    From your description you only have only 1 choice for charging the powerbank, that is the micro usb input, all the other ports you are saying are outputs. If you are asking which output should you use for charging your phone then I would read the user manual or failing that use the ismart usb output 2.4a max. You can't use an output port to charge the powerbank!

    PS. Powerbanks do charge slowly, overnight is the best option.
