Specs side by side
| Spec | BLUETTI AC180 | EcoFlow DELTA 2 |
|---|---|---|
| Rated capacity | 1,152 Wh[source]AC180 is 1,152 Wh; the AC180P (1,440 Wh) on the same page is a different variant. OutdoorGearLab notes BLUETTI has released the Elite 100 v2 as the AC180's successor. | 1,024 Wh[source]Specs tab: 'Capacity 1024 Wh'. Manual: '1,024Wh, 51.2V'. The official US info page still exists, but the us.ecoflow.com store URL (/products/delta-2-portable-power-station) now redirects to the DELTA 3, so the unit is no longer sold standalone on the official US store. |
| Usable capacity (measured) | 950 Wh[source]OutdoorGearLab measured 950 Wh at 80% load (82%). StorageReview measured 1,030 Wh at a 350 W load; the lower figure is used. | 850 Wh[source]StorageReview measured 0.85 kWh through AC at a 270 W load (120 V unit). EU 230 V units tested higher: nextpit 901 Wh at about 1,000 W; techtest.org 826 Wh (AC 125 W) and 903 Wh (AC 750 W). Lowest figure used. |
| AC continuous output | 1,800 W[source]4 x 120V/15A, 1800W in total. | 1,800 W[source]Specs tab: 'AC Output 6 ports, 1800W total (Surge 2700W)'. X-Boost is listed as 2400W on the specs tab but 2200W in the overview text and the user manual. |
| AC surge output | 2,700 W[source]Spec table 'Surge Power: 2700W'; the manual also says it 'can handle a surge of 2700W'. The same 2,700 W figure is used for Power Lifting Mode, which only applies to resistive heating loads. | 2,700 W[source]Specs tab and user manual agree: 'surge 2,700W'. |
| 240 V output | No[source]AC outlets: '4 x 120V/15A' ('4x120V(1800W Total)'); no 240V output listed. | No[source]Manual: 'AC (x6) Pure Sine Wave, 1,800W total (surge 2,700W), 120V~ (50Hz/60Hz)'. 120 V only. |
| Battery chemistry | LiFePO4[source] | LiFePO4[source]Specs tab: 'LFP (LiFePO4)'. |
| Cycle life | 3,500+ cycles to 80% original capacity[source] | 4,000 cycles to 80%+ capacity[source]Specs tab says '4000 cycles to 80%+ capacity'; the overview on the same page ('3000+ full charge and drain cycles') and the user manual ('3,000 cycles to 80% + capacity') say 3,000. Spec-tab value used per policy. |
| AC charging | 1,440 W[source]Turbo mode 1440 W (enabled in the app); standard mode 1000 W max. | 1,200 W[source]Official user manual V1.0: 'AC Charging X-Stream Fast Charging 1,200W max.' Not stated on the specs tab. |
| Max solar input | 500 W[source]500W Max., VOC 12-60VDC, 10A. | 500 W[source]Manual: 'Solar Charging 11-60V 15A Max, 500W Max'. The official overview also says 'up to 500W input'. |
| Expandable | No[source]Official FAQ: 'the AC180 doesn't support capacity expansion with B80, B230, or B300 batteries'; they can only charge it through Power Bank Mode. The page description's 'up to 4,224Wh' wording refers to that charging, not true expansion. | Yes[source]Specs tab: 'Support one DELTA 2 extra battery or DELTA Max extra battery'. Manual: 'A single DELTA 2 can connect up to 1 Smart Extra Battery'. |
| UPS / EPS switchover | 20 ms[source]Official user manual: 'Switching time 20ms'; Grid Enhancement mode must be off for UPS use. The product page does not state it. | 30 ms[source]Specs tab: 'UPS 30ms, EPS'. Manual: switches to battery 'within 30ms' and 'does not support 0ms switching'. |
| Weight | 35.3 lb[source]Spec table: 'About 16kg / 35.27lbs'. Official figures conflict: the same page's description says 37 lb / 17 kg and the user manual says 36.16 lb / 16.4 kg. | 27 lb[source]Specs tab: 'Net Weight (lb) Approx. 27' / 'Approx. 12' kg. Manual: 'Approximately 12 kg (27 lbs)'. |
