Does a charger consume power when it is not charging a phone.

Many people leave their smartphones charging all day so they can connect the phone as soon as it asks for power. But does this affect the electricity bill?

According to information from SlashGear, most phone chargers, like USB sockets, do not have a physical power button and continuously consume energy even in standby mode. According to ZDNET, in this state, the adapter can consume up to 0.5 watts. Leaving one adapter plugged in for a whole month can result in a cost of 58 kopecks at a rate of 4.32 UAH/kWh.

However, when multiple chargers of varying quality are operating simultaneously in a home, the situation can become more severe. Cheap or counterfeit power bricks can consume 20 times more energy than the original accessories from the phone manufacturer. This not only impacts finances but also the environment due to the excessive consumption of electricity, which increases carbon emissions.

Leaving chargers in the socket even when turned off can continue to consume energy and incur costs. To save both finances and the planet's resources, it is better to turn off chargers and unplug them from the socket when they are not in use.
