USE MY 12V DC AMPLIFIER AT HOME
My 12V DC Amplifier


There are a huge number of completely different devices that can be described as an "amplifier". Only a subset of them operate using a 12V DC supply. Here is an example:



However, it doesn't really matter, the advice below applies for any device which requires an input voltage of 12V DC


  How can I use my 12-DC amplifier at my house?


Find out the power rating of your amplifier. There will be a label that says how many Watts it uses. Buy a 12V DC power supply of greater wattage that is designed to plug in to a 220 V AC electricity socket. 

If you can't see any mention of Watts on the device, multiple the input voltage by the input current. For example - the device in the picture above has a label with 12V and 12A on it.  12V x 12A = 144 Watts. Don't multiply input voltage by output current (or vice versa)



You will need to make sure that the plugs at each end are compatible with your 220V AC socket and with the connector on your amplifier.


  Can I plugged it directly to my socket that has a current of 220 Volts?


No, the plug for a 12V DC device should not even fit that socket.


  Should it be safe?


No, plugging a 12V DC device directly into a 220V AC socket will very likely destroy the device and cause it to catch fire.



If in doubt, I suggest you just take your amplifier to a local electrical store and ask them if they have a "power supply" or "mains adapter" that will suit your amplifier.
