The EcoFlow RIVER 3 Max Series delivers flexible, expandable portable power for campers, photographers, drone pilots, remote workers, and anyone needing lightweight home or travel backup. Built around the compact RIVER 3 Plus power station, the Max and Max Plus configurations add wire-free Extra Batteries for extended runtime in the field.
Whether you’re powering laptops, camera equipment, monitors, drones, Starlink, lighting, tablets, or small appliances, the RIVER 3 Max Series is designed to keep you connected and productive anywhere. With a 600W AC output (1200W with X-Boost™) and EcoFlow’s long-lasting LFP battery chemistry, you get stable, clean power that performs reliably season after season.
The RIVER 3 platform recharges from 0–100% in just 60 minutes using AC input, or in as fast as 1.5 hours with solar. Quiet operation at <30 dB makes it ideal for both outdoor use and shared spaces. For extended off-grid sessions, creators and explorers can hot-swap Extra Batteries, allowing continuous operation for photography, video shoots, remote work, or multi-day camping.
