    for safety pre-caution
    my modem AC ADAPTOR don't work anymore
    input: 220V-50Hz
    output: 9V-1A

    i wanna know if i could use the two other AC Adaptor
    i have at home with
    input: 100-240V-50-60Hz 0.5A max
    output: 12v- 1.5A
    And
    input: 100-240V-50\60Hz. 0.6A

    You did not specify if the original/spare adapters output DC or AC !

    Highly likely, the modem works with 5V DC internally. The defunct adapter is converted by circuitry in the modem to produce the 5VDC it needs.

    Chances are good to swap it with your spares; IF the defunct adapter was not killed by a failure in the modem.

    Maybe.

    Maybe not.

    Both adapters are effectively equivalent.

    Without more information (preferably in less threads) I can;t be more precise.

    edit: Threads merged.

    edit2: I'd give you something more than 50/50 that the other adapters would work (and if they do it may run somewhat hotter). They will almost certainly either work or damage the modem. No likely third option.
