Hi Product Hunt! I created PowerMatchLab because choosing a portable power station is often harder than it should be. Product pages advertise large capacity and output numbers, but they rarely help someone answer the practical question: “Will this actually power my devices for as long as I need?” PowerMatchLab lets you enter your real appliances and usage time, calculates the required battery capacity, continuous output and startup surge, and compares the result against a catalog of 49 portable power stations. The platform also includes specialized calculators for refrigerators, CPAP machines, Starlink, RV appliances, RV air conditioners and home backup, alongside side-by-side product comparisons. The formulas and assumptions are visible and adjustable, manufacturer-sourced specifications are identified, and missing information remains marked as not verified. PowerMatchLab is free to use. It has no paid placements, and affiliate relationships never influence rankings or calculations. I would genuinely appreciate your feedback: which calculation, comparison or planning feature would make PowerMatchLab more useful to you?
