Adapter Interchange

[HTCStuey]

I've often used the same USB to Mini USB cable for multiple devices (after all it's only a wire). For example, the one in my laptop bag came with my old mobile, but I use it for my digicam and mp3 player also, and the one in my bed room on top of a pile of CDs/DVDs came with my mp3 player, but I also use that with my mobile, etc... you get the picture!

Anyway, it's just a universal lead (or so I hope!), and whatever mobile I use it with it charges the mobile no problems, so this suggests USB ports are a fixed power supply which is universal for devices that can be charged from them.

My question is, have all devices that support charging via USB been produced with the same power requirements, allowing their AC adapters to be interchanged?

usb is 5volt

the issue could be that depending on how the device handled changing
1 device could be charged by a range of volts
so it's ac adaptor could use 10volts and still work when using with usb's 5volts
but another device would die from having 10volts

you gotta read the ac charger really if it's 5volts or close it should work with all

With my PDA I have an adapter with a USB socket in it which plugs into my car cigarette lighter socket, which then allows you to use a USB cable to charge the PDA.
I always forget to look at the voltage when I'm in the car :mad:
But it would be great if I could use the same adapter for my mobile.
