The VAUX Speaker and Battery for the Echo Dot is on sale for $34.95 during Amazon’s big Black Friday Sale. This is the new lowest price this device has ever been. The VAUX Speaker essentially turns the Amazon Echo Dot into a portable speaker, like the Amazon Tap. With the Echo Dot on sale for $29.99, you can buy it and this accessory for less than the price of the Tap, which is also on sale for $79.99. That seems like a much better buy to me if you’re just wanting to easily move an Alexa speaker around your house and don’t need the ruggedness of the Tap.
