1. An external charging device for providing power to a rechargeable implantable device, the external charging device comprising:
a housing;
a single button arranged in the housing;
an indicator light illuminating the single button, the indicator light comprising at least one light emitting diode (LED);
at least one processor and a memory operably coupled to the at least one processor; and
instructions that, when executed on the at least one processor, cause the at least one processor to:
determine a primary firmware state of the external charging device during recharging of the rechargeable implantable device, wherein the primary firmware state is indicative of different operations of the external charging device and each of the different operations including a plurality of various, aggregated firmware states of various functionalities associated with that primary firmware state,
display a searching indication using the indicator light when the primary firmware state is determined to be in a searching state,
display a charging indication using the indicator light when the primary firmware state is determined to be a charging state, and
display an error indication using the indicator light when the primary firmware state is determined to be an error state.
