Best Answer

Yes and No.

You have three types of adaptors:

constant current with variable voltage output.

constant voltage with variable current output.

constant voltage with constant current output.

What you are talking about is the latter. This means that the adaptor was created for a specific appliance requiring 12V/2A, which it will indeed use.

Heavier appliance will not draw enough current/voltage and will malfunction.

Lighter appliance will draw too much current/voltage and will overload/shortcircuit.

Q: If an adaptor is marked with output 12v dc and 2000mA does this mean the appliance draws 2amps when in use?

Can you use any 220 volt adaptor on a 110 volt appliance?

No. 220V adaptor can't control the output voltage, 110V appliance will be fry. Use instrument transformer or voltage regulator instead.


Is an American adaptor the same as a french adaptor?

No, each device has a different input and output.


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.


Can I use an adaptor that has output of 12 volts 1000 ma to replace an adaptor has 12 volt 3 amps?

No, Your original adaptor has an output of 3 amps or 3000 ma. As you can see, the one you want to use for a replacement adaptor only has 1000 ma output, one third of the current capacity that you need.


Can an ac adapter's output be AC?

Yes an AC adaptors output can be AC. In order to change the output to AC a few components inside of the adaptor has to be removed. Pretty much all that has to be removed from the adaptor are the diodes. The gaps in the circuit then have to be bridged in order for the electricity to continue to flow to the output plug. However this can cause problems with the circuit causing the capacitors to explode. I dont recommend modifying an adaptor to output AC. Just go out and buy another one.


Does the iPad 2 have an av output?

You have to purchase a separate adaptor for this. You can do av output, hdmi output and even connect it with AirPlay onto your Apple TV.


Is this the correct power adaptor I have a seagate free agent desk and I dont know where the power adapter is and apparently it needs a 12v 2a adapter so I found an old one and used it Ok or not?

If the one you found has an output rating of 12 volts and at least 2 amps (also could be shown as 2000mA) it should work. Check to see if your device needs an AC or DC voltage and whether the one you found has the right rating on the adapters output.


You have an acdc adaptor but you dont know what its for?

Check the output voltage and mA capacity on the nameplate of the adaptor. The adapter will be useful on devices at that DC voltage and up to the mA capacity of the adaptor E.g. the nameplate may read Input: AC120 volts 5 watts. Output: DC 12 volts 200 mA.


Should the input of an ac adaptor match the output of the device?

If it is an adapter then logically it should be adapting from one thing to another so no the output will not be the same as the input.

Is it ok to use an adaptor with 4.5V 100mA output which works for an Omron BP measurement machine which needs 6.0 V 500mA output?

No. Both the voltage and the current are too low.
