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 e-waste. 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?

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.
