If you are using your electronic device continuously, the DC/AC adapter will generate excessive heat very quickly. If this is the situation with your adapter, it can cause overheating issues and decrease the life span of it. Not only that, it is also a fire risk. Power supply adapters that are overheating get damaged quicker. This is because the excessive built up heat trapped inside melts down the electrical transistor components. If your AC adapter is too hot to touch, it is a symptom that it is suffering from overheating.
1) Ensure the surroundings around the adapter is placed in a none cluttered environment. An cluttered environment around the adapter can promote heat to built up quickly. So ensure that your adapter is placed freely away from other adapters and wiring.
2) Choose a cool location to place the adapter in. If the room temperature is very warm, the adapter will overheat quicker. Turn down the heating inside the room and open a window to reduce room temperatures.
3) Obtain a computer fan and attach it directly onto the adapter. The computer fan will force cool air onto the power brick. This will help bring down internal temperatures and reduce possibilities of overheating issues to develop. You can run a computer fan from a 9 volt square battery or an external mobile phone adapter.
