Can you use a dc 9V 400mA ac adapter in place of 9V 500mA adapter?

No. The 200mA adapter will only produce 1/8th the current of the 1600mA adapter, and probably won't even power what you intend to use. If it does, the extreme undercurrent will likely damage the equipment itself. A possible solution is a universal adapter, which may allow you to set the voltage and/or current for use with the intended device.

∙ 11y agoIf the device that you are plugging into the 700 mA adapter draws 700 mA or less then it can be used. The mA capacity of the adapter is the maximum output that the adapter can safely supply to the plug in devices. If your plug in device needs 800 mA to operate or charge then you can not use the 700 mA adapter.

The mA reading on the adapter is the maximum current that can be supplied without it going into an overload condition. If you do overload the adapter it will heat up and usually the DC bridge will burn open making the adapter useless.

Can you use a 9V 600mA adapter on a 9V 400ma scanner?
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
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)
Can you use 9V 500mA adapter for 9v 700mA 6.3VA device?
yes, if the other adapter is a va
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 universal ac adaptor set at 9v 400mA for a portable radio set at 9v 800mA?
No. Your portable radio needs 800mA to operate. Your adapter can only produce 400mA. If you make the connection the adapter will rapidly heat up and probably burn out.
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 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 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.
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 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 you use a 1A adapter instead of a 500mA adapter?
A one amp adapter is the same as a 1000 mA adapter. If your device requires 500 mA to operate then there is ample capacity in the adapter to operate a 500 mA device. Be sure to match the type of voltage AC or DC from the adapter to the driven device. Both have to be the same.
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.
