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 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 9V 500mA adapter for 9v 700mA 6.3VA device?
yes, if the other adapter is a va
Can you use another charger to charge ipod?
YES! you can only use an IPAD charger or other Ipod DEVICE!
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.
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
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 6 DC 100 MA charger for a device requiring 5 DC 100 MA?
Well, yes and no. If you do use it, the device may work after a fashion, but probably not correctly. Using a higher voltage charger will eventually burn your device up. How long you can use it with the overcharged charger, depends on how well the device is made and how much tolerance the engineers built into it.
Does the type of charger you use matter for having a good battery life?
Yes, the type of charger affects the battery life of your device; using a charger not recommended by your manufacturer ruins the battery life of your device.
How long does it take to charge a 1800mA with a 500mA charger?
You would usually use that terminology in hobby cars and depending where you get the battery from look at the manufacturer specifications they'll probably tell you there.
Can you use 5.8 volt charger on 5.2 volt device?
Yes.
