We have a Gigaset C610 and because we had to live on three floors, the phone always somewhere in the house and the battery went eventually empty and then you had to walk to the main station which is now we have above. With this charger, we can charge the phone in the living room at last, I am very satisfied!
Caution: It took a bit until I found out that this charger C59H Gigaset C610 adapts to, first I looked for a charger specifically for C610 but found nothing ...
