R6220 - using a power bank for router power

Hello there... i want to use a power bank(10000mah, 2.01amp) for powering my R6220.
i tested it.. and it runs smooth but my question is... is there any problem if i use in that way... cause router needs 12v/1.5a and um giving him 2.01amp( 5v power bank actually,idk it converts 5v to 12v or not).

what can i do, if its not good for my router.. ? do i need a 5v to 12v booster usb to dc power cable? or anything else...?

Thank you

       That's not what I'd expect, but you could get lucky.

       That's what the User Manual says, and I assume that the product label
    on the R6220 agrees.

       If its label says "5V", then I'd expect its output to be 5V (which is
    not 12V).

       The RAPBB1006 is intended for use with USB-powered devices.  How did
    you connect it to the R6220?  Some kind of USB cable?  (That might not
    be a good idea, but I don't know enough about the power circuitry in an
    R6220 to make predictions about what can go wrong.)

       For proper operation, you would probably need a 12V power supply.  If
    the R6220 ever wants to use 12V at 1.5A, then that would be 18W.  5V at
    2.1A is 10.5W.  The ratings of an RAPBB1006 suggest that it can't supply
    as much power as an R6220 can demand, even if you converted its 5V
    output to 12V.
