So I have another charger geucht to times faster upload my S3 can. This also has 1 or 2 times works quite well. Here, the part was always very hot. Good - a lot of power is also a lot of heat I thought. After loading several times I noticed that the battery is not at full, the charger but very hot - do not mix. Yesterday on the way had this only this charger, my S3 battery was empty. Of course there was joy as the "Load" does not even lit up the LED. Fortunately, someone with another matching charger there. The part has only annoyed. At Amazon, I have applied for return and refund - let's see how it works!
Conclusion: as some write here of total failures etc. - Stay away from the part.
