About RV Watts

Last updated: September 3, 2026

RV Watts is a small, independent reference site. We build free, fast calculators and reference pages that answer one specific practical question at a time — the kind of question you need a real number for, not a paragraph of text.

What we make

• Calculators that run entirely in your browser. Your inputs never leave your device.
• Reference tables compiled from official and primary sources, with the source named on every page.
• Short guides that explain how a calculation works and when its assumptions break down.

How we work

Every page states its sources and assumptions. When we cite an official standard or a government agency, we link to it so you can check our work. See our Methodology & Sources page for the full policy.

How the site is funded

RV Watts is funded by advertising. We use Google AdSense, which may show ads based on your interests subject to your consent choices. Ads never influence our calculations, and we don't accept payment for placement inside results or tables. See our Privacy Policy for details.
