Are you talking about cables that have a micro USB connector on one end that plug into your device or a standard USB connector on the other end that goes into your PC or an AC adapter?

In the first case, I personally wouldn't hesitate to interchange those cables. A few years ago, the European Commission, and other international groups, settled on the micro USB connector as the standard connector to be used on cell phones to charge the device. This was specifically done to allow customers to use the same cable for multiple devices. The idea was to protect the environment by not having to manufacture or dispose of as many chargers for our electronic devices. Apple obviously chose not to follow this standard.

In the second case, given how little power is conveyed through the USB port, I'd still feel comfortable interchanging such cables and chargers. Probably the best thing though, is to use the charger that came with your device or do a bit more research until your comfortable.

One correction to Garth's statement below. It's best to follow the battery care practices for the type of battery being used. Tips on using NiCad batteries still apply to NiCad batteries. The change is that more and more devices use Lithium Ion batteries, and the care and feeding for LI batteries is different from the NiCad batteries that used to be so popular.

There is no issue with using the various chargers with different
devices. Given that the charger/manufacture is at least half decent.
Much of our knowledge about battery care from the older rechargeable
batteries should be thrown out when it comes to the batteries we find in
iOS devices and other equipment of the era.Some of it can actually be
deleterious to their long term use.

I have several chargers that were shipped with specific devices, all
of which have USB plugs at one end of the cord.  Could I use the same
USB charger to charge these various devices?  In the old days, an AC
adapter would have a specific plug on it to prevent it from being used
to charge a device that needed a different voltage or polarity.  I
think the answer to my question is that it is not a good idea, that I
should use the charger that came with the device, but am I being
overly paranoid?After all, all these devices say they can be charged
from my computer.
Thanks for any opinions.
