Quick answer: The EcoFlow DELTA Pro 3 has 1,024Wh more nominal capacity (4,096Wh vs. 3,072Wh); the EcoFlow DELTA Pro 3 lists more continuous AC output (4,000W vs. 3,600W); the Jackery Explorer 3000 v2 is lighter (59.5 lb vs. 113.54 lb). At a steady 1000W load our model estimates 2.3 h for the Jackery 3000 v2 and 3.1 h for the EcoFlow DELTA Pro 3. There is no universal winner: your loads, charging plan and the price of equivalent bundles decide.
Where they differ
Choose the Jackery Explorer 3000 v2 if…
- weight matters when you move it (54.0 lb lighter)
- energy per kilogram matters to you
Choose the EcoFlow DELTA Pro 3 if…
- you want more stored energy (1,024Wh more)
- you need to run heavier loads at once (4,000W continuous)
- you start motors or compressors (surge 8,000W published)
- you want more AC outlets (7)
- you need 240V output
- you plan to recharge from solar (2,600W max input vs. 1,000W)
- a longer warranty matters (5 years)
- you use it as a UPS for sensitive equipment (10 ms switchover)
- you prefer a cycle rating to a higher end point (80% remaining)
Read the cycle ratings carefully
The two manufacturers do not rate battery life to the same end point: Jackery Explorer 3000 v2 states 4,000 to 70%, EcoFlow DELTA Pro 3 states 4,000 to 80%. A rating to 70% remaining capacity is not directly comparable with one to 80%.
Notes from the manufacturer pages
- Jackery Explorer 3000 v2: Jackery's product page lists 400W solar input and 3 outlets; its help center lists 1,000W dual-port and 5 outlets.
- EcoFlow DELTA Pro 3: 120V/240V output. 6,000W with X-Boost for suitable loads.
Check your own loads
Capacity decides how long; continuous output decides what can run at once; surge decides whether motors and compressors start. Put your appliances into the tools below with either model preselected, and compare delivered prices for equivalent bundles before you buy.
