Hi all,

This is a high speed dual usb wall charger or wall adapter. Each USB port is dedicated 2.1A, so with parallel charging maximum output is 4.2A

As shown in the picture, the charger is charging my Galaxy Note 10.1 and Note2 in parallel. The current measurement in my Note2 shows 1800mA which is the maximum current Note2 can draw (even original charger shows 1800mA)

Note : In order to achieve maximum charging current, pls use short and good quality charging cable
