Jackery Explorer 300 Plus vs EcoFlow DELTA 3 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 $450 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Plus holds 256% more energy (1024Wh vs 288Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Plus has 3000W more surge headroom (3600W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 300 Plus is 20.4 lb lighter (8.27 lb vs 28.7 lb).
- EcoFlow DELTA 3 Plus is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Jackery Explorer 300 Plus
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
EcoFlow DELTA 3 Plus
The DELTA 3 with a $100 premium for smart-home integration and faster UPS switching. Same battery, same surge.
Best for: Home-office setups where a desktop or NAS can't tolerate a power blip.
Where it falls short:
- $100 more for features many buyers never use
- Same 1024Wh as the cheaper DELTA 3
