Maybe take it with you to the backyard or even the beach? You can, with a battery-powered speaker dock (and, of course, a Wi-Fi hotspot provided by your phone). > Most of the docks I've seen start at around $50, which makes this deal especially intriguing: For a limited time, and while supplies last, the Mokcao Power+ Cordless Speaker with Battery Base for Echo Dot is just $23.99 when you apply promo code 48WK6EH4.
