EcoFlowDELTA 3 PlusVSEcoFlowDELTA 2
Capacity and ordinary AC output are tied in this dataset. DELTA 3 Plus doubles the published solar ceiling to 1,000W, raises both USB-C ports to 140W and documents a 10ms standby UPS; DELTA 2 is slightly lighter and keeps a simpler single-input solar path.
The documented differences
Green marks the numeric advantage for that row only. Connector and transfer-mode rows deliberately have no winner.
| Specification | EcoFlow DELTA 3 Plus | EcoFlow DELTA 2 | Interpretation |
|---|---|---|---|
| Rated capacity | 1,024WhTie | 1,024WhTie | Higher label capacity; usable energy is lower. |
| Continuous AC output | 1,800WTie | 1,800WTie | Ordinary continuous output, not a lifting mode. |
| Maximum solar input | 1,000WAdvantage | 500W | A ceiling, not proof that a panel array is compatible. |
| Published weight | 12.5kg | 12kgAdvantage | Lower is marked as the metric advantage. |
| USB-C output | 2 × 140W | 2 × 100W | Port count and per-port ceiling both matter. |
| Solar path | 2 × XT60i | XT60 / XT60i | Neither connector is universally better. |
| Transfer mode | 10ms standby UPS | EPS; verify load tolerance | Verify whether your exact load tolerates the transfer. |
Choose for the job,
not the badge.
These recommendations use the documented specifications above. They are not physical test results.
EcoFlow DELTA 3 Plus
Choose DELTA 3 Plus when faster solar replenishment, dual independent panel inputs, 140W USB-C or documented 10ms transfer behavior justify the newer platform.
EcoFlow DELTA 2
Choose DELTA 2 when its 1,024Wh and 1,800W fundamentals already fit and lower weight or a simpler existing XT60 setup matters more than the newer features.
The model name is not the whole product.
A shared brand and similar capacity do not make accessories or regional versions identical. Verify the exact solar lead, AC hardware and applicable certification mark on the United States 120V units being sold.
