I have re-used SRAM's power link for years on our tandem. Once, when we were climbing some hill in Tuscany, it gave away and the drive chain rolled right off the end. Fortunately, I carry spares so it was a minor inconvenience rather getting stuck somewhere inconvenient.
I just did a search an there is an explanation here as to why one should not re-use SRAM's Power Lock connector. I can't verify the answer.
