How can you have 2 portable air conditioners on at the same without the power cutting out?

Every time we use both of our ac's at the same time our power goes out, one for downstairs and upstairs.


Cutting off other electronics doesn't help

Update 2:

Sorry forgot to say we live in a apartment

    An air conditioner draws a lot of power all by itself, to the point where it's generally advised not to have anything else on the same circuit. Two of those on the same circuit is guaranteed to trip the power breaker for the circuit it's on, which usually only affects a room or two. If that's what's happening, then try plugging one of them in someplace else to see if it helps.

    Since you're in an apartment, two ACs on at the same time may be overloading the master circuit for the whole apartment causing all your power to go. If this is what's happening, then there's not much you can do other than only running one unit at a time.

    Try this run one AC, until ,the first room is cold and turn it off, then run the second AC until the second room is cold enough and go back and forth.  If they are in the same room, sorry you are out of luck.

    You have to make sure each AC is on a separate circuit.  In other words use an extension cord to plug it into a different outlet until you find one that works.  

      In small apartments different circuits are often located in the kitchen, but you can more easily check this by seeing which outlets still work when the one circuit cuts out.

    The answer is simple: you're overloading your circuits. You live in an apartment so it won't be possible to rehab your wiring. You'll need to find a lower-amp AC unit and see if that helps. Or use a table fan. You can't change the circuitry, so you'll have to change the appliances.

    What's happening is that you are overloading the capacity of the electrical system in your apartment. The fuse or the circuit breaker doesn't have enough amps to allow 2 AC's to go on at the same time. It's not a simple case of swapping to a higher amp fuse or circuit breaker. You will also have to replace the wires to thicker ones, enough to carry a higher load. Since (I assume) you're renting the apartment, you're not in the position to carry that out. Someone else suggested you use a generator for one (or even both) of the ACs. That could be your only solution.

    Each of them Must be on its own circuit. 


    If that isn't possible to arrange, 

    use a portable generator to run the downstairs unit.

    They draw too much power for a single circuit.  Plug them into different circuits or have the circuit upgraded.

    You need to upgrade your power to the sockets. Call an electrician to add dedicated wiring and sockets that can handle the high current the AC units draw together. As it is right now, they overload your wiring and the circuit breakers pop.

    They would have to be on separate circuits.
