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.

The Amazon Echo Dot is essentially all the bits of an Amazon Echo that make it interesting, but without the speaker beneath it â and so it costs just one-third of the price. The Dot is one of three Alexa-enabled products from Amazon that puts the companyâs voice assistant front and centre.
