expect I'll start using those at some point as well and will probably switch out the bulk of my "trailer" style connectors for Detch connectors.
I can also see some merit in using XLR style connectors in some applications. I strongly dislike the use of "phono plugs" and PL259 connectors for power supply applications.
All the best

Hi Tom,
I said I use PPs but I don't really like them. If you use a pair as a cable splice then yes, you can tie them together, but in the specific case I referred to, the connection on Elecraft radios, the mate is sticking out the back of a panel and it's impossible to knot the cable or use a zip tie. I am certainly not the only one who has had issues with this. And lest I be called an idiot, this is with a factory assembled and supplied pigtail.

Wes

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.
