YES!
If you have a TV antenna amplifier rated at 12 Volts and 200 milliamps, you can use any power supply that will deliver at least 200 milliamps at 12 Volts. The important item is to keep the 12 volts at 12 volts. note: 200 milliamps is 0.2 amps. Even if you had a power supply that delivered 2000 amps at 12 volts you would be OK as it will only draw the 200ma that it needs.
What else can I help you with?
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 I use 12V DC output universal ACDC adaptor with equipment that uses AC adapter 12VAC 2A?
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.

Can a 12v dc 500mA adapter be substituted for a 12v dc 200mA ac adapter?
No.If it is AC output, it will blow out the power circuits of the DC device.If it is DC output, it doesn't have enough current capacity for the load of the DC device.If you want to power a DC device with a wall wart, make sure the wart is:DC outputCorrect polarity (some have reversible polarity)Exact same voltage as the deviceGreater than or equal to current rating of the device
Can a 12V 2A adapter be used for a 12V 500mA device?
The adapter's voltage must match that of the device, and its current-rating must exceed that of the device. So the answer is yes.
What is the voltage of a uniden bearcat sportcat sc 150 charger adapter?
INPUT: AC 120V 60Hz OUTPUT: DC 12V 200mA
Can you use a 12V 500mA switching adapter on device that originally required a 12V 2A?
Not for very long. If the device actually requires 2A in order to do its job, then the adapter ... which is only designed to deliver 0.5A or less ... will get warm, then overheat, and then fail. Possibly in as little as a few seconds.
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.
What type of product would a 12v Ac Adapter be used for?
A 12v AC adapter can be use to power devices that requires 12VDC and up to 500mA. It can also be use with electrical devices that require power but do not contain internal components to derive the required voltage and power from the main power.
Can you use 12v 600ma instead of 12v 500ma?
Using a 12v 600ma source is allowing 12 volts and 600 amps of power. If the device requires a 12v 500ma source, the larger source is acceptable. Please note that it will only be drawing on 500ma of the available 600ma.
Can a 12V 800MA adapter be used in place of a 12V 500 Ma adapter?
Yes
What will happen if use a 12v 400ma instead of 12v 500ma?
i am not sure, BUT according to the answer in this post:Can_you_use_a_9V_600mA_adapter_on_a_9V_400ma_scanneryou need an adaptor of 9v and AT LEAST 500mA (assuming that the appliance draws 500mA)
Can 12v 600 mA adapter replace 12v 1200mA adapter?
No, the replacement adapter has to be of an equal or greater value but never lower.
What will happen if use a 12v 500ma instead of 12v 300ma?
Using a 12V 500mA power supply instead of a 12V 300mA power supply will likely be fine as long as the voltage matches, but the higher current capacity (500mA) means the power supply can deliver more current if needed by the device. The device will only draw the current it needs, so having a higher current capacity power supply should not cause any issues.
How many 0.25W led lamps can be connected to a 12V 500mA adapter?
The LED lamp consists of the LED and some circuitry that allows it to work at 12 volts. The wattage of your supply is volts x amps. 500 ma = 1/2 amp so you have 6 watts available. So doing the math and dividing 6 by .25 you could run 24 of the lamps. Now depending on the supply it might run hot if on continuously so you might have to drop off a few lamps.
