How we evaluate products
Every review starts with the manufacturer's current spec sheet — capacity (Wh), continuous AC output (W), surge wattage, battery chemistry, solar input range, weight, port count, and warranty. We pull these directly from the brand's product page, not from older reposts that may show outdated firmware or revisions.
We then cross-reference those numbers against independent sources: third-party load tests where they exist, owner-reported runtime threads on subreddits like r/SolarDIY and r/preppers, and warranty/return data where it's been disclosed. Where a manufacturer claim materially disagrees with independent measurement (a common one is solar input under real conditions vs. lab specs), we flag it in the review.
Where we have hands-on time with a unit, we say so explicitly. Where we don't, we say that too. We do not pretend to have tested gear we haven't.
