Questions about this item

How do I connect the 5.5 x 2.1mm female end to my camera power cable?

Push the camera's 5.5 x 2.1mm male plug firmly into the adapter's female jack until it seats fully; the step often missed is checking that the centre pin makes solid contact before tightening any locking collar.

Will the metal tip on the 4.0 x 1.7mm male connector wear out and need replacing?

The metal tip is rated for repeated mating cycles; under normal indoor use it lasts years, but if the spring tension loosens or the plating corrodes, replace the adapter to avoid intermittent power.
