The short answer
EcoFlow DELTA 3 Plus costs $2250 less. Whether that gap is worth closing depends on what you need to run.
- Mango Power E holds 245% more energy (3533Wh vs 1024Wh), so it runs the same load proportionally longer.
- Mango Power E has 2400W more surge headroom (6000W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 3 Plus is 44.4 lb lighter (28.7 lb vs 73.1 lb).
- EcoFlow DELTA 3 Plus is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
