Yes.
(For any pairing of power supply and device, as long as the voltages are a match (in your case: 9v), and the output (in amps or milliamps (A or mA) of the power supply IS EQUAL TO OR GREATER THAN the current required by the device (in your case 1300mA or higher) then you will be fine.
Yes it is suitable:
The OUTPUT VOLTAGE (5v, 9v, 12v, etc) of a power supply MUST BE EQUIVALENT to the required voltage of the device to which it is to be connected, whereas
the output CURRENT (500mA, 1A, 1500mA, 2A... etc) offered by the power supply MUST BE AT LEAST EQUAL TO OR GREATER THAN the current required by the device to which it is to be connected.
(in your case, for example, as long as the power supply is rated at 9v, you could use one that has a rating of 1300mA, 1400mA, 1500mA, 1A...and so-on, without any damage to either device)
Yes, a 2500 mA power supply has a maximum output is 2500 mA so it does have enough capacity to supply a 2000 mA device's load.
No there is not enough capacity in the 500 mA output device to operate a 1500 mA device.
yes, if the other adapter is a va
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.
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.
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)
You can use any 9v adapter as long as the output amperage is rated higher than the amperage rating of your appliance so yes a 600ma adapter can be used to power a 500ma or 400ma appliance
No. The adaptor will overheat.
Using an undersized power supply is not a good idea. The device drawing 850 mA being connected to a 800 mA source will work but the adapter will get warm to hot over a period of time. This overloading of the power supply will eventually destroy the adapter.
Yes a device will only draw the amount of current it needs if the voltage is the same it will draw the same amount of current. Since your going to a power suply with a larger max current you should be fine..just don't step up the voltage.
Yes you can, as the pedal draws only 35 mA, which is less than the maximum current the supply is capable of delivering.
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.
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
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.
