Sure, a lot of stuff exists that use that old cylindrical interface, but switching to a usb plug wouldn't be a big deal. I wonder what the cost difference is between the two types of plugs.

But speaking of mini-USB cables (see my post immediately below), did you know that they have five connections, not four? The fifth is for a pull-up resistor that lets the cable charge some devices. My daughter's MP3 player was one of those. The cable that came with it would only charge the player when connected to a computer USB port but not to a charger. Pin 4 needs a pull-up resistor so the charger knows there's something connected to it. PCB USB ports don't have that.



I have a blog about this that I can post here on request.

Don't take away my cigarette lighter socket even though I have never smoked and never will. Why, because what if you need to power something besides a phone charger? For example, my GPS plugs directly into the lighter socket. Now true, the other end of the cable is a mini-USB so I could use a mini-USB cable plugged into a USB socket, if my cars had them.

Well, my "new" car is a 2001 and my "old" one is a 1999. Both have lighters.

I have one of those dual usb chargers.

I would assume that with smoking on the decline (it is isn't it?) that more manufacturers would simply put usb chargers in the place of the lighter. Hell, even if smoking isn't on the decline, energy sucking devices are obviously on the rise.

I keep two Apple cables and a micro-USB cable on the car for charging.

>many consumers were frustrated when they tried to charge their portable devices in cars.

Well, it depends on how long you're in the car, doesn't it? If you take a 15 minute drive and you start with your phone at 20%, do you expect 100% in 15 minutes? Wou wonlt get that from a home charger. For less than about $15, you can get a dual charger that plugs into a cigarette lighter. I have a dual charger. Unless you're on a 2-hour drive, don't expect your phone to be fully charged.
