Product Description
If the cigarette lighter socket on a power tank or jump starter battery becomes loose, you can reattach it.

You can either use the clamping ring that holds the socket inside. This simply needs to be pushed back up while pressing the socket inward from the front. This can be done with a screwdriver.

Or you can simply glue the socket in place with a standard adhesive.
