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 3 Max is built for the program that simply needs more power. With an expanded 858Wh capacity and 600W of continuous output, it is the ideal "set-and-forget" power source for your electronic instruments. Whether you are running a complex multi-keyboard synthesizer station or providing a bulletproof backup power for your digital mixer and wireless racks, the RIVER 3 Max ensures your electronics system stays live from the lot to the field.

 

Why the RIVER 3 Max is a "Must-Have" for Your Program:

  • Extended Rehearsal Life: Thanks to the wire-free extra battery, you get up to double the runtime for your electronics, making it perfect for those 12-hour "all-day" Saturday rehearsals.

 

  • Professional-Grade UPS: With a lightning-fast 10ms switchover, your electronics are protected against stadium power flickers or extension cables getting unplugged. 

 

  • Clean, Silent Energy: Operating at whisper-quiet levels (less than 30dB), this unit sits silently on your cart. It won't distract your performers, audience members, or judges. The silent treatment never sounded so good.
