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
What else can I help you with?
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.
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 600ma instead of 12v 500ma?
Using a 12V 600mA power supply instead of a 12V 500mA one shouldn't be an issue if the device connected has a current rating under 600mA. However, it's important to ensure that the voltage matches and the device does not draw more current than the power supply can provide to prevent damage.
What will happen if use a 12v 400ma instead of 12v 500ma?
Using a 12V 400mA power supply instead of a 12V 500mA power supply may result in insufficient current to power the device properly. This could cause the device to not function correctly or potentially damage the power supply due to overloading. It is generally recommended to use a power supply that meets or exceeds the required current specifications 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.
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 is the voltage of a uniden bearcat sportcat sc 150 charger adapter?
INPUT: AC 120V 60Hz OUTPUT: DC 12V 200mA

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 power supply instead of a 12V 500mA one shouldn't be an issue if the device connected has a current rating under 600mA. However, it's important to ensure that the voltage matches and the device does not draw more current than the power supply can provide to prevent damage.
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?
Using a 12V 400mA power supply instead of a 12V 500mA power supply may result in insufficient current to power the device properly. This could cause the device to not function correctly or potentially damage the power supply due to overloading. It is generally recommended to use a power supply that meets or exceeds the required current specifications of the device.
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?
You can connect up to 4 0.25W LED lamps to a 12V 500mA adapter. Each lamp would draw about 62.5mA of current. So, 4 lamps would draw a total of 250mA which is within the capacity of the 500mA adapter.
