Liberate your Amazon Echo 2 from the constraints of a power cord

Ninety7 specializes in battery docks that render smart speakers portable, so it's appropriate that the company's new product for the Amazon Echo 2 features a large, easy-to-grab handle. The Sky is a replacement sleeve for the Echo 2 that docks the speaker to an 8800mAh Li-ion battery, so you can take Alexa out in the yard or on even on the road. The company says the battery should power an Echo 2 for about 8 hours, and a column of four LEDs near the bottom of the sleeve report the battery life remaining. I'm sure that will vary depending on how many times you summon Alexa and how much you use the Echo 2 to stream music. The battery gets recharged from the Echo 2's factory AC adapter and cable.
