The specific problems addressed by this website
A home appliance electricity consumption and cost estimator that discloses the calculation methods for power, runtime, duty cycle, and electricity price, and supports comparing two scenarios.
The tools and instructions on this site currently focus on "home computing." The user guide provides examples, input limitations, the meaning of results, and verification methods. These tools do not replace actual environment testing; results must be interpreted according to the instructions.
How to maintain content and computation
The tools were developed and verified by the site's maintainers; the articles are compiled by combining verified technical data, publicly available calculation methods, and examples designed by this site, and are edited using automated assistance. Source links, editorial suggestions, and hypothetical examples will be explained separately, and no fabricated real-world experiences, benefits, or usage data will be provided.
The date on the content indicates the time the description was checked, and does not imply that third-party services or standards will remain unchanged. Errors found will be corrected in calculations, examples, or descriptions, and the maintenance results will be recorded. You can provide non-sensitive examples that reproduce the problem via the contact page.
