With this charger I am not convinced 100%.
The reason is that here are some points to inconsistent:
Thus, with the device while easily Bluetooth headsets and Apple products charge in smartphones from Samsung, however, there are problems. (I know, here in the reviews are circulating some "Solder instructions", but I do not trust me not to that.) So a Samsung S Advance is to deep discharge (device has itself off) is no longer charged with the charger, no matter how long you can put it on the charger. iPhone cases are, however, charged correctly.
Also, there are problems, if one uses the Samsung as Navi: Here the charging power is so low that the Samsung is discharged during navigation and at worst you have to stop navigating to initially charge the device again.
Furthermore, the much too bright blue LED disturbs, especially with Nachfahrten you almost blinded, here helps only masking or paint.
Conclusion:
Who wants to Apple devices or headsets load simultaneously, can safely access, at Samsung, I have found problems. I can not say, well I do not know whether the problem might be to look at what it looks like Samsung with other manufacturers.
