I had read about the characteristics of the load before I did this. 2.1Amps
is way more than enough, I dont know why they would design theirs for 3A,
unless they intend to use the same supply for other bodies not yet released,
i.e. 645D.
... or bodies that can charge batteries.
... or lenses that take a lot of oomph to run the AF.
... or larger LCDs that take more current.
... or memory cards that take more current than mine.
Lots of possibilities... my setup is only representative. Having
more is always better, and a 3A 6.5V switching power supply is negligibly
more difficult/expensive to design/build than a 1.5A 6.5V. It's still
only a 20W power converter... trivial.
