    I have a Mini, a Stream, a cable modem and a router in (virtually) the same place. All need 12 volts so all need wall-warts. For 5 volt devices there are any number of USB power bricks with a single AC cord and multiple DC outputs. Has anyone ever seen or heard of such a device for 12 volt equipment? (DC cabling is another matter but no use looking for that, yet.)

    Sure, it's called a 12vdc power supply. I use them all the time. Add up your amp requirement and get one sized accordingly. There are many plugs available. 2.5mm is the most common. I usually make my own cords with plugs cut to length.

    I share your disdain for wall warts.
    But, have not thought of using a single source 12v power supply.
    I suppose a repurposed PC power supply could work.
    And, thinking about it briefly, it would be relatively easy project.
    If you had the necessary DIY skills.

    This sounds like the plan... Are you referring to a DIY project or plug & play?
    What power supply do you use?
    Or.
    Post a link maybe?
    Photos would be great if available.

    After posting my question I continued my search for a solution. So far, the closest "ready-made" product I have found is 12 vdc power supplies intended for use with security cameras. They have a single DC output split into four to eight male plugs but I'll need to do more research into my equipment to see what plugs they require. And, I need to find some extension cables for the DC output as the split cables on the power supply are rather short.

    (Now, if some one would combine 12 vdc and 5 vdc outpit into a single box...)

    After posting I too continued to search for an answer.
    I found some interesting opinions here: http://arstechnica.com/civis/viewtopic.php?f=53&t=1293109
    Within that link was this: https://www.amazon.com/FireKingdom-...p/B00R70YRR8?ie=UTF8&pldnSite=1&redirect=true which could address YOUR specific concern; a cluster of wall warts powering several devices.
    One problem using a single source, would be if one or more of the devices needed to be moved.

    I feel your pain. I have an 802.3af compatible switch (Power Over Ethernet) and for Ethernet devices that require 12volts such as the Mini I found that these work well http://www.ebay.com/itm/322197456876 and moves the power supply to my switch.

    Of course these only support 10/100Mb/s but many devices either don't support 1Gb/s or realistically don't need it.

    Isn't that what was suggested in the post before yours, by Teeps? PC Power supplies offer 12V and 5V outputs.

    Yes, but note his caution: "If you had the necessary DIY skills..."

    My degree from Father Guido Sarducci's 5-Minute University leaves me lacking in such. I was hoping someone had done the work for me with a stylish power block with some 5 vdc USB ports and some 12 vdc 5.5/2.1mm barrel ports (cables extra).

    My EE education proceeds apace.

    (I added things up and I have two 2-amp and two 1-amp devices so a 12 volt 10 amp switched supply will, I hope, run under-stressed and cool.)

    Fair enough. I'm just glad you're old enough to know who Father Guido Sarducci is! :p

    This DC power supply looks useful: http://www.ebay.com/itm/Audiopipe-DVP512-Nippon-110V-Power-Supply/400749157877?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D37471%26meid%3D8dd620ca66714fa59317a4cf5d7eb40c%26pid%3D100005%26rk%3D1%26rkt%3D6%26sd%3D291820625132
    You would have to create a custom cable but that should be relatively straight forward.

    Or you could keep the wall warts and plug them into this: https://www.amazon.com/Cables-Go-29803-Power-Splitter/dp/B000083KIH/ref=sr_1_2?ie=UTF8&qid=1469809236&sr=8-2&keywords=1+to+5+power+cord+splitter

    I add caveats so as to not waste other's time.
    Or, sometimes a man just wants a fish.

    Far as Father Guido Sarducci; never got his humor...

    No matter how you address it, consolidating 12 volt power supply MUST be a DIY project. But there's advantages to 'warts', opposed to 'line power' cords
    And if you have 'transformer' warts, ditch those. Very inefficient, compared to switchers.

    I'm concerned not only with the number of them on my closet electronics shelf but with power outages. I use a Belkin 12v UPS (orig for UVerse phone) to power my cable modem and router so as to maintain some 'net Wi-Fi connection for phones during loss of power (and to stop them rebooting during a glitch). I live in poor 4g coverage area

    If, as in the case of my network router, the wart cord ends in a non-standard plug other than 2.5, youre going to have to do some wire splicing.
    Otherwise I recommend using what we used to call 'fan-out', now called 'splitter' cables as noted above made for cctv power distribution.
    All the options above are good.

    If you are in a media closet or something like that, check out ebay and search for "12v distribution box". They make them for anything from 4 devices on up to about 18 devices.
    Its just a small metal enclosure you would mount on the wall. It has a door on the front and screw terminals inside. You just add pigtails for however many devices you need.
    I've seen some kits that include the pigtails also.
    Also look at "12v cctv connectors" on ebay. I like the ones with the little green screw terminals.
