Why should you not keep the charger plugged in when it is not needed?

 


 

It is always better to have a charger nearby and active. So when we only have 1% battery left we plug it in, we can do it ASAP. For this reason, leaving the charger plugged into the outlet is usually an unconscious decision for many of us.

However, we have heard many times that this is bad practice. You might also have heard more than once that keeping the charger plugged in consumes a lot of power unnecessarily in the home.
But how true is this? Here we will clarify this myth about chargers and also tell you the real reason why we should stop always connecting them to the port.

Keeping the charger plugged in will lead to electricity consumption


First of all, it is necessary to talk about "backup power", even when the equipment is at rest, it still consumes a minimum of energy. Chargers, by staying connected, continue to attract a small flow of power from the outlet. That way, a phone, tablet, etc.when barely connected to the charger starts charging immediately without problems.
Given this, it has been considered that keeping chargers connected can lead to an increase in electricity consumption at the end of each month.

How much electricity does the charger consume?


Despite the above, reports from institutions such as research institutions such as Lawrence Berkeley National Laboratory in the United States confirm that a year-round connected charger consumes only 1 watt in total.
On the other hand, other equipment like a computer can consume roughly 10 watts per year - specifically when it comes to the backup power used. As we can see, chargers aren't the first thing we should try to disconnect from power in the home when we don't need it if we are to save money and energy.

Why should I keep the charger disconnected?


However, that doesn't mean it's best to leave the chargers plugged in. In fact, the more equipment that is connected, the greater the risk of problems such as short circuits and system failure leading to fires.

This was stated by the National Fire Protection Association of America. They also noted that at least half of the house fires that occur annually are related to electrical problems in the home. Some of that, any equipment constantly plugged into outlets can get worse.
Obviously, due to the lack of standby power a charger requires, it is unlikely to be the main cause of the fire. But it could be one of the contributing factors.

In short, although chargers always plugged into the port don't make us spend as much energy or money as we used to think, disconnecting them whenever possible is still the best alternative.
 All this as a way to prevent more serious accidents in our home. Of course, in order to do this more efficiently, we don't have to disconnect chargers only when we're not using them. In fact, all you have should also be disconnected when not switched on.
