works perfectly (100% loading) with my brand new S5 (ie battery in good condition) The charging time is correct (to speed the load a little while both use a more powerful charger that travel charger provided with S5). As already noticed in the other comment, the positioning of phone poses no problem either. One thing to remember, this is S5 pocede USB door closed by a sealing cap, it takes to open and close after each use (it will probably end up damaging the cap, which does not seem to be very solid). Use of a contactless base avoids this somewhat boring operation, also by limiting the premature wear of the USB plug and sealing plug. This base is also very practical to answer an incoming call when the device is charging: no cable to disconnect and reconnect before and at the end Appeals ATTENTION: the product works only with hull induction or S-View case for induction which must be purchased separately! (Ie 40-60 eur price has added to the base). One can also buy this charging kit "Shell base + induction + cable" or "induction base + cover + cable + charger" etc.
