    Help, I am by no means an EE, so I am not sure how to solve this.

    I have 3 notebooks:

    Satellite T135D-S1327
    AC Adapter output: 19V, 3.42A

    Satellite T235D-S1345
    AC Adapter output: 19V, 2.37A

    Fujitsu S2210
    AC Adapter output: 19V, 4.22A

    I also have an iGo universal AC Adapter, 15-24V (no amps listed)
    Online it shows that it supports all 3 of my notebooks, I am guessing that it auto regulates.

    However, I am wondering, since all of them have exactly the same sized adapter plug (the iGo site actually lists the same tip for all 3) if I can exchange AC Adapters between them.

    Just from my limited electrical knowledge, I should be able to charge all of them with the 2.37A AC adapter because it is the lowest current. What I don't know is can I charge the others with the higher output (amperage) adapters. Especially the Fujitsu's because that adapter sits on my desk at home and would be quite convenient.

    The best way is the opposite of what you are thinking


    Using a higher amperage ac adapter will not overcurrent the laptop ,as it will only draw the amperage needed

    Using a lower amperage adapter could cause the adapter to overheat and possibly fail

    The amps rating is the max it allows to be drawn. Higher = better and more compatibility. The laptop determines how much current is drawn, not the adapter.
