Transformer overload

I'm not sure at the moment of what the solution is to the ever increasing entropy surrounding the growing presence of rats nests of cables, wires, and power cords, but one place I'd start is with the powerstrip plugs and transformers. Every little consumer device now seems to need to be plugged in. These things invariably run on DC and hence require a transformer. Transformers are usually not placed within the device itself. Instead it's a big, sometimes weighty, box you have to plug into the wall or powerstrip socket. When you have several of these things there's just no room to plug them all in. You have to get special spacious power strips that grant room for multiple transformers or perphaps even specialty items. In most cases you end up with a bulk of cords, plugs, and transformers clumped up on the floor or on the wall.

Well, there's a large class of devices out there that are typically small, require only 12 volts of DC or less, and don't need the amperage of a vacuum cleaner. Such devices typically come with their own power transformer with a little mini-jack looking plug that cleanly slides into the device. It is the little mini-jack that is of interest to me. Wouldn't it be nice if along with the ubiquitous 2-3 pronged wall socket, there were DC power strips of these little mini-jacks. No need for 5-10 big transformers elbowing each other for space, just a simple little box with an array of mini-jacks supplying modest transformed electricity to the devices via simple non-bulky cords.

Basically, leave the pronged wall sockets to the big hungry power consuming items like TVs, vacuums, kitchen appliances, and such; but make a second standard set of more numerous socket arrays for the smaller and power modest devices like cordless phones, ethernet routers, portable music players, mobile phones, low power vanity or ambiance lights, electric razors, etc. etc. etc. Of course they'd all need to standardize on the same mini-plug jack (never understood why there are so many pitches to these things, ever see those Radio Shack adaptors with the 20 differently sized tips?) and perhaps even the same output voltage. Heck if it were truly standard, only one type of power cord would be needed, they'd be available anywhere, and you may not even need more than a few.

I just imagine a only-very-slightly more convenient world where I do not need to carry around bulky transformers for all of my portable devices on trips or I didn't have to plug my phone in the far room with the free wall socket. Yes a ubiquitous standard would be nice. But as the oxymoronical saying goes "the good thing about standards is there are so many of them."
