The adapter's voltage must match that of the device, and its current-rating must exceed that of the device. So the answer is yes.
No.If it is AC output, it will blow out the power circuits of the DC device.If it is DC output, it doesn't have enough current capacity for the load of the DC device.If you want to power a DC device with a wall wart, make sure the wart is:DC outputCorrect polarity (some have reversible polarity)Exact same voltage as the deviceGreater than or equal to current rating of the device
Not for very long. If the device actually requires 2A in order to do its job, then the adapter ... which is only designed to deliver 0.5A or less ... will get warm, then overheat, and then fail. Possibly in as little as a few seconds.
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.
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)
Using a 12V 500mA power supply instead of a 12V 300mA power supply will likely be fine as long as the voltage matches, but the higher current capacity (500mA) means the power supply can deliver more current if needed by the device. The device will only draw the current it needs, so having a higher current capacity power supply should not cause any issues.

No, the new adapter will not be able to safely supply enough current.
A 12v AC adapter can be use to power devices that requires 12VDC and up to 500mA. It can also be use with electrical devices that require power but do not contain internal components to derive the required voltage and power from the main power.

Yes
You would overload and damage the device and/or the adapter.
I wouldn't recommend it ! If the device needs to draw more current than is available - the adapter could overheat, posing a fire risk.
no, it may damage the appliance.1Can_12V_2A_adapter_be_used_for_12V_1A_device, 2a adapter cannot be used for 12v, 1a device if the so mentioned parameters are input parameters of the device.Yes, a 12 volt 2 amp adapter has more that enough capacity to operate a 12 volt 1 amp device. In fact the adapter can operate devices up to a limit of 12 volts 2 amps. A device larger than 2 amps connected will tend to heat the adapter up and eventually cause it to fail.
Yes, a 12V 6A adapter is generally better than a 12V 4A adapter if you need more power for your device. The 6A adapter can supply a higher current, allowing it to support devices that require more energy or to operate multiple devices simultaneously without risk of overloading. However, if your device only needs 4A, using the 6A adapter will work fine, as devices only draw the current they need. Always ensure that the voltage matches your device's requirements.
