United Nations trying to standardize wall warts

Well, yes, but I am still trying to figure out wgat connecter they agreed upon. Everything I but needs a different one it seems.

Some Chinese ones failed basic tests, Somebody actually got killed in the bathroom by a Apple charger clone recently.

I dunno, UN failed hopelessly in Siria to get a concensus, and will fail gaian. Those are high payed jobs, that UN, and they have to do something,

My opinion on standardising charging equipment is that it has to fail repeatedly as power requirements, size of stuff, and even voltages are constantly changing. Of course the more often it fails, the longer those politicians will get payed. So as long as the UN and works on it expect no lasting results for a standard.

mmm I use ink bottles and a big ink taksn on my Epson. Not been printing much lately though.

You are anti industry anti profit anti pollution., you will never bee a UN politician.

It is on planet earh.

I am for an intergalactic charger comittee, I will head it,

Not that I doubt it might have been said, but do you have a link on this? I know the EU has been working on this for quite a while, and they've achieved some success, even with Apple.

The EU accounts for something like 185 million phones a year, China for another similar amount, so they're pretty important markets, especially in terms of unit volume.

too bad for the apple people, the EU only said it had to charge from a usbport not that the phone had to have a micro usb for charging, so they still have to carry around the cable

they already do, just look at all the markings on a charger doesn't help much when people fake them and disappear

Are they trying to standardize the AC side or DC side ?

Trying to standardize the AC side is quite hopeless due to the different AC connectors in different countries. This would also affect the mechanical size of the device, assuming you should be able to plug in a device at any mains socket in a multiple output socket assembly, regardless of 0 degree, 45 degree or 90 degree pin angle. hopefully the standard will demand that the power supply electronics is contained in the direction perpendicular to the sockets, i.e. you can plug such wall warts in every socket in an extension cord.

A few mains voltages is not an issue these days, since it is quite easy to make universal 100-240 Vac supplies.

On the DC side, such standardization would be much easier with a few DC connector alternatives, but it does not solve the problem with a huge number of discarded wall warts.

still a standard voltage and standard barrel connector for the DC side would go a long to way to be able to reuse them

many chargers already changeble slide-ons for different mains connectors and most laptop chargers use the mickey mouse plug

The United Nations has nothing to do with any of those particular markings.

That's because the cell phone vendors will no longer need to supply wall warts with their devices since it will be assumed that everyone already owns such a charger.

Standards are a good thing. Every organization should have one.

ISO and ITU. The cell phone charger standard already exists: Unfortunately, they picked the Micro USB-A connector, which has some advantages, but is essentially a throw away connector. I think passing out one of these could also solve the problem: I gave a few of these to friends as Christmas presents. Of course, one of them plugged in several phones at the same time, and wondered why the 1A USB adapter shut down.

Nifty! Right now I have several independent cords plugged in for camera, GPS, and cellphone(s). That will free up some space on my USB Port Hub. ...Jim Thompson

Oh, the do. Every company, too.

It's far better than the Mini-A.

I wouldn't want to carry one of those around. Looks like a mess.

Exactly, while on the table the metal parts can touch other things on other suplies or ground.

I finally looked at the picture! Looks like it could be substituted for dungeon apparatus at Madame's house of pain! Who thinks up such stuff??

I like the mini-USB. My RAZR phone and Samsing Clip use the same charger. And the connector is fairly robust.

Perhaps 10,000 perfect insertion/removal cycles, but not what the typical consumer inflicts upon the cell phone. I've seen far too many destroyed cell phones with broken micro-USB receptacles. The problem is that the phone usually does not use the metal micro-USB receptacle metal frame for support. Instead, they only sweat soldered the mounting tabs at the rear of the connector. A little brute force and the connector just peels off the PCB. Even if the receptacle is properly attached to the PCB, it is possible to apply sufficient force to the receptacle to tear it apart internally. Some phones are designed with recessed charging receptacles, which are a big help, but are problematic due to excessive creativity in molding the mating plug. Cleaning dirt and filth out of either connector is difficult and burnishing the contacts is almost impossible. Extra points for running high current through gold plated contacts, which are allegedly only for dry loads.

To insure confusion, some devices use micro-AB, where the receptacle fits either type A or type B plugs: Note that type-A plugs have been decreed non-standard.

Horses for course, but not useful in two-of-a-kind households.

• YES!! It is all about power. Greed breeds more greed. Just look at the US "peace"keepers. And how we have been raping South America countries since (at least) FDR (remember that guy that stole our gold).

• Like i said. It is all about power.

• And what does that have to do with the price of rice in China?

Standardizing on something like a micro-USB is just the first step. Even with the proper adapter cable, try to get Apple, Motorola and a bunch of other models to actually charge just because they see +5V is a crap shoot.

Motorola won't play nicely with an Apple USB wall wart. Apple won't play nicely with Motorola. Neither will charge off a Kindle supply. It's a mater of how the wall wart and load implement the handshake for charger capacity.

Good luck getting that to work across vendors. The best attempt I've seen is a 12V power port (cigarette lighter) charger with 'Apple' and 'Everyone Else' ports.
