BLUETTIAC180VSEcoFlowDELTA 3 Plus
Both list 1,800W continuous output. AC180 adds 128Wh of rated capacity; DELTA 3 Plus is about 3.5kg lighter, doubles the total solar ceiling and provides two 140W USB-C outputs instead of one 100W port.
The documented differences
Green marks the numeric advantage for that row only. Connector and transfer-mode rows deliberately have no winner.
| Specification | BLUETTI AC180 | EcoFlow DELTA 3 Plus | Interpretation |
|---|---|---|---|
| Rated capacity | 1,152WhAdvantage | 1,024Wh | Higher label capacity; usable energy is lower. |
| Continuous AC output | 1,800WTie | 1,800WTie | Ordinary continuous output, not a lifting mode. |
| Maximum solar input | 500W | 1,000WAdvantage | A ceiling, not proof that a panel array is compatible. |
| Published weight | 16kg | 12.5kgAdvantage | Lower is marked as the metric advantage. |
| USB-C output | 1 × 100W | 2 × 140W | Port count and per-port ceiling both matter. |
| Solar path | MC4 → DC7909 | 2 × XT60i | Neither connector is universally better. |
| Transfer mode | ≤20ms transfer | 10ms standby UPS | 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.
BLUETTI AC180
Choose AC180 when the extra battery capacity is more useful than carrying weight, dual solar inputs or higher-power USB-C charging.
EcoFlow DELTA 3 Plus
Choose DELTA 3 Plus for a lighter solar-heavy or dual-laptop setup where 1,024Wh is enough and two independent 500W solar inputs are valuable.
The model name is not the whole product.
AC180 Power Lifting is limited to compatible resistive loads and is not ordinary inverter output. Both families have regional AC versions, so compare the locally sold hardware rather than the name alone.
