I have a transformer I use to charge batteries that has an output of 12V 800 mA I would like to use on a totally different device that takes a transformer rated at 12V 300 mA. If I use the heavier transformer will I damage the device designed for the smaller transformer?

Some answers say to make sure polarity is correct. This is the type of connector where the cord to the electronic device (from the transformer) terminates with a single round male plug with a hole in the center that is a female connector. How do I check the polarity?

Yes, you can use it. No, you will not cause any damage. Having a power supply that is capable of higher output is not a problem. Your device will only draw what it is supposed to.
The problem would be if you tried to use a smaller one.
To check polarity, use a voltmeter or VOM. Most times it is marked on the device. Usually center positive, outside negative.

As long as the voltage is the same and transformer is rated the same or higher for the amperage, your power and amp requirements will be fine. The last thing you need to make sure is that the connectors are compatible.

No ,you will not do any damage .
Make sure the power jack (plug) has the correct polarity.

yes, make sure the polarity is correct. That is the + and - are in the same place.
