The more you look at the writhing orgy of plugs in the world, the sillier it seems. If you buy a phone charger at the airport in Florida, you won't be able to use it when your flight lands in France. If you buy a three-pronged adapter for le portable in Paris, you might not be able to plug it in when your train drops you off in Germany. And when your flight finally bounces to a stop on the runway in London, get ready to buy a comically large adapter to tap into the grid there. But that's cool! You can take the same adapter to Singapore with you! And parts of Nigeria! Oh yeah, and if said charger doesn't support 240v power natively, make sure you buy a converter, or else it might explode.

And aside from a few oases, like the fledgling standardization of the Type C Europlug in the European Union, this is the picture all across the world.

I'd hesitate to refer to power sockets as a part of a country's culture, because they're plugs—they don't really mean anything. But in the sense that they're probably not going to change until they're forcefully replaced with something wildly new, it's kind of what they are.

What's Out There

Click for larger

There are around 12 major plug types in use today, each of which goes by whatever name their adoptive countries choose. For our purposes, we're going to stick with U.S. Department of Commerce International Trade Administration names (PDF), which are neat and alphabetical: America uses A and B plugs! Turkey uses type C! Etc. Thing is, these names are arbitrary: the letters are just assigned to make talking about these plugs less confusing—they don't actually mandate anything. They're not standards, in any meaningful sense of the word.

And even worse, these sockets are divided into two main groups: the 110-120v fellas, like the the ones we use in North America, and the 220-240v plugs, like most of the rest of the world uses. It's not that the plugs and sockets themselves are somehow tied to one voltage or another, but the devices and power grids they're attached to probably are.

How This Happened

The history of the voltage split is a pretty short story, and one you've probably heard bits and pieces of before. Edison's early experiments with direct current (DC) power in the late 1800s netted the first useful mainstream applications for electricity, but suffered from a tendency to lose voltage over long distances. Nonetheless, when Nikola Tesla invented a means of long-distance transmission with alternating current (AC) power, he was doing so in direct competition with Edison's technology, which happened to be 110v. He stuck with that. By the time people started to realize that 240v power might not be such a bad idea for the US, it was the 1950s, and switching was out of the question.

Words were exchanged, elephants were electrocuted, and eventually, the debate was settled: AC power was the only option, and national standardization started in earnest. Westinghouse Electric, the first company to buy Tesla's patents for power transmission, settled on an easy standard: 60Hz, and 110v. In Europe—Germany, specifically—a company called BEW exercised their monopoly to push things a little further. They settled somewhat arbitrarily on a 50Hz frequency, but more importantly jacked voltages up to 240, because, you know, MORE POWER. And so, the 240 standard slowly spread to the rest of the continent. All this happened before the turn of the century, by the way. It's an old beef.

For decades after the first standards, newfangled el-ec-trick-al dee-vices had to be patched directly into your house's wiring, which today sounds like a terrifying prospect. Then, too, it was: Harvey Hubbell's "Separable Attachment Plug"—which essentially allowed for non-bulb devices to be plugged into a light socket for power—was designed with a simple intention:

My invention has for its object to...do away with the possibility of arcing or sparking in making connection, so that electrical power in buildings may be utilized by persons having no electrical knowledge or skill.

Thanks, Harvey! He later adapted the original design to include a two-pronged flat-blade plug, which itself was refined into a three-pronged plug—the third prong is for grounding—by a guy named Philip Labre in 1928. This design saw a few changes over the years too, but it's pretty much the type Americans use now.

Here's the thing: Stories like that of Harvey Hubbell's plug were unfolding all over the world, each with their own twist on the concept. This was before electronics were globalized, and before country-to-country plug compatibility really mattered. The voltage debate had been pared down to two(ish) which made life a bit easier for power companies to set up shop across the world. [Note: There are technically more than two voltages in use, which reader Michael clarifies rather wonderfully here]. But once they were set up, who cared what style plug their customers used? What were you gonna do, lug your new vacuum cleaner across the ocean on a boat? Early efforts to standardize the plug by organizations like the International Electrotechnical Commission (IEC) had trouble taking hold—who were they to tell a country which plug to adopt?—and what little progress they did make was shattered by the Second World War.

Take the British plug. Today, it's a huge, three-pronged beast with a fuse built right into it—one of the weirder plugs in the world, to anyone who's had a chance to use one. But it isn't Britain's first plug, or even their first proprietary plug. In the early 1900s the Isles' cords were capped with the British Standard 546, or Type D hardware, which actually include six subversions of its own, all of which were physically incompatible with one another. This worked out fine until the Second World War, when they got the shit bombed out of them by Germany, and had to rebuild entire swaths of the country in the midst of a severe shortage of basic building supplies— copper, in particular. This made rewiring stuff an expensive proposition, so the government was all, "we need a new plug, stat!"

Here was the pitch: Instead of wiring each socket to a fuseboard somewhere in the house, which would take quite a bit of wire, why not just daisy-chain them together on one wire, and put the fuses in each plug? Hey presto, copper shortage, solved. This was called the British Standard 1363, and you can still find them dangling from wires today. Notice how even in the 1940s and '50s—practically yesterday!—the UK was devising a new type of plug without any regard for the rest of the world.

Now imagine every other developed country in the world doing the same thing, with a totally different set of historical circumstances. That's how we ended up here, blowing fuses in our Paris hotel rooms because our travel adapters' voltage warning were inexplicably written in Cyrillic. Oh, and it gets worse.

You know how the British had control over India for, like, ninety years? Well, along with exporting cricket and inflicting unquantifiable cultural damage, they showed the subcontinent how to plug stuff in, the British way! Problem is, they left in 1947. The BS 1363 plug—the new one—wasn't introduced until 1946, and didn't see widespread adoption until a few years later. So India still uses the old British plug, as does Sri Lanka, Nepal and Namibia. Basically, the best way to guess who's got which socket is to brush up on your WW1/WW2 history, and to have a deep passion for postcolonial literature. No, really.

Is There Any Hope for the Future?

No. I talked to Gabriela Ehrlich, head of communications for the International Electrotechnical Commission, which is still doing its thing over in Switzerland, and the outlook isn't great. "There are standards, and there is a plug that has been designed. The problem is, really, everyone's invested in their own system. It's difficult to get away from that."

When Holland's International Questions Commission first teamed up with the IEC to form a committee to talk about this exact problem in 1934. Meetings were stalled, there was some resistance, blah blah blah, and the committee was delayed until 1940. Then a war—a World War, even!—threw a stick in the committee's spokes, (or a fork in their socket? No?), and the issue was effectively dropped until about 1950, when the IEC realized that there were "limited prospects for any agreement even in this limited geographical region (Europe)." It'd be expensive to tear out everyone's sockets, and the need didn't feel that urgent, I guess.

Plus, the IEC can't force anyone to do anything—they're sort of like the UN General Assembly for electronics standards, which means they can issue them, but nobody has to follow them, no matter how good they are. As time passed, populations grew, and hundred of millions of sockets were installed all over the world. The prospect of switching hardware looked more and more ridiculous. Who would pay for it? Why would a country want to change? Wouldn't the interim, with mixed plug standards in the same country, be dangerous?

But the IEC didn't quite abandon hope, quietly pushing for a standard plug for decades after. And they even came up with some! In the late 80s, they came up with the IEC 60906 plug, a little, round-pronged number for 240v countries. Then they codified a flat-pronged plug for 110-120v countries, which happened to be perfectly compatible with the one we already use in the US. As of today, Brazil is the only country that plans to has adopt[ed] the IEC 60906, so, uh, there's that.

I asked Gabriela if there was any hope, any hope at all, for a future where plugs could just get along:

Maybe in the future you'll have induction charging; you have a device planted into your wall, and you have a [wireless] charging mechanism.

Last time I saw a wireless power prototype was at the Intel Developer Forum in 2008, and it looked like a science fair project: It consisted of two giant coils, just inches apart, which transmitted enough electricity to light a 40w light bulb. So yeah, we'll get this power plug problem all sorted by oh, let's say, 2050?

She took care to emphasize that the standards are still there for people to adopt, so countries could jump onboard, but even in a best-case scenario, for as long as we use wires we'll have at least two standards to deal with—a 110-120v flat plug and the 240-250v round plug. For now, the Commission is taking a more practical approach to dealing with the problem, issuing specs for things like laptop power bricks, which can handle both voltages and come with interchangeable lead wires, as well as as something near and dear to our hearts: "We have to move forward into plugs we can really control," Gabriela told me. She means new stuff like USB, which is turning into the de facto gadget charging standard. The most we can hope for is a future where AC outlets are invisible to us, sending power to newer, more universal plugs. My phone'll charge via USB just as well in Sub-Saharan Africa as it will in New York City; just give me the port.

In the meantime, this means that things really aren't going to change. Your Walmart shaver will still die if you plug it into a European socket with a bare adapter, Indians will still be reminded of the British Empire every time they unplug a laptop, Israel will have their own plug which works nowhere else in the world, and El Salvador, without a national standard, will continue to wrestle with 10 different kinds of plug.

In other words, sorry.

The video is a bit on the slow side, but here's the gist: The UK is filled with beautiful slim electronics, but these electronics have actually become skinnier than the required 1.8-inch-thick power plug. This new proposed design can collapse to 1cm (.4 inches) when not in use, allowing it to squeeze into the narrowest of bags and pockets will no longer putting unnecessary pressure on the prongs whenever your bag is set down the wrong way.

Now we just need those US to UK adapters to go through the same round of smart engineering. [Pocket-Lint]

A compact HDMI plug, called Type C, already exists, but this version is less than half the size of even that. It may seem like halving an already small plug standard isn't hugely significant, but given HDMI's apparent trajectory toward use in mobile phones and portable devices, hitting that comfortable Micro USB size might be just enough to convince hardware designers that adding an extra A/V port—dedicated, mind you—to their devices isn't such a terrible prospect. [Tech-On]

USB Type A Universal Serial Bus, the gold standard. The whole idea behind it is that this one interface will connect everything (except the stuff it doesn't), killing off the old guard, like parallel and serial ports. It moves data, and in the case of USB 2.0—which is pretty much the standard now—it does it faster, and with some extra specs for power. Clarification: USB 2.0 adds in the Battery Charging specification 1.0, which allows for dedicated charging and other power goodness. This particular connector is the type A variety. It plugs everything from your iPod to your digital camera into a computer, or whatever else. If you haven't seen this before, what are you reading this on?

USB Type B The USB Type B plug is basically a USB connector for peripherals—you've probably seen it jacked into a printer or scanner.

Mini USB It's a type of USB connector for smaller devices like cameras and phones—it takes up less real estate than a port for a Type A connection, obviously.

Micro USB Even smaller than the above Mini USB. Since it's, like, even smaller, we're starting to see it adopted by LG, Motorola and others—hopefully this is the last time they all switch power adapters on us, till wireless power makes adapters unnecessary. Update: Better pic via Mobile Burn.

IEEE 1394 (aka FireWire) An alternative to USB, Apple popularized the IEEE 1394 interface as FireWire (Sony called it i.LINK). You're probably most familiar with it on a digital camcorder (or an old school iPod), since it's really speedy for data transfers. You're looking at the four- and six-pin versions of FireWire 400. The six-pin version delivers power, the four-pin version (originally favored by Sony) doesn't.

FireWire 800 A revised, faster version of FireWire introduced in 2003, it doesn't use the same connectors as the original, making it rare for non pros—and an unnecessary pain the ass.

RJ45 The kind of plug you're used to seeing on the end of a Category 5, Cat5 enhanced or Cat6 (commonly known as Ethernet) cable, which is plugged into your router or computer's networking port. Cat5e is an update to Cat5 that supports faster Gigabit Ethernet. Cat6 is the next-gen standard that will handle speeds twice as fast as Cat5e, and has stricter rules about noise and crosstalk. Interestingly, the most recently approved IEEE 1394 spec (aka FireWire S800T) uses RJ45 connectors as well.

eSATA External Serial ATA is a branch off of the Serial ATA interface that connects your hard drive to your computer if it was put together in the last couple of years. As you can guess from the name, the difference is it's an external port, but it delivers the same insane data transfer speeds as the hookup to your hard drive. Faster than USB or FireWire, it's basically for external hard drives for quicker data transfers. You'll be seeing it more as more laptops include a port for it, usually one that can also be used with USB. There's even talk of bus-powered eSATA coming in the next year or two.

HDMI High-Definition Multimedia Interface is another one of those "it'll connect everything except all the stuff it doesn't" deals, but for high-definition audio and video. It basically replaces DVI (see below) plus S-Video and all that other analog crap. Laptops, desktops and even high-end cameras and other gadgets are getting HDMI. Besides fat bandwidth, another benefit is control: The Consumer Electronics Control (CEC) profile already lets machines send commands to other products over HDMI—that or something like it could be very useful in the PC space, too.

DVI The digital successor to VGA, Digital Visual Interface is a video connection you'll most likely see dealing with computers or computer monitors, at least until they're all replaced by HDMI. Older HDTVs have DVI ports too. It can have a few different pin arrangements, depending on whether it carries a digital (DVI-D) or analog (DVI-A) signal or both (DVI-I, for integrated). The analog deal on some types is to make them easy to adapt for use with a VGA monitor, but it's less and less noteworthy. There's also a dual-link version that carries more data for high-res displays. These are helpfully depicted at Wikipedia.

Mini and Micro DVI are dumb, shrunken, Apple-only versions of DVI. Why dumb? Because they're essentially proprietary formats. HDMI will make them obsolete before long.

DisplayPort is the newest video interface on the block, and its plane of existence is basically in the computer-to-monitor realm only. It's not even close to mainstream yet, but Dell is backing it, among others, so you might wanna know it. It can carry a whole lot of data, but it's got DRM built into the spec, so it's a double-edged sword. Update: Swapped pic out with a better one.

That's enough cable to strangle most of California, but by all means feel free to add in your own cable trivia down in the comments.
