The EcoFlow River Series is perfect for providing backup power to your smaller electronics, such as synthesizers, digital mixers, and wireless microphone equipment.
The EcoFlow RIVER 2 Max is designed for the band director who needs more than just a quick charge. With a 512Wh capacity and a 500W output, it’s a great solution for powering on-field synthesizer rigs, digital mixers, and wireless microphone systems.
Why the RIVER 2 Max is the Best Fit for Your Sideline:
- Power Your Performance: The 500W output (with a 1000W surge) can easily handle the power draw of synth rigs and digital mixers, ensuring your setup stays active from the first note of warm-ups to the final push of the show.
- Student-Friendly Portability: At just 13.4 lbs, it remains incredibly easy for any student to grab by the integrated handle and move during a quick set change or transition.
- Whisper-Quiet Focus: Operating at roughly 30dB, it is silent enough to sit directly next to your synth player or soloist without distracting the performers or judges.

Student Safety & School Compliance
- Zero Fumes & Gas-Free: Completely safe for use inside the band room during indoor rehearsals or for powering electronics inside an equipment trailer. No carbon monoxide or fire hazards.
- Eliminate Trip Hazards: By powering your gear locally on the field, you remove the need for long extension cords running across the track, keeping the path clear and safe for your staff and students.
- Safety Certified: The first power station in the world to earn the TÜV Rheinland safety certification, guaranteeing a high standard of reliability for your school program.
Reliability & Longevity
- A Decade of Use: Built with upgraded LFP (Lithium Iron Phosphate) battery chemistry that lasts for 3,000+ cycles. For most band programs, that’s 10 years of daily use before the battery capacity drops to 80%.
- 5-Year Warranty: EcoFlow offers an industry-leading warranty, ensuring your program’s investment is protected for years of marching seasons.
- Instant Backup: With a switchover speed of less than 30ms, your digital electronics won't reboot if the stadium power flickers, keeping your show running smoothly.
