Made For Amazon, Battery Base for Echo (4th generation). Not compatible with previous generations of Echo or Echo Dot (1st Gen, 2nd Gen, or 3rd Gen).

Customers find the battery base easy to use, taking just two minutes to set up, and appreciate its portability and sound quality, with one customer noting it provides up to 4 hours of unplugged sound. Moreover, they consider it worth every penny and like its appearance. However, the functionality receives mixed feedback – while some say it works great with the Echo, others report it doesn’t work at all. Additionally, the battery life and echo quality also get mixed reviews, with some praising the battery life while others report it doesn’t stay charged long, and some saying the Echo doesn’t respond to voice commands.
