Believe it or not, the manufacturers have actually gotten together
to set a standard for chargers before the government does it for
them, that is everyone except Apple. It looks like it will be the
micro USB. It's something that needed to be done years ago.

It's only been possible with the advent of inexpensive dc-dc converters. It
used to be that if a device needed 3v or 9v for example, you had to have an ac
adapter that supplied 3v or 9v. You couldn't feed it the 5v from a usb and then
convert to the required internal voltage.
