Terms of Use
Last updated: September 1, 2026
Acceptance of terms
By using Power Station Tools, you agree to these Terms of Use. If you do not agree, please do not use this site.
Estimates only — not a substitute for official specifications
Every calculation on this site is an estimate based on standard formulas and typical, orientative device wattages. Results do not replace the official specifications, manuals, or guidance provided by the manufacturer of your power station, solar generator, battery, or any appliance. Real-world performance can vary due to inverter efficiency, temperature, battery age and health, fluctuating device draw, and other factors outside this calculator's model.
No warranty
This site and its calculators are provided "as is," without warranties of any kind, express or implied, including but not limited to accuracy, reliability, or fitness for a particular purpose.
Not professional advice
Nothing on this site constitutes medical, electrical, safety, or other professional advice. In particular, if you depend on electrical medical equipment (such as a CPAP machine), consult your equipment provider or physician for guidance on backup power planning — do not rely solely on this calculator for medical device power planning.
Limitation of liability
To the fullest extent permitted by law, Power Station Tools and its operators are not liable for any direct, indirect, incidental, or consequential damages arising from your use of, or inability to use, this site or its calculators — including but not limited to damages related to food spoilage, equipment failure, or medical device interruption.
Intellectual property
The design, code, and original written content of this site are the property of Power Station Tools unless otherwise noted. You may not copy or redistribute substantial portions of this site without permission.
Changes to the service
We may modify, suspend, or discontinue any part of this site at any time without notice.
Changes to these terms
We may update these Terms of Use from time to time. Continued use of the site after changes constitutes acceptance of the revised terms.
