The wired doorbell gets its power from the old doorbell wires as long as it is within the voltage range stated (I think it was 12 or 15v up to maybe 40v). It was a wide range of voltage that it would take. It comes with a part you need to install in your chime .
Sorry, there was a problem. Please try again later.There is no charger. It uses the wires from your house's doorbell. If you don't have a doorbell currently in your house, you will have to get wires with the appropriate voltage and connect them.
Sorry, there was a problem. Please try again later.This specific product is hardwired. It does not require a charger, but one permanent transformer if you don't have any in your home. If you would like to have a rechargeable one, please look at battery doorbell.
