EcoFlow DELTA 2 vs Jackery Explorer 1500 Ultra
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 2 costs $300 less. Whether that gap is worth closing depends on what you need to run.
- Jackery Explorer 1500 Ultra holds 50% more energy (1536Wh vs 1024Wh), so it runs the same load proportionally longer.
- Jackery Explorer 1500 Ultra has 1400W more surge headroom (3600W vs 2200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 1500 Ultra is 0.5 lb lighter (26.5 lb vs 27 lb).
- Jackery Explorer 1500 Ultra is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA 2
The value pick in the 1kWh class. Cheaper than the Anker C1000 with nearly identical capacity — but check the surge number before you buy.
Best for: Budget-conscious buyers running electronics and a fridge, with no motor-driven loads.
Where it falls short:
- X-Boost tops out at 2200W — the least surge headroom of any 1kWh unit we list
- 80-minute recharge is slower than Anker's 58
Jackery Explorer 1500 Ultra
The portability record-holder: 1536Wh at 26.5 lb, lighter than most 1kWh units. You pay $200 over the 1500 v2 for that weight saving.
Best for: Van lifers and overlanders where every pound is negotiated.
Where it falls short:
- 1800W output is lower than the cheaper 1500 v2's 2000W
- $1199 is a premium for weight alone
