30 Volts 500ma means: 30volts, AC or DC not specified, at a rate of 500ma = roughly 15 watts electrical energy supplied. With out the AC or DC specified no gues on what it could be used for can be made.
12 V DC 700ma means: 12 Volt Direct Current with a supply rate of 700ma roughly 8.4 watts. This type of power supply common for things like cell phone chargers, Small battery charges for things like AA or AAA Nicad or Lithium Batteries.

Can you use 9V 500mA adapter for 9v 700mA 6.3VA device?
yes, if the other adapter is a va
Can you use a 12v 500mA switching adapter going to a 12v 700mA security camera?
If the camera actually uses 700 mA in order to do its job, then the 500 mA adaptor will warm up, then overheat, and eventually fail.
If the original power supply indicates an output 9v and 700mA and you use one that indicates an output of 9v and 2000mA will this disturb the performance of the machine a pedal effect or even ruin it?
No.
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 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.
How many volt do you need if you have 12 led 3w and 700mA?
about 2wattes
Can you replace 12v 1a adaptor used on device of 12v 700ma?
No, the new adapter will not be able to safely supply enough current.
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 a 12v dc 1A powerpack on a device that required a 12 dc 700mA?
Yes, the device will only use whatever amps it needs.
Can you buy a device that plugs into standard usb port that will allow two items plugged in at once?
Yes. Many manufacturers make USB port replicators or 'hubs'. In general you will get a small box containing a USB hub with two or more USB sockets and a cable with a USB plug to go to your PC. Note that there are some restrictions with these devices - 1) not all devices will work through them. 2) There will be a very (very) small delay 3) Ensure you buy one of the same designation as the computer - if your computer has USB-2 sockets then ensure the replicator is also USB-2. 4) The maximum power that can be drawn from a USB-2 port on your computer is 500mA (700mA from USB-3 ports). Thus if you want to connect multiple devices the total current required by all of them must be less than this limit - or buy a replicator which has a separate power supply then the output from all those new ports can be 500mA each (700mA if it is USB-3). To keep the area round my PC clear of cables I use a 7-way powered external hub with everything plugged into that - this works fine. If you have a vast number of devices you can 'daisy-chain' multiple hubs if you really need to - put the slower devices which process least data further down the chain to get the best performance from faster devices - eg an external USB disk-drive should be as early as possible in the chain.
Can you power a 9v 700ma device with a 9v 300ma adaptor?
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 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.
