There are many electronics today that run on 12 volt DC power. The good news for anyone who is traveling is that you can use a 12 volt AC adapter 12 VAC 2A.

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.
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).

Can you run a disc man off of an AC DC adapter that puts out more power than is needed?
Hi, IF the voltage rating is the same, the output in current (most likely in milliamps or ma) of the adapter is relatively inconsequential as long as it's at least what the Discman originally required, or a bit higher. For instance, if the Discman requires 6 volts at 250 milliamps (250 ma) and you have a 6 volt adapter that has 475 ma. available, you should be able to run your Discman off of it with very little problem. Also be sure that the different adapter has the same polarity at the plug as the original though, or it could be catastrophic. Hope this helps, Cubby
Can you play cds in a guitar amp?
Some amps such as the Fender G-Dec have a CD input on them that allows you to play your CD player through the amp. On other amps, you need an adapter to go from the CD player output to the amp's input. It will work.
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.
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 you use a 12V AC adaptor that has a 5 amper output on multiple devices that altogether draw less than half A of power and can higher value of adaptor current fry your electronics?
The amperage output on an adapter is the rating applied by the design manufacturer. Connecting a load that draws more that the design limit of the adapter will damage the adapter. As long as your connected load stays under the adapters rating there is no problem.

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.
Can a 100 mA adapter be substituted with a 200 mA adapter?
A 9V 1A adapter will supply up to 9 Watts of power and a 9V 200mA adapter delivers up to 1.8W of power. The 200mA adaptor may not be able to supply enough power to a device that has been supplied with a 1A adapter. The 1A adaptor should operate equipment that originally used a 200mA adapter. Before using a different power supply, check that the outputs are both DC or both AC. If they are both DC, it is important to check that the polarity at the connector is the same for both. If AC and DC supplies are swapped or the polarity is swapped there is a risk that the equipment will be damaged.
Is an American adaptor the same as a french adaptor?
No, each device has a different input and output.
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 a display adapter a input or output device?
A display ADAPTER is neither. The Display is an output device.
High voltage low amp adaptor I have the original power adapter for my laptop. The output rating for the ac adapter is 19v 3.42A. I have a replacement that has a 30v and 2.5A.Can i use it.?
NO!!!!! Find a charger with the same voltage!! If not, you will fry your battery. The only electrical number you can go higher on is the milliwats.
How do you test the output of a household AC electrical power adaptor?
First, always read the label on the power adaptor to find out what voltage it has been designed to supply.You can use a volt meter or a 12v light bulb to check if the power adaptor is working but don't do this unless you are certain that the output voltage really is a low as that!If you don't check the label first you could damage the volt meter or the bulb and/or give yourself a dangerous shock.Another more technical answerFirstly, using a voltmeter to check that the output voltage is as specified on the label. An unregulated power adapter will usually have an output voltage somewhat higher than the voltage specified when measured using the meter alone, but will drop to nearer the required voltage when measured under a significant load. A regulated power adapter should give a fairly constant voltage reading when tested with or without a load applied. Second, using an oscilloscope to see if there is any significant "ripple" in the output voltage, the presence of which would indicate a faulty smoothing capacitor inside the adapter.
What is an AC DC adapter?
Most electronic equipment runs on DC (direct current), while the power supplied at receptacles is AC (alternating current). Some electronic equipment contains a power supply internally that converts AC to the required DC. Other equipment requires an external adapter to convert. When looking at an adapter it is important to get one that is compatible with the requirements of the equipment. The wrong adapter can damage equipment, or overheat. An adapter should be labeled with the following information. 1. check that the adapter input voltage matches your local power (i.e. 110-125VAC in US) 2. check that the adapter output voltage matches the equipment to be powered. 3. be sure the adapter output voltage is DC if the equipment requires DC--some adapters produce AC. 4. check that the adapter can supply at least as much current as the equipment requires. If it can supply more, that is fine. This will be in amps or more typically milliamps (mA) (for example it will say "200mA") 5. check that the connector on the adapter matches the input to the equipment-can it be plugged in? 6. important--even if the connectors mate, check that the polarity is the same. Unfortunately some commonly used power plugs are found wired both ways. For example, on round power connectors, sometimes the center is positive, sometimes it is negative.
