1) Audience-fit first: We map every recommendation to a specific reader profile — use case (camping, home backup, RV, emergency prep), budget tier, power requirements, and portability needs.
2) Practical performance over headline specs: We weight real-world factors — battery chemistry, inverter efficiency, solar charging speed, and build quality — more heavily than peak wattage numbers alone.
3) Scenario-based ranking: We rank by use case (best under $1,000, best for off-grid, best for emergencies) rather than producing a single "winner" that fits no real reader.
4) Specification verification: Capacity (Wh), AC output (W), solar input (W), battery chemistry, weight, and dimensions are verified against the manufacturer's current product page before publishing or updating a recommendation.
5) Pricing accuracy: Where technically possible, live prices are pulled from Amazon at the time of the page visit. Base recommendations use manufacturer MSRP or typical street price to ensure fairness across time.
6) Update cadence: Buying guides are reviewed at minimum quarterly and whenever a featured product is discontinued, replaced, or significantly re-priced.
