My folks from India are here and was planning to get them the Mibox. But before I head to Walmart I want to ask existing users of this Box that whether the adapter supports 220v or not. If it's only 110v then I would probably not buy as they will need to use a step down transformer or something in India to use it.
Edit: Thanks everyone for answering. This really helped.
The AB model (the one sold in the USA) has a universal power adapter (100-250V). Only the plug differs.
Source: I'm using it in Greece with just a plug adapter (we have 220V current here too).
