Just disconnect an create a coil of hose in loops in direction it naturally coils, as delivered, hold together with string, or old laces or whatever. Do not wrap around between hand and elbow that leads to a mess. Also note most if not all garden hose connectors work together, eg Gardens with Hoselock. **Q: Will it join 2 female 3/4 inch connectors?** A: Hello, this conector is for the transition from 19 mm (3/4") to 13 mm (1/2") hoses. Best regards GARDENA Service **Q: It's battery powered?** A: Hello, no, it´s not.
