User interface for external power source, recharger, for an implantable medical device. At least some of patient controls and display icons of an energy transfer unit are common with at least some of the patient controls and the display icons of a patient control unit. An energy transfer unit is operable by the patient with less than three operative controls to control energy transfer from the external energy transfer unit to the implantable medical device. An external antenna having a primary coil can inductively transfer energy to a secondary coil of the implantable medical device when the external antenna is externally placed in proximity of the secondary coil. An energy transfer unit has an external telemetry coil allowing the energy transfer unit to communicate with the implantable medical device through the internal telemetry coil in order to at least partially control the therapeutic output of the implantable medical device.
