💡 Energy-saving tip
Reduce unnecessarily high brightness and use automatic power-off features.
The calculation uses power × usage duration as an estimate. For devices whose power consumption varies during operation, actual electricity consumption may differ.

Understand the calculation
How does TinyTools calculate electricity costs?
TinyTools converts the device's power from watts to kilowatts and multiplies it by the usage time.
The calculated electricity consumption is then multiplied by your electricity price and usage frequency.
This is an estimate. For devices whose power consumption changes during operation, a measured consumption value is more accurate.

Reduce unnecessarily high brightness and use automatic power-off features.
