What else can I help you with?
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 use 1A power pack for 500mA device?
Yes, you can use a 1A power pack for a 500mA device. The power pack will supply the necessary 500mA the device requires, with some extra capacity. Ensure that the voltage output matches the device's requirement to avoid any potential damage.
Can you use a 9V 500mA for a 9V 800mA?
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.
What type of power adapter is compatible with this device?
The device is compatible with a USB-C power adapter.
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.
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)
For a device requiring DC 6V 1000mA will a DC adapter output 9V 1000mA also work for this device?
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.
Can 5v 500mA run a 5v 1.8a device?
No, a 5V 500mA power supply cannot run a 5V 1.8A device. The device requires 1.8A of current to operate properly, while the power supply can only provide 0.5A. Attempting to use the lower-rated power supply could result in insufficient power, causing the device to malfunction or not turn on at all.
Will 9v 300mA power adapter work with a 9v 700mA device?
No, the adapter's power output has to be equal to or greater that the current draw of the device.
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.
Is 9vdc 500ma the same as 9vdc 1.5a?
No, 9VDC 500mA is not the same as 9VDC 1.5A. While both have the same voltage of 9 volts, they differ in current capacity; 500mA (0.5A) means the device can draw a maximum of 500 milliamps, while 1.5A allows for a maximum of 1,500 milliamps. Therefore, a 9VDC 1.5A power supply can provide more current than a 9VDC 500mA supply, which is important for devices that require higher power. Always match the power supply specifications with the device requirements to avoid damage.
