We have a Nokia 930 and a Samsung S5 which can be loaded with this device. Unfortunately, you had the cell phone positioned exactly to really get a charge. The device does not stop the S5 to load but also loads a further 30 minutes after the 100% indicator. (Then demolition on my part) Often during charging this simple interrupted because the mobile phone has become seemingly as if by magic positioned differently and now wants to be reissued. The Nokia sometimes not even invites and is then loaded ultimately wired. We now have a battery pack with the inductive charging version which suggests significantly better (hang up phone load and when fully completed) to Actually, you can not really recommend this device. Because it works, but (if one pays attention to millimeter accurate positioning you go sometime ...) 3 stars but not buy recommendation on my part!
