    For example i own a phone at has input of 1,000mA then i plug it to a Power Bank that outputs 2,000mA. What will happen? Will battery be damaged?

    nothing, the battery will not be damaged. But if conversed situation that the phone's input bigger than power bank's outputs, either the power bank or your battery will be damaged.

    Smartphones generally have chargers at supplies between 0.9a and 1.1a
    Amperage is the measure of how FAST electricity is moving in a circuit. Voltage is the measure of how MUCH electricity is moving in a circuit.

    Currently using S4 and the charger outputs 2.0V. The charger is the one that comes with the package.

    2.0v is VERY BAD for usb charger.usb spec requires 5v. Now 2.0a is okay, and the s4 charger should be 5v,2a.

    I'm planning to buy a power bank but i don't know what exactly to get.

    There is this one saying the Output is 5V - 2,100mA (max) and the other one is 5.3V - 2,000mA (max) both of them has 10,500mAh battery but i'm confused about their output. Please help.

    Oh so 2A is gonna destroy the battery unless the charger has an official packaging/logo.. now those 2A won't hurt.

    The fact is, smartphones 'of today' have current limiting abilities so that they only 'sip' from a 'stream' of electricity - whatever the manufacturer determined is the ideal rate. Now voltage.. overvoltage chargers will do damage because that's like turning the cup into a fountain and saying 'drink' as it covers you.

    Bad analogy?

    See my response above for an explanation, but you want the 5V 2.1A charger. 5.3 is pushing is only a little, but better safe than sorry. Think of amperage as 'potential'. It won't keep pumping electricity into a device that doesn't want it, nor will it have to eat it, itself. If you have too low of wattage in any way, you run risk of burning the charger in one way or another.
