Yes it will work to charge the device.
HOWEVER, you MAY still have the problem I alluded to right at the beginning of this thread, where the combination of the chosen cable and power supply MAY cause the device to think it is connected to a computer.
If that is the case the unit will then power down to speed up charging after a few minutes, which is obviously not when you want when travelling.
As I said, the cable or the charger needs to supply the correct conditions on the two data pins of the USB connector to tell it NOT to switch off.
I'd guess at 95% that you will be fine, but all I keep saying is make sure you have a guarantee that you can return anything you buy, in case it doesn't work as you hope.
Incidentally, I am not an Apple user, so I would be interested to know (from anyone!) what "special" flavour of USB is required to power Apple devices (as seen on silversid's dual outlet charger).
