Alexa is actually the AI voice assistant that is now built into many different products, however when referring to this question I know you're talking about the Amazon Echo range of products. At the moment all generations and all models have to be plugged in to a power supply to work as they do not have an internal battery built in. There is however a workaround that is mentioned below.
Yes! Amazon Echo Alexa Enabled Devices Do Have To Be Plugged in.
The echo dot, echo, echo plus , echo show 5, 8 & 10 all need to be plugged in, including the newest 4th generation that only comes in the dot and echo versions.
The reason for this is because, unlike say your smart phone, these devices do not have an internal battery that can be charged up to power them without needing to be plugged in to a power source.
if you do unplug your Amazon Alexa Echo device it will completely shut off and lose all functionality.
However there is a solution that can make your echo device wireless!
And that solution is a portable battery base.
Here are some of the top rated ones from Amazon..
Remember: Alexa is the AI voice assistant that is now built into a massive array of different products, the Amazon Echo range was just the first to use this technology.
