About electric shaver running costs
Electric shavers use modest power for short periods or while charging. Battery capacity can help estimate energy per full charge.
Typical sizes: 5 W, 10 W, 20 W, 30 W.
How to spend less: Charge as needed and use the model’s rated input for a rough estimate.
What this estimate assumes
- The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
- Wattage is the typical label value, not a measured value. Check the label on your own appliance.
- The rate is an approximate residential average. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
- A month is 30 days and a year is 365 days.
