I have a Sony Mini-DV camcorder that I purchased about five years ago. Last year I purchased a Sony HD Camcorder. There is only one difference when reading the specs on each power adapter that I found. The older camcorder's power block says DC OUT - 8.4v 1.5A and the newer camcorder's power block says DC OUT - 8.4v 1.7A. Does that .2 make any difference? I would like to only use one if I possible.
