A device that only requires only low current would not typically ship with a high current charger.

Maybe I am wrong but I knew that the device itself takes care of its own charges, for they use LiIon batteries and they are responsible if they explode due to a wrong charger
This is concurred by the fact that I have several dozens of MicroUSB and MiniUSB devices and I can use whatever charger I want with whatever device I want, provided the cable fits the device. For instance I charge my keylock (that came with 300mA MiniUSB) with a Pioneer charger for 2A. I keep this always on, because it can provide all the current I need for tablets, cellphones etc.
Pardon me if I disagree.

The thing is, because of Apple, some companies make their devices compatible with Apple's non-standard wall warts and some (like Sony) did not. You can make a USB cable that will work as a charge cable and will allow devices like a Sony Reader to charge from an Apple wall wart.

I don't have any Apple products, for the simple reason that I don't freely choose a closed system, but I noticed the wall warts have USB slots. The cable indeed is different. Obviously.
In order for a new generation (older do not need it) device to charge, the data lines have to be less than 200ohm across. Older devices can charge even if connected to a PC (true data), or not. Some ask you to choose (charge, connect).
