Is it just me or is that actually bigger than the US one?

The UK one is also pretty incredible:

I like how the UK one directs the cord in a direction that avoids unnecessary bending (compared to the europlug-one)

It's small in volume but including the rigid piece of the usb connector, it can become quite a lever when the cord is pulled up or down. I wonder whether that causes mechanical problems. Edit: For comparison, the slightly larger iPad power supply supports itself against up/down motion by resting on the outside of the plug.
