Vaux is $49 accessory for the second-generation Amazon Echo Dot from a new startup called Ninety7 that essentially turns Amazon’s miniature Alexa device into a portable, battery-powered Wi-Fi speaker.

Vaux then recharges off the regular wall plug that you’d ordinarily use for your Echo Dot. Vaux also features a more powerful speaker than the Echo Dot’s own integrated one, which should help improve music playback on the device.
