Most "best power station" lists are an Amazon storefront with better copywriting. This one starts from the watt-hour and output numbers each brand actually publishes, and flags it plainly when an independent reviewer's measurement doesn't match the marketing page.
Pick the tier that matches what you're actually trying to power — a fridge through a multi-day outage is a different purchase than a phone and a headlamp for a weekend, and the biggest watt-hour number you can afford is usually the wrong answer to the wrong question.
