Property me the power adapter for my S3 bought because it has more power than the Sony Ericsson AC Power Adapter that I also possess (1A vs 850 mA). But this power supply works sometimes just do not, why is that I can not even say exactly. It sometimes happens that the phone when inserting extremely slow loads, and sometimes not even fully charge. I have the power adapter here at Amazon bought from dealers (original - at least allegedly). The Sony Ericsson AC adapter, however, works perfectly, so there is definitely a problem - if only in my or generally was once an open question. In addition, the SE sits PSU much more stable in the Micro-USB jack on the phone. Anyway, I would definitely advise in any case to another current donors!
