Hi,
I don't know about the original poster's thinking, but for me, I like the type of charger that I posted, especially when travelling, because I don't have to worry about keeping track of either a power cable for the adapter (in some cases) or a USB cable and someplace to find a USB port. It's all a single item, and assuming it is 100-210V, I just the charger itself.
I think the other aspect of what the OP was asking for was an actual Sony charger (vs. an after-market one). I usually have both types.
