Editorial standards

We would rather say less and be right. Every guide and tool on Generator Watt Calculator follows these rules.

Sources we use

For appliance wattages we use published manufacturer reference charts (such as Champion Power Equipment’s generator wattage chart) and university extension publications (such as Virginia Cooperative Extension’s appliance energy guide). For safety we rely on the U.S. Consumer Product Safety Commission, CDC, OSHA, FEMA’s Ready.gov, and NFPA. For outage data we use the U.S. Energy Information Administration.

We cite the primary source whenever one exists: the statute, the agency page, the court rule, or the extension publication. News articles and industry groups are used only for context and are labeled as such. Each guide lists its sources at the bottom with links.

What we will not do

• We do not invent statistics, testimonials, reviews, expert quotes, or credentials.
• We do not present estimates as measurements. Where a number is a rule of thumb or a model, the page says so and explains the math.
• We do not accept payment to include, rank, or recommend anything in our guides.
• We never ask readers to click ads, and ads are always labeled “Advertisement.”

Tools and data

Each calculator shows its formula. Appliance wattages are editable defaults taken from the upper end of published ranges, so results lean toward enough power rather than too little. Your appliance’s nameplate always wins over our defaults.

Review and updates

Each guide shows the date it was last reviewed. We re-check sources when we learn a rule has changed and at least once a year. When a change matters to readers, we note it on the page.

Corrections

If you find a mistake, use the contact form and include the page and a source. Confirmed errors are fixed promptly, and substantive corrections are noted on the page with the date.

Limits

Wattage figures on this site are typical ranges from published manufacturer charts and extension guides, not measurements of your equipment. Check the nameplate or manual for each appliance and your generator. Connecting a generator to home wiring requires a transfer switch or interlock installed to code, usually by a licensed electrician. Never run a generator indoors or in a garage.
