Hey Product Hunt, I built BatteryRank because choosing a portable power station is much harder than it should be. Every brand presents capacity, output, charging speed, cycle life, weight, and pricing differently. A product with a larger advertised battery is not necessarily the better choice, and it can be difficult to tell whether a station will actually run a refrigerator, CPAP machine, camping setup, or essential devices during an outage. BatteryRank turns those specifications into practical comparisons and recommendations. You can: • Compare portable power stations side by side • Explore rankings for camping, home backup, RVs, CPAP use, and different budgets • See usable capacity, inverter output, charging speed, weight, lifespan, warranty, and value • Use sizing and runtime tools to understand what you actually need • Review the methodology behind every ranking The project started as a structured database of power-station specifications, but it evolved into a decision tool focused on answering the questions buyers actually have: What can this run? How long will it last? Is the extra capacity worth the weight and price? BatteryRank is free to use. Rankings are based on transparent engineering data rather than sponsored placement. I’d especially appreciate feedback on: 1. Whether the comparisons make the specifications easier to understand 2. Which sizing or runtime tool would be most useful next 3. Which brands or models are missing Thanks for checking it out. I’ll be here throughout launch day answering questions and reviewing every suggestion.
