Why a "Spec Reality Score"?
Manufacturer specs are useful but optimistic. A "1,024 Wh" battery typically delivers ~960 Wh of usable energy under realistic load. A "1,800 W inverter" might cut out at 1,750 W when the air conditioner kicks on. The gap matters when you're planning a 12-hour CPAP overnight or a multi-day blackout.
Our Spec Reality Score compares manufacturer claims against actual third-party test data (YouTube reviewers, professional labs). A score above 90 means real-world numbers track within 5% of the spec sheet. A score under 80 means notable inflation. See the methodology →
