BleepingComputer.com: Are all Mini-USB Chargers Compatible?

This is a question regarding Mini-USB in reference to cell phones, GPS Devices, and pretty much anything with this jack.

If I have a regular wall charger (110vac) or car charger (12vdc) for one of my Mini-USB Devices, can I use that same charger for ALL devices that accept a charger in that port? I'm asking because I have a car charger for my Garmin GPS that uses Mini-USB and also have a Wall Charger for my Motorola RazrV3 Cell phone, in addition my mom's Blackjack has a Mini-USB plug. Do I need to make sure I use the right charger for the right device or is everything interchangeable?

Please note I am referring ONLY to battery charging via an outlet in either a household wall or a car cigarette lighter, I am not referring to using the protocol for linking to a computer because that's a matter of software.

As for charging your battery, the only device you'll have to worry about is the Razor. I've seen too many cases where you need an actual Motorola Razor charger vs. a standard mini-usb charger. So, if your going out of town with that V3, bring your charger!

Awesome thanks, I was hoping I could use the car cable from the GPS to charge my phone but now I gotta buy one anyway. I crunched the connector in my glovebox hinge and busted it. I guess I'm buying another head for my iGo.

Not all of them are the same. They may look the same,in size, but actually their not. I've got my motorola Razr, i saw a usb charger from my friend so i didn't bring mine. When i borrowed her's. It fitted well into my phone, but it's not charging!
