Answer Wiki. The Amazon Echo and Amazon Echo Dot are stationary devices (they need to be plugged in). The difference between them is that the Amazon Echo has a much better speaker built in, while the Dot is intended for use with an external speaker via line out/Bluetooth. The Dot is much smaller and cheaper so if you want Alexa in multiple locations, it's the best option.
Whatâs the difference between them? About the size of a hockey puck, the Echo Dot is basically a miniature version of the larger Echo. Like the Echo, it comes with Amazonâs voice assistant, Alexa. Through Alexa, Echo Dot users can ask questions, get the latest headlines, control smart home devices and more.
