All robot mowers need a permanent power source (all except the Ambrogio L60 Elite & Elite S+). They normally come with a transformer to plug into a 13A mains socket and a low voltage (normally around 20v) to connect the transformer to the base station. We would recommend putting the transformer inside (i.e. in the dry) and then running the low voltage cable to the base station. Sometimes that’s not possible, so we would put the transformer in an adaptable. Remember to think about where your power will come from when choosing the site for the base station or assess the RTK signal appropriately before installing your new socket.
