Universal Phone Charger Approved By UN Body
andylim writes "Plans for a universal mobile phone charger have been approved by the International Telecommunication Union (ITU), a United Nations body. The charger has a micro-USB port at the connecting end, using technology similar to what is commonly used with digital cameras. It is not compulsory for manufacturers to adopt the new chargers, but the ITU says that some have already signed up to it. 'We are planning to launch the universal charger internationally during the first half of 2010,' Aldo Liguori, spokesperson for Sony Ericsson told the BBC."
Although it is funny to watch all the iPhone users I work with scrabble about sharing one cable at work between them whilst we drown in a sea of standard USB cabling!
The problem with slashdot is that most of its users were bullied and stuffed into lockers as kids!
This folks is one of the two UN organisations (both older than the UN) who could run the WWW better than ICANN. The other being the Postal Union (UPU or IPU I think they changed their name).
So, there you go, the UN is not just the political shit. The ITU is what means that you can phone from point A to point B, they are the logical choice for control over the WWW and domain name system.
My last two digital cameras had mini-usb ports, neither was physically the same.
My last two digital cameras had mini-usb ports, neither was physically the same.
Then, by definition, they were not mini-usb ports.
Both Micro and MiniUSB jacks are standardized. If your two cameras didn't use a common connector, then there's a good chance that at least one of the two was using a proprietary jack for USB.
It's good to have a standard, pity it's 10 years late. Also, why the hell is this not mandatory?
Now all we need is a universal standard of (in the words of Douglas Adams) 'little dongly things' for everything else:
http://www.douglasadams.com/dna/980707-03-a.html
'The little dongly things I am concerned with (and they are by no means the only species of little dongly things with which the micro-electronics world is infested) are the external power adaptors which laptops and palmtops and external drives and cassette recorders and telephone answering machines and powered speakers and other incredibly necessary gizmos need to step down the mains AC supply from either 120 volts or 240 volts to 6 volts DC. Or 4.5 volts DC. Or 9 volts DC. Or 12 volts DC. At 500 milliamps. Or 300 milliamps. Or 1200 milliamps. They have positive tips and negative sleeves on their plugs, unless they are the type that has negative tips and positive sleeves. By the time you multiply all these different variables together you end up with a fairly major industry which exists, so far as I can tell, to fill my cupboards with little dongly things none of which I can ever positively identify without playing gizmo pelmanism. The usual method of finding a little dongly thing that actually matches a gizmo I want to use is to go and buy another one, at a price that can physically drive the air from your body...It's hard to imagine that some of the mightiest brains on the planet, fuelled by some of the finest pizza that money can buy, haven't at some point thought 'Wouldn't it be easier if we all just standardised on one type of DC power supply?'...I strongly suspect that if you stuck a hardware engineer in a locked room for a couple of days and taunted him with the smell of pepperoni, he'd probably be able to think of a way of making whatever gizmo (maybe even the new gizmo Pro, which I've heard such good things about) it is he's designing, work to a standard DC low-power supply.'
Glad to see the UN is tackling the important stuff first.
Well I'm not sure your comment makes a lot of sense, since you can already take your UK based charger (240v, 50Hz) to America and plug it in the nearest wall socket (110v, 60Hz) with a travel adaptor and it will work just fine! This is not a new thing, nearly all PSU's produced in the last 10-15 years have been light switch mode voltage converters rather than the older transformers which were heavy and expensive to make..
That's just what the current USB standard says a port must provide.
But it doesn't stop a wall charger from providing as much as the cable can bear, which has got to be quite a bit more.
Apple have already signed an agreement and stated they will be using a standard micro-usb socket on the iPhones in the future. I believe Apple will introduce this socket in 2010.

Why this was tagged !important is beyond me. This only has plus points! It is a very important step in reducing carbon- and other needless emissions. Imagine how much this saves in copper and other materials! The price of phones and other appliances can go down a small bit because the consumer doesn't have to pay for a charger every time it buys a new one. Packages become smaller so shipping new phones costs less energy. Shops can store more phones in the same space, so the chance that the phone you want is out of stock will become smaller... I could go on and on. This is a giant leap for the environment and the consumer!

Because the UN was never given the power to mandate an electronic design. They can offer an opinion (recommendation) but that's it.
Nor should the UN make that grab for power, because once you go down that road, eventually the UN will start mandating what kind of roof you can install on your house. It's bad enough I have Congress telling me how much corn/potatoes I can or cannot grow in my own backyard. They were never granted that power under the Constitution, but since the mid-1930s they've exercised the power. http://en.wikipedia.org/wiki/Wickard_v._Filburn
"I disapprove of what you say, but I will defend to the death your right to say it." - historian Evelyn Beatrice Hall
The plugs are annoying, but you can literally get a set for under ten bucks. It's usually not that hard to plan ahead and carry the one or two you will need for the countries you're visiting. Practically all phone chargers run on 100-240V, anywhere fom 50-60 Hz (and probably then some!) and all you need is the plug.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
What was wrong with the already approaching-de-facto standard of mini usb? Or is it only that popular where I am?
Mini USB is one of those things that *everyone* has a lead for, they come with cameras and mp3 players and the like. What's better about micro usb?
Universal standard?
Somebody please tell the UN that their jurisdiction is limited to this planet only, and they can't go round telling G'ould, Klimgons, Kzinti, Minbari, Mersians and Moties what to do.
My HTC charger comes with several separate pin configurations in the box. I just attach the correct one to the charger and off I go. Welcome to the 21st century. I don't need a different charger and I don't need to buy a travel adaptor.
By using micro USB, they did paint themselves in a corner for the 5 volts. However, the current provided has to be a minimum of 500mA according to the USB specs.
Having a power adapter able to supply more than 500mA won't blow up anything since the device should also work within spec and work with a minimum of 500mA.
Chargers being able to supply 5 volts at 2A won't blow up anything and recharge devices four times faster, if required/supported by the device. If not, the device will only take 500mA and the charger just won't be working at its full capacity of 2A.
I wonder if the new phone charger standard mentions a "from 500mA up to X amps" specification or not.

Not all phones will recharge this way without extra work. A co-worker and I just had a look at his new Blackberry, which refused to charge from his laptop unless proprietary software was also installed, and it refused to work with a discharged battery until at least 10 minutes after he first reconnected power and it had recharged the battery somewhat. Every other phone or portable device I've worked with worked _immediately_ after providing external power.
Standards are helpful, and I'd love to see a drop in the number of stupid adapters on the shelves of hardware stores and Staples, but amazingly stupid behavior like that Blackberry's can still be layered on top of good standards.
I'd have rather that they licensed the dock connector. It's a nice design and can carry power, FireWire, USB, audio and video signals. Going to USB seems like a step backwards.

I'd be happy if they simply killed off the wall wart.
Surely they mean terrestrial, not universal. Or are we really hoping that the Xymoleians from Sirius B will adapt to this standard?
(just don't buy them at the airport where they'll probably charge you 20€ for a crappy universal travel adapter).
Don't worry. Someone will find the way to make a terrorist threat out of socket adapters and they'll be forbidden to travel with unless bought sealed at the airport.
The wall-wart contains the circuitry that converts 110vac/240vac to low voltage DC. Killing the wall wart means that same circuitry goes into the device, meaning that devices will now be larger by the size of the wall wart.
More sensible would be to simply make everything charge via USB, as USB is already a low-power DC source, and most low power (say 10W and under) devices can be made to work from it. Future versions of USB could even be made to allow higher current delivery, allowing higher draw devices to be connected.
Devices like modem routers though will always have a wall wart, unless you want them to be obscenely large and heavy. I'm happy for those devices to stay as-is however, as the vast majority of them are 12V 1A or below, so I just bought a dozen 12V 1A adapters from eBay once, and now I don't have to worry about losing them as they all work with each others' adapters.
Just remember, as long as the voltage is the same, the adapter can work. Most devices will have their input voltage stamped on them near the power jack, match it with an adapter and off you go. Just make sure that the adapter is capable of delivering as much or more current than necessary.
E.g., a modem router than says "Input 12v 500mA" will work just fine with my standard 12v 1A adapters.
I hate printers.
What twisted your mind into thinking, a non-elected group, that is not even remotely connected to the constitutions of the countries in it, and is none of the 3 pillars of a government, would have any jurisdiction in those countries?
That would be totalitarian dictatorship. Plain and simple.
Additionally, where would you go, if that totalitarian global, all-encompassing dictatorship, would happen to not like your views and actions?? There would be not other country to flee to. The concept of asylum would cease to exist.
And you just talked about it, like it were something normal...
I fear for this world...
Any sufficiently advanced intelligence is indistinguishable from stupidity.
Even better: don't buy the travel adapter for your laptop, but after arriving just ask your host if he has a local power cord lying around (and steal that from him for your next trip :-). Alternatively go to the local electronics store (or dollar store) and buy one, they're two to five bucks.
Which would be the same if you would travel from the UK to let's say Germany or France, all with different wall outlets.
I live in Canada and over the years I've built up a small collection of European power cords. My laptops upgrade, but the power cords (mostly) stay the same.
Browsers shouldn't have a back button!! It's all about going forward...
Manufacturers don't actually need to use a wall-wart as such. They could easily use a length of cable terminated by a normal plug, with the "wart" part of it at some point on the cable away from the socket.
That way, we wouldn't have that continual problem with running out of usable power outlets because of some fucking wall-wart taking up more than its fair share of space.
Hahahahaha !
SIP a single RFC? Can you imagine the number of SIP related RFCs and associated drafts? SIP WAS simple, it is now a mess. Even if we restrict to RFC 3261, if you can asnwer the following questions you are already a MASTER in SIP:
- what is the difference between request URI and the "To" header? Are they redundant?
- what is the difference between the "Contact" header, the "P-Asserted-Identity" header and the "From" header?
- what is the loose routign mechanism and what is the relationship with the "Via" headers?
- what is the need for "from tags" and 'to tags".
If we go a bit further:
- Why is SIP/SIMPLE do we need to introduce an "etag" and why not resuing the callid ?
- etc.
We are a company that is based on SIP and very in favor of this protocol mostly form market reasons but one should not be blind: this protocol has its problems like any other. At the beginning, it was sooo "simple" that it could not even support "announced transfer" or line supervision which is a must for corporate telephony then the real people jumped in and added what it takes to make it usable and added complexity.
Even the big telco that are hated so much in this forum jumped in and created the IMS standards based on SIP (under the ETSI Umbrella = European ...). They took it to the next level of complexity but they NEEDED IT because they are the guys who enable you and me to call from A to B without even thinking about how this is done (since more that 100 years).
If you imagine one second that you can only read ONE RFC to start working on the real SIP world, you are VERY WRONG (see RFC 3581, RFC2327, RFC 3264, RFC 3550 + all the RFC dedicated to packetization, SIP/SIMPLE, MESSAGING, ....)
Now if you compare SIP with H.323, I agree that initially, one can see a lot of advantages.
- H323 has a stupid protocol layering
- slow dialog establishment, etc?
and although they have improved this, this is still not perfect but they have advandages as well:
- camera control and double video streams are a reality in H.323 world wher in SIP it is still on paper only and badly documented.
- screen and application sharing are a reality on H.323 world. They are non existant in SIP
- H.323 has defined a clean standard for NAT traversal where SIP has a set of "best practices" spread in various RFC (keepalive, rport, symetric RTP, etc.).
if you cannot read the ITU standards that is basically because:
- most of them need to be bought
- they have a strong culture of separating the function and the encoding, which renders them difficult to grasp for field hackers
- ITU protocols are often based on ASN.1 BER encoding and therefore are compact an binaries and cannot be test with a simple TELNET connection, which seems to trouble a lot of Internet gurus.

If you design a phone to be charged at 5V@2,000mA, and plug it into an adapter or USB port which can only provide 5V@500mA, your adapter (or USB port) will soon catch fire, or burn out.
The device has no way to know what current the power supply can provide, and only high-end power supplies have any form of current regulation/overload protection built-in.

Devices like modem routers though will always have a wall wart, unless you want them to be obscenely large and heavy.
I don't see any real gain from the users point of view in having that bulk and weight in an extra box.
The real reason so much stuff uses wall warts is because it makes the regulatory compliance issues much easier/cheaper to deal with.

You're lucky, not all power supplies have the same input socket.
There are three common ones afaict
the figure eight connector (2 pin 2.5A, seen on laptop PSUs and quite a bit of AV gear)
the "IEC" connector (3 pin 10A, seen on most desktop PCs, monitors, HDTVs etc)
the cloverleaf connector (3 pin 2.5A, seen on laptop PSUs)
In my experiance most stuff that has a detatchable mains lead uses one of the above three connectors
The figure eight and the IEC are very common and I'd think you'd have very little trouble borrowing a lead. Cloverleaf leads don't tend to be seen hanging around so much since they are mostly associated with newer laptops.
There is also a 16A variant of the IEC connector seen on some high end servers and workstations but not many people are likely to be traveling with those.
