That depends on what you're going to do with it. The phone itself won't draw 
more than 1A but if the phone is charging while in host mode the charger may 
need to supply 0.5A to the USB device(s) too.

Note that as the chargers are unlikely to have the 47k resistor on the ID pin 
you will probably have to set the charge rate to 500mA or 1A as explained in 
the wiki:
