Output: 12V Max 2A/2000mA, it means that it can supply with all amperage which smaller than 2A. ---such as 1.5A, 1A, 600mA, 750mA,800mA ,900mA all is available , For example If your device drawing the current only needs 1A then only 1A will be supplied. However, if you needed more than 2A then you will get 2A also.
