The Rexton Charging Station is specially designed for several Rexton hearing aids. It features two LEDs to show the charging status (one for each hearing aid). This charger must be plugged into an outlet in order to work. Please ensure you choose the correct Rexton hearing aid model from the drop down menu to ensure the charger is compatible. These chargers are NOT universal, and the correct selection is essential. If you are unsure which model you need, feel free to send us a message and we would be happy to help! A 30-minute fast charge can charge your hearing aids for up to 7 hours! Please note, if you do not have the above mentioned hearing aids, this charger WILL NOT WORK.
