Amazon Tap

From Wikipedia

The Amazon Tap is a smaller portable version of the Echo with dual stereo speakers.

The Amazon Tap can do the same things as the Echo; however, it is battery powered so it is portable. Initially the user had to press an activation button on the front of the Tap to speak commands. However, a February 2017 software update allows the option of activating the Tap with an activation word, just like the Echo and the Dot.
