Where these rank
Quick answers
- Is the Bluetti AC180 better than the EcoFlow DELTA 3?
- EcoFlow DELTA 3 is the better station: the overall scores are close, but it wins warranty and track record, weight and noise — every dimension that separates them.
- Which has more usable capacity, the Bluetti AC180 or EcoFlow DELTA 3?
- The Bluetti AC180, by 80 Wh — 950 Wh versus 870 Wh, a 9% advantage. At a 60 W load that is roughly 1.3 extra hours before the battery is empty. Both figures are estimated AC-delivered energy, not the nameplate battery rating — the watt-hours that actually reach your devices, which is always less than the number on the box.
- Which has more AC output, the Bluetti AC180 or EcoFlow DELTA 3?
- Neither — both are rated 1,800 W continuous, so any load one can run, the other can too. Surge headroom follows the same order: 2,700 W against 3,600 W, and surge is what decides whether a compressor or pump actually starts.
- How does runtime compare between the Bluetti AC180 and EcoFlow DELTA 3?
- On the same sourced load — a refrigerator (full-size) — the Bluetti AC180 runs longer: 15.1 hours against 13.8. These are planning estimates from each model's AC-delivered capacity, not stopwatch tests; real duty cycle and temperature move them.
- Which is lighter, the Bluetti AC180 or EcoFlow DELTA 3?
- The EcoFlow DELTA 3, by 3.5 kg (12.5 kg versus 16 kg). Both weights are manufacturer figures for the bare unit; cables and a solar panel add to whatever you actually carry.
- Which model should I buy for my use case?
- On the sub-scores that describe each use case: the Bluetti AC180 for home backup; the EcoFlow DELTA 3 for cpap & bedroom, camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
