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 output
- Correct polarity (some have reversible polarity)
- Exact same voltage as the device
- Greater than or equal to current rating of the device

∙ 12y agoYes. The amperage rating of the supply describes the maximum power the supply can provide. As long as the power rating of the replacement supply is equal to or greater than the original (1A > 500mA) and the voltages match (12v/12v), it'll power the device just fine.

∙ 14y agoIn most cases the 500ma rating is the max output of the adapter. As long as you don't draw over the 500ma rating it will work fine.

∙ 12y agoYes, you can use a DC 9V 500mA AC adapter in place of 9V 400mA adapter. As long as the device that you are plugging into the 500 ma adapter does not draw more that 500 ma it will work.

∙ 10y agoNo, the 12 volt adapter's output voltage is too high for a 9 volt 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 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 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 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.
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 12v 500mA adapter to tv antenna that has 12v 200mA?
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 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.

Yes
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.

Can you use 12v 1000ma instead 12v 150ma?
12v 1000mA means that the maximum output of that unit is 1000 milliamps at 12 volts. 12v 150 mA means that the maximum output of that unit is 150 milliamps at 12 volts. So if you need 150 milliamps at 12v either will do. BUT if you need over 150 milliamps at 12v then you must go for the 1000 mA unit. By the way there are 1000 milliamps in 1 amp.
