EcoFlow Expands U.S. Brick and Mortar Presence with Costco Collaboration

New RIVER 3 Plus Wireless power station arrives at around 500 U.S. Costco locations, marking company's largest in-store rollout

SEATTLE, May 15, 2025 /PRNewswire/ -- EcoFlow, a leading provider of eco-friendly portable power solutions, today announced a major in-store collaboration with Costco Whole Corporation (Costco) as part of the company's effort to make its products available in more places its customers shop. The rollout brings the new EcoFlow RIVER 3 Plus Wireless, an ultra-portable, expandable power station for adventure and everyday living, to around 500 Costco stores across the U.S.

EcoFlow products will now be available in more than 90% of all Costco locations, covering around 95% of states nationwide.

Weighing just over 10lbs., the RIVER 3 Plus Wireless offers 600W of output and includes a detachable EcoFlow RAPID power bank (5000mAh) for ultimate versatility. The unit's 286Wh storage capacity can also be more than doubled or tripled with optional expansion batteries providing premium flexibility for every power need.

Powering Up with Costco: A Milestone in Offline Reach

Since first teaming up in 2021, EcoFlow's relationship with Costco U.S. has steadily expanded with the growing popularity of cutting-edge portable power solutions with Americans. EcoFlow today offers at least twice as many product offerings at Costco compared to any other portable power brands.

"Our partnership with Costco has been instrumental in expanding our reach to households across the U.S., and we're committed to deepening that relationship," said Brian Essenmacher, head of North American business development at EcoFlow. "We chose RIVER 3 Plus Wireless for this milestone rollout based on the incredible momentum behind the RIVER 3 series, especially among those new to portable power solutions. It embodies what our customers value most and what this partnership is all about: bringing powerful, flexible, portable energy solutions to more people, easier than ever."
