Cell phone charger electricity usage

What is electricity consumption of average/common Cell phone charger ?

Due to their ability to operate for extended periods of time on a battery, cell phones, mobile phones, and even smartphones, and tablets all have very high energy efficiency. While charging, cell phones typically require 2 to 6 watts, however, a charger left plugged in without a phone would use 0.1 to 0.5 watts. Under regular use circumstances, recharging an iPhone or Android phone will normally cost less than $1 over the course of a year.

To determine the energy usage of a cell phone charger utilizing 20 Watts for 2 hours per day at a cost of $0.10 per kWh, click calculate.

Kilowatts per dayhelp Here you will see a value for how much energy (in watts, kilowatts or megawatts) the device will consume per day if it is used for the time you specify. The formula "Hours used per day" × "Power use" is used.:

Watts Kilowatts Megawatts

Hours Used Per Day: Indicate the average number of hours per day that the device is used. If the daily power usage is less than one hour, enter the number as a decimal (for instance, 30 minutes a day equals 0.5).

Power Use (Watts): Type in the watts that represent the device's typical power use.

Price (kWh): Enter the price per kilowatt hour you pay typically; our calculators use a default value of 0.10 (10 cents). Check your power bill for the precise cost.

The energy used to charge a cell phone is not particularly substantial. Even if you leave a charger plugged in without a device that consumes half a watt continuously for a whole year, it will only cost you 44 cents at a rate of 10 cents per kWh. Unplugging your phone charger may help you save a little energy.
