July 30, 2026 I built a free Generator Size Calculator to help people choose the right generator

Hi everyone! 👋

I'm the founder of Generator Fixer, where we help people with generator maintenance, repair, and free online tools.

We recently built a free Generator Size Calculator to help homeowners, RV owners, and professionals choose the correct generator based on their power needs.

I'd love your feedback on the tool. If you have any suggestions or ideas for improvements, I'd really appreciate hearing them.

Thanks! 😊

    Love the clarity — very intent-driven use case. Have you looked at capturing users post-calculation (quotes, suppliers, installs)? That’s where a lot of hidden value usually sits
