Most probably you are using a AC (117V or 220V) to DC 6V converter adapter. If yes, then the answer is no, you cannot use a lower current rating for a device that draws more current. If you plug in a device that needs DC 6V 500 mA to an adapter that can only supply DC 6V 300mA, then the adapter could start sending higher than 6 volts current which may damage your equipment or overheat the adapter.

If you are using a higher mA rating adapter, then it's okay.

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.


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 power a 9v 700ma device with a 9v 300ma adaptor?

No. The device will try to draw 700 milliamps which will overload the 300 milliamp adapter most likely causing it to burn out and possibly catch fire.


Can you use a 300mA adaptor on a 1A device?

Yes, you can use a 300mA adapter on a 1A device, but it may not work properly or could damage the adapter. The device may draw more current than the adapter can provide, leading to insufficient power, potential overheating, or failure of the adapter. It's always best to use an adapter that meets or exceeds the device's current requirements for optimal performance and safety.


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.


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.


Can you use a 300ma power supply in place of a 400ma supply?

Yes, you can use a 300mA power supply in place of a 400mA supply, but it may not provide enough current for the device to operate properly. If the device requires 400mA and only receives 300mA, it may underperform, malfunction, or even be damaged due to insufficient power. It's important to ensure that the power supply meets or exceeds the current requirements of the device for safe and effective operation.


What power cord is required for a york fitness c201 anniversary and where can I get one?

The cord your after is a 6V-DC/500MA adaptor.On the York website, you can find out the part number for the adaptor you need.You can find more information at the posted link. However, it may be easier just to head in to a local electronics store and ask about a 6V/500MA DC Adaptor - they should be able to help you out.


Can you use 12v 600ma instead of 12v 500ma?

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.


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.


Can you use a 9V 500MA charger with a mini spy camera that suggests 8V 300MA?

No, you will burn out the camera. You can pick up the correct mini spy camera power adapters in the "Related links" section just below this box.


Can you use 500MA instead of 1Amp?

Yes, you can use a 500mA (0.5A) supply instead of a 1A supply, but it depends on the requirements of your device. If the device draws more than 500mA, it may not function properly or could be damaged due to insufficient current. Always ensure that the power supply can meet the current demands of your application for safe and effective operation.
