EcoFlow DELTA 3 Plus vs Jackery Explorer 500
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 500 costs $250 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Plus holds 98% more energy (1024Wh vs 518Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Plus has 2600W more surge headroom (3600W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 500 is 15.4 lb lighter (13.3 lb vs 28.7 lb).
- EcoFlow DELTA 3 Plus uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 3 Plus is rated for 4,000 cycles vs 500 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the Jackery Explorer 500. Its NMC cells are rated for 500 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
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
A long-running compact that's now firmly dated: one AC outlet, no USB-C, Li-ion cells and a very slow recharge. Only its ubiquity keeps it around.
Best for: Light, occasional device charging when found cheap.
Where it falls short:
- ~500 cycles
- One AC outlet, no USB-C
- 7.5-hour recharge
