How We Test & Compare Power Stations

We track 123 power station models across 6 brand ecosystems, with 19 spec fields per unit. Specs are pulled from each manufacturer's published spec sheets and product pages, then cross-checked against retailer listings before a unit enters the database.

Prices are captured from each brand's official store, and we record the listed price as-is — checked periodically, not live. A price on this site is the most recent one we captured, not a real-time feed, and it can lag a flash sale by days.

Newest model added to the catalog: 2026-07-18. (That's the newest addition date, not a claim that every spec was re-verified on that day.)

Catalog additions and price checks happen on an ongoing basis, not a fixed schedule — new models are added when brands release them, and prices are re-captured periodically from official stores. When a spec or price changes, every score that depends on it recomputes automatically.

The aggregate figures from the full catalog — median prices, chemistry split, per-class and per-brand medians — are published on our data page. This page explains how the numbers are produced; that page is the numbers themselves. The complete row-level dataset is available on request.

Spot a spec we got wrong? Email hello@stationarena.com with the model and a source (a spec sheet or product page is ideal). When a correction is confirmed, we update the database, and every page and score that used the old value updates with it. We don't quietly re-score products: a confirmed correction changes the data, not the methodology.

We're equally upfront about what we can't verify — manufacturer cycle-life claims, long-term degradation, warranty-claim experience. That list lives in the "What We Don't Test (Yet)" section of our About page.
