Yes, you can use a 500mA charger for a 400mA device. The device will only draw the amount of current it needs (400mA) from the charger, so there is no risk of overloading it. However, ensure that the voltage of the charger matches the device's requirements to avoid potential damage.

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 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


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 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.


Can you use a 5v 1A charger for a 5v 500mA device?

No. In general, a charger needs to be able to figure out when the battery has reached full charge, otherwise the charger can damage the battery by overcharging it. You need to use the specific charger required for the battery. And, if you are trying to power a non-battery device that requires 1A from a 5V 100mA source, you will not be able to maintain 5V, so it will not work there either.


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.

Can you use 5.8 volt charger on 5.2 volt device?

It is generally not recommended to use a charger with a higher voltage than the device's specified input. Using a 5.8V charger on a 5.2V device may potentially damage the device or reduce its lifespan due to overvoltage. It is safer to use a charger that matches the device's recommended voltage input.


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 another charger to charge ipod?

YES! you can only use an IPAD charger or other Ipod DEVICE!


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 you use a lower watt charger for a high watt?

It is not recommended to use a lower watt charger for a high watt device as it may not provide enough power for efficient charging and could potentially damage the device or charger. It is best to use a charger that matches the wattage requirements of the device to ensure safe and optimal charging.
