I have this charger for 1 month, so not enough time to give a final rating. But I put 5 stars because it works very well for the moment. This transformer ANKER is bigger than the original and looks very solid. The after sales service (SAV) is very attentive; it even seems strange as it is not used! Anyway, I will return to ANKER soon as the need arises and I recommend it, especially as the price is very correct. GM Mr.
