Oster 6832 10-Speed Blender, Black

Do older carafes fit on the base?

Is this blender good for chopping vegetables, cranberries, etc. not to be drunk as a smoothie but to remain in chopped state.

I am planning on taking this item to Brazil as a gift to my stepmom. Is the blender dual voltage?

Does it chop well? Looking for one to chop onions, carrots and even squash. Thank you.
