Very good value for money, even though I did not know what amperage wait. Perfect to replace the charger for my phone at night, as it loads slowly it is not a problem (1A to 1.5A for this one against my old charger). It corresponds perfectly to the charger for iPhone 3GS from a friend, the same rating, same voltage, same shape. It therefore avoids the 3 causes of degradation of battery life (too hot, too often below 30%, too powerful loading).
Only drawback: it actually makes a whistling sound when plugged in but not charging. After connecting the phone, the sound disappears, which is not bad if you sleep next (hiss not returned even if the phone is charged to 100%).
