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, app support and warranty for the unit being sold locally.
