Running cost at a glance
EPREL lists 10 W in on mode for this 4-inch screen. That is not physically possible, so the registered value is most likely an entry error and we do not calculate a running cost from it. Check the official label: EU energy label (PDF)
Your country and usage
- Electricity at €0.2896 per kWh (household price with taxes, Eurostat 2025-S2).
- 210 g CO₂e per kWh generated in 2023 (European Environment Agency). Counts use only, not manufacturing.
We assume prices stay the same over the years.
