EcoFlow Delta Pro 3 portable power station display screen and outlets
Designed to power your entire front ensemble - including high-powered loudspeakers, digital mixers, and synths - the Delta Pro 3 delivers professional-grade, 4000W power in a staff-and-student-friendly package. Gone are the days of dragging extension cords across the practice field or dealing with the noise and fumes of a gas generator.
 
Why the Delta Pro 3 is a Game-Changer for Directors:
  • Silent Performance: At only 30dB, it is literally whisper-quiet. You can place it directly in, or next to, your sound cart without it interfering with your front ensemble microphones.
 
  • Massive Capability: With a 4kWh capacity and 4000W output, this unit can power a professional-level audio rig for an entire 8-hour rehearsal day or multiple Saturday performances without breaking a sweat.
 
  • Zero-Fume Safety: Because it is battery-powered, it produces zero carbon monoxide. It is safe to store in the band room, safe for your students to handle, and safe to use in crowded stadiums.

  • Student Safety & School Compliance

    • No Gasoline Required: Eliminate the need to store flammable fuel in school equipment trucks or storage closets.
    • Indoor-Safe Power: Unlike generators, this unit is safe to use in the band room during indoor rehearsals or in the equipment trailer during loading.
    • Sideline Hazard Reduction: By keeping the power source local to the front ensemble, you eliminate "trip-wire" extension cords running across the track or sideline.

  • Reliability & Longevity

    • Built to Last: Uses EV-grade LFP battery chemistry that retains 80% capacity even after 4,000 cycles—that’s over 10 years of marching seasons.
    • Weather Ready: The battery pack is IP65-rated, meaning it is resistant to water, dust, and impact.
    • Full Protection: Protected by EcoFlow’s X-Guard BMS, which monitors safety in real-time to prevent overheating or short circuits.
    • 5-Year Warranty: EcoFlow provides one of the industry's longest warranties, ensuring your program's investment is protected for years to come.
