The unit comes with 2 plugs, the 220 v is a hard shell adapter locked in place by a sliding tab
and is shown already installed in their product photos
I'd take some pics to share, but now I wouldn't know where to upload them since photobucket wants , a $ 400 fee to link to them , but that's another story.
As for the adapters, I agree, with you. But that's their policy, not to be used with extension cords or adapters.
