This cable is a convenient and effective way of connecting multiple watch winders together, allowing them to run off only one power source. This reduces the need for clunky power strips and A/C adapters. Perfect for use with all WOLF winder systems.
This lithium battery is great for providing your module(s) 4.1 winder with continued power from an external source. The small pocket sized battery is extremely efficient, durable, and easy to use. In the 600 Turns Per day (single direction setting), the 21W external lithium battery can supply one 4. 1 winder with power for about 240 days, six winders 40 days or 12 winders for about 20 days. Higher turns per day and increased use of LED light up display will result in shorter battery life while lower turns per day will result in longer battery life.
