EcoFlow DELTA 2 Max vs Jackery Explorer 1000 v2
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
Jackery Explorer 1000 v2 costs $800 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 2 Max holds 91% more energy (2048Wh vs 1070Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 2 Max has 1800W more surge headroom (4800W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 1000 v2 is 26.2 lb lighter (23.8 lb vs 50 lb).
- Jackery Explorer 1000 v2 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
The surge sleeper. At 4800W it starts loads that stations twice its price can't — and most spec sheets bury that number behind the X-Boost figure.
Best for: Home backup where something with a compressor — fridge, freezer, window AC — has to start reliably.
Where it falls short:
- 50 lb is heavy for its capacity
- Marketing leads with the 3400W X-Boost number, which understates it
The lightest 1kWh unit here at 23.8 lb, with a 3000W surge that punches above the Anker and EcoFlow units it competes with.
Best for: Campers who want 1kWh but care about carrying weight and need surge headroom.
Where it falls short:
- Only 3 AC outlets
- Not expandable — what you buy is what you get
- 400W solar input trails the Anker C1000's 600W
