About & privacy
How this independent site works and what it does not claim.
What this site is for
Independent energy calculators and sizing guides for RV, van, camping and home backup power: batteries, solar, inverters, battery-versus-generator choices and emergency outage planning.
Editorial method: show assumptions, give reproducible formulas, link to the original source when using an external product fact, distinguish merchant claims from independent measurements, and correct errors promptly. There are no fabricated authors or lab tests.
Privacy: calculator inputs stay in your browser. No signup, visitor account or advertising is required. Production analytics may be enabled only with site configuration and visitor consent; our events contain page, tool and CTA identifiers, never the entered calculator values. No third-party analytics are loaded in the default preview.
If you accept analytics, Google Analytics measures page visits and tool or link interactions using analytics cookies. Your choice is stored in your browser. Use Analytics choices in the footer to change your decision or withdraw consent. Calculator entries and exported plans are never included in our analytics events. Google privacy policy.
