Amazon Echo is a wonderful device to free your hands and this Charging Cradle frees your Alexa Amazon Echo is known to use a unique 15V, not a universal DC/AC adapter cord. It's not so convenient to move around in the house, and there may not be a power source to the front porch or back Yard
This Charging Cradle is built in poly lithium battery, and matches snugly with the Amazon Echo, and it powers your Alexa directly, which lasts for about 3-4 hours if playing in middle volume, with the stand-by time of about 6-10 hours. If you connect the 5V Input to the cradle, it will be always ready. You can use a universal 5V USB charger to re-charge the cradle.
NOTE: Fakespot "F" grade for 50% paid ads. I am taking a chance and will return if disappointed. I will use some Command tape for temporary attachment.
