The differences that matter

  • Switchover: 20 ms with a gap (EPS) → 10 ms continuous (UPS): it matters for anything connected that cannot tolerate an interruption.
  • Maximum expansion: 6.144 kWh → 10 kWh: DELTA 3 Max Plus leaves more room for a battery that grows.
  • Charging 0-80%: 53 minutes → 68 minutes: DELTA 2 Max is ready again sooner.
  • Outputs: two 12 V and three USB-C up to 140 W (DELTA 3 Max Plus): you power those without going through the mains socket.

Which one to choose

Choose EcoFlow DELTA 2 Max if…

you recharge often and charging time matters, and you want five years of warranty and 3,000 declared cycles. The trade-off: a 4,800 W peak and a declared 20 ms switchover with a gap.

Choose EcoFlow DELTA 3 Max Plus if…

you need to start a load that peaks up to 6,000 W, or you want to take the battery to 10 kWh with extra packs; it also has two 12 V outputs, three USB-C up to 140 W and a declared 25 dB noise level. The trade-off: 68 minutes to reach 80% and a shorter warranty.
