Hello & Welcome to Just Answer,
Sorry to hear of any issue with your device or charger.
You MAY be able to get one of the charging clips at a LOCAL sporting goods store - that carries these devices, OR perhaps a gold Pro-shop (probably expensive there).
But you can also get them online at places like Amazon. I have a link to one such listing below.
By the way, the Garmin Part number for this clip is: 010-11029-02
Please let me know what you find or if you have any more questions.
Thanks & Stay Out of the Hazards, Greg A.
