No adapter is needed, 110 and 115 volt are interchangeable.
Some 9 V adapters rated for 1000 mA will provide 9 V at 1000 mA. If you use it on a 200mA device the voltage may go up to 10-15 V and if that device can not handle the higher voltage, it it could burn out. Better adapters will only put out 9 V exactly and have no problem. Be careful of revere polarity where the positive on one is the negative pin for the other adapter.
An adapter can be used. Make sure that the adapter that you use is of a capacity that it can produce the amperage that your appliance needs. An adapter too small will burn itself open and will be of no use to anyone. Remember; Watts = Amps x Volts.
Yes, you can run a 4.3v device with a 5v power adapter as long as the amperage of the 4.3 volt device is under the amperage capacity of the 5 volt adapter.
No, it is not recommended to substitute a 12 volt 0.5 amp AC adapter with a 7.5 volt 1 amp adapter. The voltage and amperage ratings need to match the requirements of the device you are powering. Using a lower voltage adapter may not provide enough power, and using a higher voltage adapter can potentially damage the device.
That appliance might last longer if you use an eight volt adapter rather than a nine volt adapter.
No
No, of course not. The 6v adapter only produces 6v, while the load expects 9v.
No. an AC adapter will not work for equipment that needs DC.
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.
It sounds like the same thing to me.
No, the voltage of the replacement adapter must always be IDENTICAL to the original adapter and the current of the replacement adapter must be the same or larger than the original adapter.Trying to use a 9 Volt adapter to replace a 5 Volt adapter will almost certainly completely destroy the device the moment you plug it in.You did not say whether the adapters provided AC or DC or the polarity if DC. Either way both the replacement adapter and the original adapter must be IDENTICAL in this respect.
No, the voltage from the adapter should match the voltage required by the appliance.

Yes there is

Use a universal adapter.
