- Worth noticing
- The site labels adjustable efficiency and headroom values as assumptions, and includes output-limit checks for power-station runtime estimates.
Field notes
The wattage preview includes examples ranging from refrigerators and air conditioners to routers and CPAP machines, with source links shown beside the entries. The site says home-lab figures from third-party sources are marked as estimates and that calculator assumptions can be changed. Its disclaimer directs readers to equipment nameplates and manufacturer instructions, and excludes life-support or medical-device power planning.
