FAQ
What if the label only shows W?
Enter the watt value directly; the tool converts it to kW.
Is it accurate for inverter or cycling appliances?
Actual use varies. Use average wattage or energy-label data for estimates.
Does it include tiered electricity pricing?
The first release uses one price per kWh for comparing relative appliance costs.
Can I use this outside Taiwan?
Most calculations can be used anywhere by entering local values. If a tool mentions local rules or document specs, verify them with your local source.
