Probably not. The other way around would be fine: a device that only needs 750mA will work fine on a 2A power supply, but one that needs 2A will NOT work on only 750mA, which is less than half the current required.

What will happen if use a 12v 400ma instead of 12v 500ma?
i am not sure, BUT according to the answer in this post:Can_you_use_a_9V_600mA_adapter_on_a_9V_400ma_scanneryou need an adaptor of 9v and AT LEAST 500mA (assuming that the appliance draws 500mA)
Can you use a 12v 500mA switching adapter going to a 12v 700mA security camera?
If the camera actually uses 700 mA in order to do its job, then the 500 mA adaptor will warm up, then overheat, and eventually fail.
Can you use 5V 1A power supply on 5V 750mA?
Yes.
If an adaptor is marked with output 12v dc and 2000mA does this mean the appliance draws 2amps when in use?
Yes and No. You have three types of adaptors: constant current with variable voltage output. constant voltage with variable current output. constant voltage with constant current output. What you are talking about is the latter. This means that the adaptor was created for a specific appliance requiring 12V/2A, which it will indeed use. Heavier appliance will not draw enough current/voltage and will malfunction. Lighter appliance will draw too much current/voltage and will overload/shortcircuit.
Can you use 750mA output charger that calls for 1000mA?
Yes - it will just take a little longer to charge the device.

Can I use 12V DC output universal ACDC adaptor with equipment that uses AC adapter 12VAC 2A?
There are many electronics today that run on 12 volt DC power. The good news for anyone who is traveling is that you can use a 12 volt AC adapter 12 VAC 2A.

Can you use a 12V AC adaptor that has a 5 amper output on multiple devices that altogether draw less than half A of power and can higher value of adaptor current fry your electronics?
The amperage output on an adapter is the rating applied by the design manufacturer. Connecting a load that draws more that the design limit of the adapter will damage the adapter. As long as your connected load stays under the adapters rating there is no problem.
