EcoFlow DELTA 1300 vs Mango Power E
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
EcoFlow DELTA 1300 costs $2000 less. Whether that gap is worth closing depends on what you need to run.
- Mango Power E holds 180% more energy (3533Wh vs 1260Wh), so it runs the same load proportionally longer.
- Mango Power E has 2700W more surge headroom (6000W vs 3300W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 1300 is 42.2 lb lighter (30.9 lb vs 73.1 lb).
- Mango Power E uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Mango Power E is rated for 3,000 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA 1300. Its NMC cells are rated for 800 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
The original DELTA that put EcoFlow on the map. Fast-charging and high-surge for its day, but the NMC battery and lack of USB-C now show its age.
Best for: Bargain hunters who find it heavily discounted.
Where it falls short:
- NMC — ~800 cycles
- No USB-C PD
- 2-year warranty
A polished 3.5kWh home unit with a standout 10-year warranty. The catch is a relatively low 660W solar input for the capacity.
Best for: Home-backup buyers who want a long warranty and lots of capacity.
Where it falls short:
- 660W solar input is low for 3.5kWh
- 73.1 lb
