Charging my EV3

Turn off your hearing aid, the device will not charge if the power is turned on. Connect the USB side to the charging cube and the lightning cable side into the charging dock. Plug the cube into an outlet, then look at the charging dock for a blue light located closest to where the lightning cable connects to
the charging dock. The blue light indicates there is the power to the charging dock.

If you look into the charging dock, you will see a hollow section where the removal wire will go when the device is inserted into the charging dock. Lower the device into the charging dock with the removal wire going into the hollow section. The device will magnetically click into place and there will be a red light to indicate the unit is charging. The red light will turn green when charging is complete. It takes between 4-6 hours for the hearing aids to charge completely and a full charge should last around 20 hours.
