Printed as the row "RIVER Pro Extra Battery | 24" in the Extra Battery Series of the warranty table in the EcoFlow Limited Warranty Policy - United States (us.ecoflow.com/pages/warranty-policy, "Updated on: [ 20,10,2025 ]"), captured on October 23, 2026. The table's column is headed "Warranty Period (refer to months, unless specified)", so "24" is 24 months, shown here as 2 years. The policy says the limited warranty "begins on the date of delivery to the original consumer purchaser and is valid only on products purchased and used in the United States", applies to the original consumer purchase with proof of purchase and/or proof of delivery, and gives standard warranty coverage in the contiguous United States only. The table names no cycle limit, throughput or capacity retention for this item. The record is documented from EcoFlow's US store page for this battery (us.ecoflow.com/products/river-pro-extra-battery), so this US term applies to it as sold in the United States.

Own one? A verified review needs a receipt and a serial number photo, and counts 19× in the owner rating.
The Evidence score uses the priorities you choose. It counts published documents, such as certificates and warranty terms, and it compares a documented figure with the best documented figure of the same kind. It does not count owner reviews, and it is not a verdict on product quality or on how many people have reviewed it. A low score can mean little is documented, or that a documented figure is below the best of its kind. Undisclosed data scores 0.
Missing details. This number counts only the evidence recorded so far. The source review for this product is not finished, or the maker has not disclosed enough, so the number can only go up.
Missing for this product: Certificates evidence needed; Warranty energy disclosure evidence needed; Cell model disclosure evidence needed.
Format not recorded · Expansion · Rated capacity
The warranty term and the lifetime energy are each scored against the best documented value for an expansion battery: a value earns its share of that best, times the weight. A documented value always earns points; an undisclosed one earns 0.
