Yes the power pack can supply up to 1 A, so 500 mA or 0.5 A is within that limit.

Can you use 12v 600ma instead of 12v 500ma?
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.
Can a 12v dc 500mA adapter be substituted for a 12v dc 200mA ac adapter?
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
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)
Do chargers use power when plugged in with no device attached?
No they don't
Can you use a 12v dc 500mA powerpack on a device that required a 12v dc 1A?
By power pack, I'm assuming that you mean transformer or power adapter?It's not recommended. One of three things may occur -1) The powered device will fail due to undercurrent from the transformer.2) The transformer will fail due to the connected device attempting to draw too much current.3) The transformer will overheat, melting its housing and possibly starting a fire from nearby combustible materials (including the housing and wire insulation).I would tell you that you should go to your nearest Wal-Mart, Target, Radio Shack, or another retailer that sells power adapters, and purchase one with enough power for your application. (Hint - you can always go a little over on current and be safe, though the transformer won't be as efficient.)

Can you use 9V 500mA adapter for 9v 700mA 6.3VA device?
yes, if the other adapter is a va

Is it ok to use a 4.5v 800mA AC adapter for a device when the original adapter is supposed to be 4.5V 500mA - will it damage the device?
Yes. As long as the voltage is the same which it is. The 800mA is the capacity that the transformer can produce safely without going into an overload state. Your original adapter was rated at 500mA which means that what ever device was plugged into it draws less that 500mA. You might notice that the new adapter is slightly physically larger. So you are safe to use the new adapter with the higher rating.
Can a12v 800ma adapt be used in place of a 12v 500ma adapt?
For power supplies, if the voltage is the same, the rated amperage is equal to or greater than the requirements of the device, and the plug fits, the supply is safe to use.
Can you use a 12VCD 500mA instead of a7.5V 800mA AC power adapter?
Yes you can. But it may damage your computers power supply.
Can any 9v 500mA adapter replace any other 9v 500mA adapter?
No. There is a 50/50 chance it will work. Check the polarity on the label. Some adapters have the positive on the outside sleeve of the plug, others use the center portion. The device may be labeled, or use Google to locate the correct adapter for it. If you use a plug with the wrong polarity it might fry your device.
Is it ok to use a 5v 1A AC adapter for a device when the original adapter is supposed to be 5V 500mA - will it damage the device?
Yes - what matters is the voltage - it has to be the same. The device will only draws 1A as needed - the adaptor with higher amp,i.e, 2A is fine. As long as the adaptor has amps equal to or greater than those of the device, it will be ok!
Can you use a 9v 1500ma on 9v 500ma device?
Yes. (For any pairing of power supply and device, as long as the voltages are a match (in your case: 9v), and the output (in amps or milliamps (A or mA) of the power supply IS EQUAL TO OR GREATER THAN the current required by the device (in your case 1300mA or higher) then you will be fine. Yes it is suitable: The OUTPUT VOLTAGE (5v, 9v, 12v, etc) of a power supply MUST BE EQUIVALENT to the required voltage of the device to which it is to be connected, whereas the output CURRENT (500mA, 1A, 1500mA, 2A... etc) offered by the power supply MUST BE AT LEAST EQUAL TO OR GREATER THAN the current required by the device to which it is to be connected. (in your case, for example, as long as the power supply is rated at 9v, you could use one that has a rating of 1300mA, 1400mA, 1500mA, 1A...and so-on, without any damage to either device)

Can you use a 9V 500mA for a 9V 800mA?
Using an undersized power supply is not a good idea. The device drawing 850 mA being connected to a 800 mA source will work but the adapter will get warm to hot over a period of time. This overloading of the power supply will eventually destroy the adapter.
Can you use a device that requires 500mA on a 1000mA adapter?
Yes, no problem whatsoever as long as the voltages are the same. The adapter's capacity is 1000 mA and your device only requires 500 mA. The draw from the adapter is only at 50%.
