RJH was thinking very hard :
That would only matter if you wanted a faster charge - is that what you're
after? If so, yes, you're right, higher current. But IME it doesn't always
work that way - some devices seem to 'choke' the input.

Each part, the charger and the thing being charged, defines its own
maximum current - it is the lower of the two figures which defines the
charge level.
