Does it make any difference on output amperage if output voltage is the
same in wall plug/USB charger adapters? Referring to 1 amp vs 1.8 amps.
Former is for iPhone & latter for Kindle Fire HD. Was hoping to use one
of these adapters rather than having to buy another one for Samsung
Intensity II phone. Both have 5 volts output.

Volts o/p is a specification. Amps o/p is a maximum capability.
So if you have a wall wart rated 5 volts & 1.8 amps, it can be use for
anything that wants 5 volts and up to 1.8 amps. Your 1 amp Iphone will
run fine, just a bit cooler.

Exception: If the Kindle charger is poorly designed, it MAY need the
full 1.8 amp o/p to pull the voltage down to 5. Measure the voltage it
puts out when connected to the Iphone.
