+ Quality workmanship
+ Does not get warm!
That seemed all cheaper power adapters to be the problem, partly written by braised plugs and flying out fuses, and this risk I did not want to go.
+ With the supplied cable easy charging and sync with iTunes (iPhone 3G)
Extra pluses:
+ Two high-quality cables (are slightly thicker and stiffer than the Apple original, in my opinion not a disadvantage)
+ Two USB outputs on connector
The additional cost of a charger with a connection to a two-port was so low (currently 17.39 vs. 14.61), I take that as a plus point. Although I have at the moment no two devices for charging, but if you run the electronics considered nowadays that's only a matter of time.
So 100% buy recommendation.
