You do not run the risk of scalding yourself when filling with hot water
Please not another charger that will eventually end up in a box

... Like the Blumtal product, however, the Wärmi is ten degrees Celsius hotter than the other three hot-water bottles, reaching 62 degrees. If that's too much for you, you have to unplug it before the heating lamp goes out. There is no other way to regulate the temperature. Six hours after it has been fully heated up on the charger, the Wärmi gives off the least heat at 30 degrees Celsius.
