United Nations trying to standardize wall warts

    Surfing away from news stories about the
    30MHz to 300 MHz switching power supplies
    the first time I ran across a story that
    the United Nations wants to standardize
    wall warts across many different brands
    of similar equipment to make replacement
    and recycling easier and to cut back on

    Supposedly it's been warmly received by
    cell phone makers so far.

    But weren't these wall warts already on
    the way to being standardized because
    of the option of using USB port power?

    Then I remembered that lots of these wall
    warts are inferior quality fire hazards.

    Do you think the UN will get into
    regulating the QUALITY of wall warts
    to cut down on e-waste? LOL

    Is the UN trying to become a government
    itself or a government regulator?

    Do you think they'll standardize computer
    printer ink jet and laser toner refills?

    I'd actually like to see them end the
    refill scams with "chipped" cartridges
    and support refilling.
    That would also cut down e-waste.

    But why the United Nations?

    Aren't there already international
    organizations to standardize things
    like that?
  2. 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

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

    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.

    "the USB-IF will no longer certify products that use the Mini-A and Mini-AB connectors nor products that use them. This change is effective immediately. "

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

    * 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?

    No, 5V is just fine. USB is the question mark. The "spec" isn't
    enough to charge something like an iPad in a reasonable amount of
    time. Even a cell phone is really pushing it at a half amp.
    It's not an "implementation of a handshake" at all. The decision
    about how to charge is made by sensing resistors on the device. If
    they're not there, the normal USB handshake goes on. Of course, USB
    limits the charge to .5A. Some *chargers* don't like the load up to
    that point.
    It's done all the time but only if this is a requirement of the
    charger. MicroChip has some interesting solutions for this.
