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 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 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.
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.
Can you charge a 500mA battery with a 1300mA charger?
Yes, you can charge a 500mA battery with a 1300mA charger. The battery will only draw the amount of current it needs for charging, so it will not be harmed by the higher current output of the charger. However, make sure the charger voltage matches the battery's voltage requirement.
Can you use 9V 500mA adapter for 9v 700mA 6.3VA device?
yes, if the other adapter is a va
Will 9v 1100mA power adapter work with your 9v 500mA device?
Yes, a 9v 1100mA power adapter work with your 9v 500mA device. The mA number is the maximum amount of amperage that the adapter will produce without overloading itself. At 500 mA the adapter will only be working at half load.
Is it ok to use a 4.5v 800mA AC adapter for a device when the original adapter is supposed to be 4.5V 500mA - will it damage the device?
Yes. As long as the voltage is the same which it is. The 800mA is the capacity that the transformer can produce safely without going into an overload state. Your original adapter was rated at 500mA which means that what ever device was plugged into it draws less that 500mA. You might notice that the new adapter is slightly physically larger. So you are safe to use the new adapter with the higher rating.

Can you use a device that requires 500mA on a 1000mA adapter?
Yes, no problem whatsoever as long as the voltages are the same. The adapter's capacity is 1000 mA and your device only requires 500 mA. The draw from the adapter is only at 50%.
Can any 9v 500mA adapter replace any other 9v 500mA adapter?
No. There is a 50/50 chance it will work. Check the polarity on the label. Some adapters have the positive on the outside sleeve of the plug, others use the center portion. The device may be labeled, or use Google to locate the correct adapter for it. If you use a plug with the wrong polarity it might fry your device.
Can you use a 12VCD 500mA instead of a7.5V 800mA AC power adapter?
Yes you can. But it may damage your computers power supply.
Can you use a 1A adapter instead of a 500mA adapter?
Oh, dude, using a 1A adapter instead of a 500mA one is like using a sledgehammer to crack a nut. Technically, you can use it because it provides more current, but it might be overkill for the device and could potentially damage it. So, like, proceed with caution and maybe just stick to what the manufacturer recommends, you know?
Can you use a 9v dc 200mA ac adaptor in place of a 500mA?
Yes. The current rating should be the same or greater than the original. This means the adapter can supply up to 500mA; In your case it only needs to supply 200mA, so it is more than up to the job.
What does 500mA equal to?
500mA = 500 miliamper 1000mA = 1 amp so 500mA = .5 amps
