Nowadays, every home has at least a few charging devices. In fact, if we include household appliances such as smart watches, computers and vacuum cleaners, we realize that we use dozens of devices. Moreover, we can use separate adapters and chargers for each of these devices. So, does leaving a charger in the socket waste electricity?
Does leaving a charger in the socket waste electricity?
If “Does leaving a charger in the socket waste electricity?” or “Does the plugged-in charger consume electricity?” If you are wondering the answer to the question, let’s give it now. Yes, it consumes electricity. But this is not true for all devices. The amount they consume is also highly variable. Here are the details…
All of the chargers we use today have small transformers that connect electrical circuits to each other. Some advanced models even have voltage and current meters and limiters inside. Therefore, when we plug it into the socket, there is a small amount of electricity consumption in order for this system to work within itself.
But some chargers that we see especially in laptop computers consist of 2 parts. the first part of it is just an extension cord. This part is connected to a relatively large adapter, and the cable from it conducts electricity to the computer.
If the plug-in cable is not connected to the adapter, it does not consume electricity. Similarly, our extension sockets do not consume electricity if they do not have anything connected to them. Therefore, electricity consumption starts first in the adapter part.
