- The mobile charger draws some power when plugged in.
- Standby power consumption is very low, but not zero.
- Short circuit, fire risk due to fake charger.
- Remove charger after charging for smart power usage.
Mobile Charger: In today’s time, mobile charger has become one of the most common things in every home. Many people just remove the cable after charging the phone but leave the charger plugged in to the socket. Some people believe that it does not consume any electricity while others consider it a wastage of electricity. In such a situation the question arises that what is the truth? Does the charger keep drawing power even without connecting the mobile?
Does the charger really keep consuming power?
Actually, when the charger is connected to the socket and the switch is on, then a small amount of electricity continues to flow in it. This is called vampire power or standby power, that is, even if your phone is not being charged, the circuits inside the charger remain active and keep drawing very small amounts of electricity.
Although this power consumption is very small but is not completely zero. Older and cheaper chargers usually draw more standby power while newer and branded chargers are designed to be quite energy-efficient.
After all, how much does the electricity bill increase?
Generally speaking, a good mobile charger can consume about 0.1 to 0.5 watts of power in standby mode. This consumption is so low that its impact is not much visible in the monthly electricity bill. Suppose your charger is drawing 0.3 watts of power and it remains connected to the socket continuously for the whole month, then its total power consumption will be very nominal. Its cost can be less than a few rupees, that is, there is no big jump in the electricity bill because of just one mobile charger.
But if many chargers, TV, set-top box, microwave and other electronic equipment are always in standby mode in the house, then the small consumption of all these together can lead to a considerable expenditure of electricity in a year.
Not only bill but also security issue
Keeping the charger always connected to the socket is not only a matter of wastage of electricity but is also related to safety. Poor quality or counterfeit chargers can overheat. The risk of short circuit or sparking may also increase if power supply is provided for a long time.
This risk increases especially in summer or in houses with bad wiring. Therefore, it is considered better to remove the charger from the socket after use.
What would be the best thing to do?
If you want to save electricity and be alert about safety, then the best way is to remove the charger from the socket after the phone is charged. This will also result in small savings in electricity and the life of electronic equipment can also be improved. Small habits make a big difference in the long run and this understanding is the real identity of smart electricity use.
