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.
A 9v 1000ma adapter will operate a 9v 500ma device.
Yes! It will work well because your device needed only 300mA, but the adapter can afford until 500mA.
A device which requires 1000mA at 9 volts in order to operate will not work from an output of 500mA. This output is only half the power requirement of the device.
the excess 500mA will not be used, hence, it will not damage your device. Just make sure you have the proper voltages.
No, the 100mA adapter is too small. The adapter that can be used has to be at least 500mA or larger.
No there is not enough capacity in the 500 mA output device to operate a 1500 mA device.
No, the 12 volt adapter's output voltage is too high for a 9 volt device.
Yes, that will be safe.
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.
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.
yes, it will just charge the device faster..
No, the charger has to be equal to or greater than the device it is charging.
yes, if the other adapter is a va
500mA = 500 miliamper 1000mA = 1 amp so 500mA = .5 amps
Yes, the supply of 500 mA will supply a 300 mA device very nicely.
No, both the voltages do not match and the device draws more current than the adapter can supply.
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.
Yes, as long as the capacity of the adapter is larger than what the device needs to operate it will work nicely.
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.
Yes, the 400mA refers to the maximum current the device needs, the power supply can deliver 500mA so it won't have it's maximum current output exceeded.
No.5A = 5000mA500mA = 0.5A
It will be fine the device will only draw what it needs
p=i square x r = 500ma * 500ma = .25 * 4.7k = 1175 watts
