Free calculators and scenario guides estimate portable power station runtimes and solar-generator sizing using sourced device and product data.

Landing page captured for the 2026-10-13 issue.

For: Campers, RV owners, and people planning backup power
Worth noticing: The comparison pages include a discrepancy table tracing conflicting search-result claims to official sources and the site's conclusion.

Field notes

The runtime tool can work in either direction: estimate a station's runtime for a device or estimate the capacity needed. A separate solar-sizing tool takes a daily appliance list and estimates battery, inverter peak, and array size. The homepage labels the data v0.2.0, dated 2026-08-09, and distinguishes sourced device and station figures from generic appliance values marked illustrative.
