Data snapshot

Methodology — every formula, and what this data cannot tell you.

What size generator do you need?

Tick the appliances you need to keep running and the sizing tool sums their running watts, adds the largest starting surge, and recommends a size with headroom — then points at models that meet it.

Also: compare gasoline, propane and natural gas running costs

Size my generator

No open dataset exists for this category, so every record here was compiled by hand from manufacturer documentation and each one links to its source. Noise, runtime, transfer-switch readiness and the running-cost math are all included.
