Now Amazon Echo owners can use their music-playing/home-controlling/question-answering/pizza-ordering cylinder without plugging it in.

Mission Cables, a manufacturer of Roku, Chromecast and Fire TV accessories, has launched the Battery Base. Consumers can slip the Echo into the Base and receive an additional six hours of playtime from a lithium-ion battery. The Echo will continue to operate uninterrupted as long as it remains within Wi-Fi or Bluetooth-enabled smartphone range, Mission Cables said.

Brian Wengreen, Mission Cables founder, told TWICE the company is currently working with Amazon to get the device offiically sanctioned.

The Battery Base features a silicone interior, non-slip grip bottom, on/off button and status indicators. It takes about 90 minutes to reach a full charge.

It’s currently available for $49.99 on Amazon.

Amazon also sells its own portable versions of the Echo: the Dot and Tap.
