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.

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.
Can you safely use a universal AC adaptor set for 9V 300mA for a game that requires a 9V 700mA?
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.
Can you use 9v 100ma adaptor for powering a leap pad instead o 9v 700ma?
No, if the device needs 700mA of current, your power adapter cannot supply adequate current.
Can you use a 9v 600Ma adaptor to power a 9v 300Ma appliance?
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.
Will 6v 300mA power adaptor work with a 6v 500mA device?
Most probably you are using a AC (117V or 220V) to DC 6V converter adapter. If yes, then the answer is no, you cannot use a lower current rating for a device that draws more current. If you plug in a device that needs DC 6V 500 mA to an adapter that can only supply DC 6V 300mA, then the adapter could start sending higher than 6 volts current which may damage your equipment or overheat the adapter. If you are using a higher mA rating adapter, then it's okay. For more technical details, see: http://www.jaycar.com.au/images_uploaded/plugpack.pdf
Can you use a 9v dc 1000ma adaptor for a device that has 'power input' of 15v dc 800ma?
A: Disregarding the fact of different voltages there is the power to be concerned 9v x 1A = 9W, 15V X .8 = 12W. THE DEVICE WILL BE UNDER POWER.
Can you use a DC 9v 300MA adaptor to power a 9v 400MA device?
The voltage would match but the amount of power would likely not be enough to run the device. Under-power will not likely harm the device, but it won't work correctly. Always use the correct voltage/power for your devices!
Can you run a device that requires 700mA with a power supply that generates 1.8A?
A power supply that produces 1.8 amps is the same as saying 1800 mA. What has to be taken into account here is if the voltages are the same. If the device that uses 700 mA has a specific voltage to operate on can the power supply provide the same voltage. Another factor to look at is , both the device and the power supply have to match their AC or DC requirements. One can not be AC and the other DC or vice versa.
What charger is required for a power craft 20 million candle power rechargeable halogen spotlight?
2-volt batterys I need the charger for this 20 million CP light
Can you plug a 100-240volts power adaptor to a 110-220volts outlet?
Yes, the adaptor can take anything from 100 to 240 v.
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 9v 300mA adapter on a device that requires a 9v 400mA adapter?
No. The voltage rating is the same, but the lower current rating on the 400ma power supply might cause the voltage to drop way below 12 volts, and on some devices a lower voltage than it is rated for will cause it damage.
