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.
Cell Phone Charger electricity usage
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.
