Comparison Of Innergie mMini AC15

Bought in Singapore: Model: ADP-15VH AB Input: 100-240V-0.6A 50-60Hz Output: 5V 3A, 2.1A Max for each USB

Bought in US: Model: ADP-15VH AA Input: 100-240~0.6A 50-60Hz Output: 5V 3A, 2.1A Max for each USB

The US version has Chinese translations of each term (AC Adapter, Model, ...). Otherwise seems the same. The "AA" and "AB" in the model name seems to refer to the type of plug.
