Yes, the rating of the adapter is the maximum amount of current allowed to be drawn from it. The adapter you state has a maximum of 1000 mA or 1 amp. If the device draws 700 mA's you will have 300 mA's of spare capacity.

Will 9v 300mA power adapter work with a 9v 700mA device?
No, the adapter's power output has to be equal to or greater that the current draw of the device.
For a device requiring DC 6V 1000mA will a DC adapter output 9V 1000mA also work for this device?
A device which requires 1000mA at 9 volts in order to operate will not work from an output of 500mA. This output is only half the power requirement of the device.
Will a device requiring AC DC 9V 1000mA work with an adapter that provides 1250mA?
Yes, an adaptor with a capacity of 1250 mA's will run devices that are rated up to and including 1250 mA. Always check that the voltage from the adapter matches the device.
Will a 15DC 1000mA power supply work on a device needing 15DC 1500mA power supply?
Your question is confusing, but if you are asking whether you can use a 9V/250 mA adapter to supply a load device rated at 5 V/1000 mA, then the rule is quite straightforward. The adapter's rated output voltage must match that of the intended load, but its rated current must exceed that of the load. So in your example, you cannot use the adapter with the intended load.
How can you change the 30v1000ma power output on your acdc power adapter to a output of around 30v1ma?
Your power adapter is rated up to 30 volts at 1000ma. (1 amp.) If you have a device which only draws 1 milliamp, then it should work with this adapter, as long as the voltage is correct.
Will 9v 1000mA power adapter work with your 9v 300mA device?
Yes you can, however in an unusual situation (i.e. electrical fault in the device), the adapter will allow 5x the current the device is rated for to pass into that device. In normal operation, the device will draw what it needs, based on fans running or not, etc. Under these conditions, as long as the adapter puts out the proper Voltage, the device will operate just fine.
Can you use a 12v 1000mA on a device that requires 600mA?
yes this will work fine
For a device requiring DC 12v 1000mA will a DC adapter with output 12v 2.7A also work?
No, because the provided rating of 12volt, 2.7Amp equivalent to 2700 mA (milli amphere) is a much higher as to the adapter said 12volt, 1000 mA (Milli Amphere).
Would a device requiring dc 9V 1000mA output work with an adapter with dc 5V 3A in output?
No. Usually it's a -/+ 10% difference. So, a 9v would need at least 7.2 volts or more
For a device requiring DC 12V 2Amps will a DC adapter output 12V 1000ma also work for this device?
Assuming the plug fits, and that the polarity is correct it'll work fine. Drawing less amps than the source can deliver isn't a problem, it'd be a bit like filling a glass from a pitcher. Drawing more amps than the source can deliver is what you need to watch out for, that can cause overheating and all sorts of nasty failures.
For a device requiring DC 9V 1000mA will a DC adapter output PLUS 5V 3A also work for this device?
No. The device requires a 9V supply capable of delivering at least 1A. You're trying to supply it with a 5V supply. Go buy the right adapter. Just because there's a physical fit, it doesn't mean the part is the correct one. If the 9V supply can supply a little more than 1A (say, 1100 / 1200 mA) then that would be acceptable. If can only supply 900 mA, it may not work correctly.
Will 9v 1100mA power adapter work with your 9v 500mA device?
Yes, a 9v 1100mA power adapter work with your 9v 500mA device. The mA number is the maximum amount of amperage that the adapter will produce without overloading itself. At 500 mA the adapter will only be working at half load.
