EcoFlow DELTA 1300 vs Ampace Andes 1500
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
These two cost the same, so the decision comes down to what you're powering.
- Ampace Andes 1500 holds 16% more energy (1462Wh vs 1260Wh), so it runs the same load proportionally longer.
- Ampace Andes 1500 has 300W more surge headroom (3600W vs 3300W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 1300 is 5.9 lb lighter (30.9 lb vs 36.8 lb).
- Ampace Andes 1500 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Ampace Andes 1500 is rated for 3,000 cycles vs 800 — meaningful if you cycle it daily.
We'd skip the EcoFlow DELTA 1300 in this matchup. It costs $0 more than the Ampace Andes 1500 while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
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
Backed by an Amperex/CATL cell pedigree, the Andes 1500 stands out on charge speed — 0-80% in well under an hour — and a light 36.8 lb for 1.5kWh.
Best for: Buyers who prize fast charging and low weight at 1.5kWh.
Where it falls short:
- Newer brand with a thinner track record
- Not expandable
