I use a "GGMM D3 Battery Base for Dot3 to Make Dot3 Portable" to make my Dot portable within range of a wifi connection. I take it outside to mow the lawn or do chores. Battery lasts about 6 hours.

No, Dot 3rd Gen needs to be charged for continuously using. But recently i have bought a battery dock for my dot 3rd so i'm free to use it in my courtyard or garden without cable.
