I think you mean to ask if one can use a 9v 600mA adapter to power a 9v 300mA appliance. Yes, you can do that. A 9v 600mA adapter will deliver 9v at up to 600mA.
A mA is one milli amp, or one thousandth of an amp.
300mA is 300 thousandth of an amp, 300/1000 or 0.3 amps.
600mA is 600 thousandth of an amp, 600/1000 or 0.6 amps, and is twice the current of 300mA.
no is too much amperage for the device

Yes, the 3000 mA adapter has more than enough capacity to operate a 200 mA device. There will be 2800 mA of spare capacity to operate other devices.
No, it would only damage the device if you plugged the 9v into a device requiring only 5v
According to the specifications your appliance wants to draw twice the current your adaptor would supply. The likelihood this will work is slim.
Yes. A 9 volt 600 ma adapter has enough capacity. The load only being 300 ma means that the adapter still has spare capacity of 300 ma.
Yes you can.

You can use any 9v adapter as long as the output amperage is rated higher than the amperage rating of your appliance so yes a 600ma adapter can be used to power a 500ma or 400ma appliance
No. The device will try to draw 700 milliamps which will overload the 300 milliamp adapter most likely causing it to burn out and possibly catch fire.
No, a power adapter must supply the same voltage, same polarity, and at least as much current as the load requires. Your adapter can only supply 300mA, which is less than the 700mA required by the load.Your game probably will not turn on and the power adapter may be damaged.
Yes, the adaptor allows load currents of 1200 amps or less, and 500 amps is included in that. The voltage of a supply stays constant, the current that flows is determined by what power the appliance needs to run.
Using a 12v 600ma source is allowing 12 volts and 600 amps of power. If the device requires a 12v 500ma source, the larger source is acceptable. Please note that it will only be drawing on 500ma of the available 600ma.
No, the adapter's power output has to be equal to or greater that the current draw of the device.
Yes, the adaptor can take anything from 100 to 240 v.
Yes the voltage is close enough to work. What you have to be cautious about is the milliamp output of the adapter. Make sure that the output of the adapter is higher than the device that plugs into it.
It depends on the appliance. All appliances are required to have a 'nameplate' which contains information on their power and voltage ratings.
