# Mobile Charger Power Consumption Calculation

### Charger Power Consumption Calculator:

Enter the capacity of your charger, operating hours and per unit rate. Then press the calculate button to get the charger power consumption, cost per day, per hour, per month and per year.

By default, we have added 10 watts charger values, you can change it.

 Hours Used Per Day: Hr Power Use (Watts): W Per Unit rate: INR Energy Per Day: kWh Cost Per Hour: INR Cost Per Day: INR Cost Per Month: INR Cost Per Year: INR

### Mobile charger power consumption:

The charger is the device used to charge your mobile phone batteries. It is the most mandatory device for day to day life for everyone. The capacity of the charger will 4 to 15 Watts depending upon the size of the phone. i.e Moto Turbo Charger has 15Watt capacity and which charges 3Ah battery in 15 minutes.

But non-turbocharger like Nokia 1100 has a capacity of 4 Watts per hour. Hence such a charger requires more than two hours to charge your mobile.

Now you want to know? How much your charger consumes power for charging your mobile and how much the charger consumes the power when the phone is not connected? Let see,

### Mobile charger Power consumption calculation:

In our case let we take a most popular mobile phone Redmi Note 7 charger has rated output voltage of 5V with the output current of 2 Amps. What the yearly consumption of the charger which operates 4 hours.

The charger wattage is 5*2= 10 Wh.

 10 Wh Charger Power Consumption Consumption Total (Wh) kWh Hourly 10 0.01 Day (4 hrs) 40 0.04 Month 1200 1.2 Yearly 14400 14.4

Look at the above table, your mobile charger power consumption per day is 0.05 kWh or units and per yearly it consumes 14.4 units.

### Does your charger consume electricity without a mobile?

Yes, it consumes power for the internal circuit. Look at the live video demonstration (in Tamil).

The 10 Watts charger takes 0.234mA current when the circuit is in On condition without connecting mobile. It consumes 230 * 0.000234A = 0.054 Wh. Hence,

 10 Wh Charger Without Phone Consumption Total (Wh) kWh Hourly 0.054 0.000054 Day 1.296 0.001296 Month 1.62 0.00162 Yearly 473.04 0.47304

By yearly you will waste the power of 473 Watts by plugin the charger.
