Question [Q] Can the charger hold the load of my two android phones except for an Ipad?

I don't know if I put my question in the right place.
This is a charger I just ordered by chance with a promotion code :

My main purpose to choose this one is because most usb chargers usually cannot be the ideal power source of Apple products such as iPhone and iPad, let alone using different at the same time. At least so far this charger did not brought me any issue.

This one says it can support Apple.I believe. But my current worries about it is that : how can I control the power juice it load ? If I have plugged an iPad into this charger, can another two android phone like Samsung & HTC be added ?

I once thought I can estimate by the total marked value of Max A& V . I know it's a big question I believe someone here will offer a more sensible answer.
