The short answer
EcoFlow DELTA 3 Max costs $1900 less. Whether that gap is worth closing depends on what you need to run.
- Mango Power E holds 73% more energy (3533Wh vs 2048Wh), so it runs the same load proportionally longer.
- Mango Power E has 1200W more surge headroom (6000W vs 4800W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 3 Max is 18.0 lb lighter (55.1 lb vs 73.1 lb).
- EcoFlow DELTA 3 Max is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.

The value leader in the 2kWh class. Same 4800W surge as the DELTA 2 Max at $500 less, with 1000 more cycles.
