A:AnswerWe have a four bedroom house and have the main base in the kitchen and one of the units is in the garage. We've walked outside and all around the yard with the handset without losing the signal. I don't know how many feet you need, but this is about 200-250 feet away.
A:AnswerYes, each unit plugs into the wall to charge and comes with all cords and each unit has it's own base and the main base unit has the answering machine in it.
