Can you use a 12V 150mA adapter on a device that requires DC 12 V at 1 A?

As long as the current output is greater than power supply it replaces it will work fine. If the replacement is rated for less current (amperes) than the original you don't want to use it.
Of course a DC supply has to be replaced with a DC power supply. AC with an AC supply. The polarity should be the same and the voltage should be the same and the pin and barrel should be the same diameter as well.

∙ 9y agoYes, just make sure that you check whether the device needs an AC or DC supply as some adapters change AC to DC internally. A 12 volt 1 amp adapter is the same as a 12 volt 1000 mA adapter. The device only requites 700 mA so there is 300 mA spare capacity left in the adapter.

∙ 14y agoNo. the device that requires 1 amp to run it will over heat the 150ma adaptor and burn it out.

begin to do the job it's designed for.
Wiki User
∙ 11y agoNo, the 1 amp (1000 mA) device draws too much current to draw from a 700 mA adapter. Any adapter larger that 1000 mA, as long as the voltage is the same, will operate the original device.
Wiki User
∙ 11y agoYes, 1500 mA is 1.5 amps. Your adapter is more that capable of handling the 1 amp load.

∙ 9y agoThe capacity of the adapter is correct but the voltage difference is too high to use on a 9 volt device.

Can you use a 9v dc 210mA adapter on a 12v dc 150mA device?
No, if the device requires 12 VDC then no substitute adapter of a different voltage will work.
Can a 12V 2A adapter be used for a 12V 500mA device?
The adapter's voltage must match that of the device, and its current-rating must exceed that of the device. So the answer is yes.
Can you use a 12v power adapter when device requires 6v?
No, twice the voltage applied to a device that only requires 6 volts will probably destroy the device. When a manufacturer of equipment states a required voltage for a device that is the voltage that must be used.
Can I use 12V 1A adapter for a 12V 0.16A device?
I wouldn't recommend it ! If the device needs to draw more current than is available - the adapter could overheat, posing a fire risk.
Can you use 12v 1000ma instead 12v 150ma?
12v 1000mA means that the maximum output of that unit is 1000 milliamps at 12 volts. 12v 150 mA means that the maximum output of that unit is 150 milliamps at 12 volts. So if you need 150 milliamps at 12v either will do. BUT if you need over 150 milliamps at 12v then you must go for the 1000 mA unit. By the way there are 1000 milliamps in 1 amp.
What if you use a 12V 1.5mA power adapter in place of 12V 1.2 mA one?
It will take longer to charge the device
Can 12V 1A adapter be used for 12V 2A device?
no, it may damage the appliance.1Can_12V_2A_adapter_be_used_for_12V_1A_device, 2a adapter cannot be used for 12v, 1a device if the so mentioned parameters are input parameters of the device.Yes, a 12 volt 2 amp adapter has more that enough capacity to operate a 12 volt 1 amp device. In fact the adapter can operate devices up to a limit of 12 volts 2 amps. A device larger than 2 amps connected will tend to heat the adapter up and eventually cause it to fail.
Can you replace 12v 1a adaptor used on device of 12v 700ma?
No, the new adapter will not be able to safely supply enough current.
Can you use a 12v 1500ma switching adapter on a device requiring 12v 3.0A?
No, if your device require 3.0A, 1500ma adapter which is 1.5A is not enough, voltage wise is fine, your adapter adapter will get warm, then overheat, then very likely fail.
Can you use a 12v 500mA for a 12v 150mA?
Yes. If you have a device rated at 12 Volts and 150 milliamps, you can use any power supply that will deliver at least 150 milliamps at 12 Volts. The important item is to keep the 12 volts at 12 volts. Even if you had a power supply that delivered 2000 amps at 12 volts you would be OK as it will only draw the 150ma that it needs.
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.
What would happen if you used a 19V 3.16Amp power adapter on something that called for a 12V 3Amp power adapter power supply?
You would overload and damage the device and/or the adapter.
