Should you leave the charger plugged into the outlet continuously when not in use?

Is it okay to leave the charger plugged in continuously?

Still consumes electricity even when not charging

Chargers are designed to operate based on the principle of a transformer: converting high voltage to low voltage, changing current from alternating to direct to charge the phone.

The structure of a charger consists of 2 main parts: primary and secondary. The primary is connected to the input current, the secondary is connected to the output current, so whether the output circuit is closed or not (meaning whether it is charging or not), the input circuit is always closed if it is plugged in.

Does leaving the charger plugged in without charging consume electricity? According to the above principle, even if you are not charging your phone, it still consumes electricity, although the consumption is not as much as when you are charging your phone.

According to calculations, a basic family (multi-generational) will save nearly 900,000 VND/year if the charger is unplugged from the outlet when not in use.

Easily leads to risks when continuously charging your phone

In reality, you might think that saving a little money is not as important as the convenience of plugging in the charger continuously and charging your phone whenever you need. However, plugging the charger into the electrical outlet continuously will cause the charger to age, becoming a hazard that can easily lead to explosion risks, as warned by experts.

Especially for homes with young children, they might wet the charger head or put it in their mouths, which could lead to unfortunate accidents. At this point, remember the many tragic accidents that have occurred, mainly caused by phone chargers.

Protect the environment

In addition to ensuring your own safety and benefits, consider the environmental impact of keeping the charger plugged in every day. Thousands of chargers are plugged in continuously each year, wasting millions of kWh annually. Each kWh is equivalent to a certain amount of CO2 released into the environment each year, directly affecting your surrounding living environment.

Therefore, the advice we want to give you is: Build the habit of unplugging the charger when not in use!

For greater ease and convenience, you can choose power outlets with switches to turn them off when not in use.
