This is the charging clip for the Garmin Alpha TT10 collar. Simply clip it onto the side of the collar unit and plug your charging cable into the USB mini port to begin the charging process. This design minimizes the chance of debris building up and interfering with the connection, and the collar can easily be cleaned if mud becomes an issue.
Special Note - This clip is small and compact - and it's easy to forget to remove it from your collar when charging is complete. Remove and store in a secure location in preparation for the next charging sequence!
