Since I, as sure of, not always want one or the other carrying a charger in your pocket through the area also, I've just ordered 2 extra charger, one for home, one for the job and a-car, if I go out of juice and I can plug in for charging the charging cable somewhere.
Both supplied cable are working properly and me is so far nothing negative noticed. Positive pricing has to be mentioned, so full marks and my buy recommendation!
