A:AnswerI do not believe there is. You can try placing the speaker to your leg in an attempt to mute or lower the sound. But there is no setting for it that I know of.
A:AnswerIt does not say. But I would think it is 10 to 15 or 20 watts. It is decent sound and louder than any cell phone. I would say it's about 5 times louder.
A:AnswerNo. Google Home Mini has neither 3.5 audio jack nor BT. It only works with Chromecast enabled devices. Buy Amazon Echo mini and it will connect with this speaker. Echo Dot has both audio jack and Bluetooth.
A:AnswerI have gotten a good 100 feet away with no walls. With walls about 25 to 30 feet. I do believe it says 30 feet. But like I said outside with nothing blocking the signal I have placed the speaker on my patio and walked over to my neighbor across the street and not only did it still pick up the signal but I could still hear it playing. [ I went about 50 to 60 feet away]
