A:AnswerIt’s VERY simple! Between the top and bottom halves of the charger there is a small space around the entire charger. You can unwind the cable to the desired length and rewind it when done. Simple and practical. FYI: The charger is very efficient; it charges an Apple Watch in no time at all. Most chargers are only 5 watts. I believe the Anker charger is 15 watts. I consider it one of my better purchases as far as Apple Watch accessories.
