For -: charging time for the Galaxy S4, starting about 40% battery remaining and to reach 100%, count at least 7 am ??????
By removing the housing and connecting the phone directly to the cable, it's faster, but I do not see the interest! (It stays much longer than a Samsung cable though)
Taking the single cable to connect the Galaxy S4 on the computer bin is simple, the phone is never acknowledged.
I HIGHLY recommend.
