EcoFlow DELTA 2 Max vs Jackery Explorer 300 Plus
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 300 Plus costs $1300 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 2 Max holds 611% more energy (2048Wh vs 288Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 2 Max has 4200W more surge headroom (4800W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 300 Plus is 41.7 lb lighter (8.27 lb vs 50 lb).
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
A device charger, not a power station. At 8.27 lb and 288Wh it's for phones, laptops and a CPAP — nothing with a heating element or compressor.
Best for: CPAP users and travelers who need days of small-device power in a bag.
Where it falls short:
- 300W output rules out almost every appliance
- 288Wh is a single laptop-day of capacity
