By power pack, I'm assuming that you mean transformer or power adapter?

It's not recommended. One of three things may occur -

1) The powered device will fail due to undercurrent from the transformer.
2) The transformer will fail due to the connected device attempting to draw too much current.
3) The transformer will overheat, melting its housing and possibly starting a fire from nearby combustible materials (including the housing and wire insulation).


I would tell you that you should go to your nearest Wal-Mart, Target, Radio Shack, or another retailer that sells power adapters, and purchase one with enough power for your application. (Hint - you can always go a little over on current and be safe, though the transformer won't be as efficient.)

Yes, it will work. For example a 3 ton jack will pick up a 1 ton car. The ratings on a power supply are the maximum.

Can you use a 12v dc 1A powerpack on a device that required a 12 dc 700mA?

Yes, the device will only use whatever amps it needs.


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 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.


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 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.


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 a12v 800ma adapt be used in place of a 12v 500ma adapt?

For power supplies, if the voltage is the same, the rated amperage is equal to or greater than the requirements of the device, and the plug fits, the supply is safe to use.


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.


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.


Can you use a 9v 1500ma on 9v 500ma device?

Yes. (For any pairing of power supply and device, as long as the voltages are a match (in your case: 9v), and the output (in amps or milliamps (A or mA) of the power supply IS EQUAL TO OR GREATER THAN the current required by the device (in your case 1300mA or higher) then you will be fine. Yes it is suitable: The OUTPUT VOLTAGE (5v, 9v, 12v, etc) of a power supply MUST BE EQUIVALENT to the required voltage of the device to which it is to be connected, whereas the output CURRENT (500mA, 1A, 1500mA, 2A... etc) offered by the power supply MUST BE AT LEAST EQUAL TO OR GREATER THAN the current required by the device to which it is to be connected. (in your case, for example, as long as the power supply is rated at 9v, you could use one that has a rating of 1300mA, 1400mA, 1500mA, 1A...and so-on, without any damage to either device)


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 a 12v battery be used in a 12v device?

the answer is yes as long as the device works on dc current and not ac current if you tell me what the device is i might be able to help further
