EcoFlow DELTA Pro 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
Ampace Andes 1500 costs $2200 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 146% more energy (3600Wh vs 1462Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 3600W more surge headroom (7200W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Ampace Andes 1500 is 62.2 lb lighter (36.8 lb vs 99 lb).
- EcoFlow DELTA Pro is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA Pro
The previous-generation flagship, now mostly worth buying on discount. The Pro 3 beats it on nearly every axis.
Best for: Bargain hunters who find it steeply discounted against the Pro 3.
Where it falls short:
- 99 lb and 165-minute recharge — both beaten by the Pro 3
- Aging platform; expect it to be phased out
Ampace Andes 1500
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
