1. A charger comprising:
- a charging coil configured to magnetically couple with a corresponding charging coil of an implantable device,an indicator configured to identify the effectiveness of a charging field created between the charging coil of the charger and the corresponding charging coil of the implantable device; and
a processor configured to;
receive a signal from the implantable device at a first time;
direct the indicator to identify a first effectiveness level based on a determined effectiveness of the charging field at the first time;
receive a signal from the implantable device at a second time; and
direct the indicator to identify a second effectiveness level based on a determined effectiveness of the charging field at the second time.

Abstract
A charger that evaluates the effectiveness of the charging field generated by the charger at an implantable device. The charger includes a charging coil, a communication module, and a processor. The processor can include instructions to determine the effectiveness of the charging field based on one or several signals or communications received from the implantable device. The charger can use the determination of the effectiveness of the charging field to vary the strength of the charging field and/or to prompt the user to move the charger with respect to the implantable device.
