EcoFlow Delta 3 Max portable power station front display and outlets
The EcoFlow Delta 3 Max is built for the program that needs professional-grade power without the logistical headache of combustion fuel generators and long cable runs. With a massive 2048Wh capacity and a 3000W output, this unit can easily drive your entire front ensemble audio system, including multiple powered speakers, subwoofers, and digital mixing consoles.
 
Why the Delta 3 Max is the Director’s Choice: 
  • All-Day Performance: With 2kWh of storage, you can run a full professional audio setup for a 6–8 hour rehearsal block or multiple Saturday competition performances on a single charge.
 
  • Silent Sideline: At only 30dB, it operates more quietly than a whisper. Your front ensemble microphones won’t pick up any hum, ensuring a clean, professional sound for your performers.
 
  • Zero-Maintenance Safety: Battery power means zero fumes, zero gasoline, and zero pull-cords. It is completely safe to use in the band room or on the sideline, keeping your focus on the music rather than the equipment.

  • Student Safety & School Compliance

    • Zero Fume Safety: Completely battery-powered, making it safe for use in the band room, enclosed trailers, or crowded stadiums. No carbon monoxide risk.
    • No Gasoline Liability: Eliminate the need to transport or store flammable gasoline on school property or in equipment trucks.

    • IP65 Battery Protection: The internal battery pack is IP65-rated, offering superior resistance to dust and moisture during misty morning rehearsals or humid summer camps.
    • 5-Year Warranty: EcoFlow provides one of the industry's longest warranties, ensuring your program's investment is protected for years to come.
