A:AnswerDoes this adapter include the actual input extension pieces shown?
Yes, the adapter came with the extension pieces.
Will it charge a Lenovo Ideapad 110-17ikb? Input needed: 20v 2.25A
It is a 2.1 amp ac power adapter with a voltage range of 3 to 12v. I bought if for a 12v need and it is working great. I used it a few times for a piece of equipment that requires 18v to charge. The equipment would function but it would not charge with the low voltage amp on it. While I am not much of a tech guy, I would lean toward saying no, I don't think this particular item would fit your needs.
Hope this helps.
