The Rexton Smart Li-ion Power Charger is a desktop charging station designed exclusively for use with Rexton Legato Li and Adore Li rechargeable RIC (receiver-in-canal) hearing aids, available as a Costco member service accessory. It provides a convenient overnight or daytime charging solution, with individual slots for both left and right hearing aids and LED indicator lights to show charging status.

Compatible with the Rexton Legato Li and Adore Li product lines, this charger connects via a USB cable for flexible power source options. The Legato and Adore Li hearing aids use built-in lithium-ion batteries that do not require disposable batteries, making this charger an essential accessory for owners of those models. The charger is also sold under the Connexx brand, which is the shared fitting and accessories platform for Rexton, Signia, and related hearing aid brands under WS Audiology.
