Rated capacity1,152 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]1024Wh 51.2V 20Ah. Not the same product as the DELTA 3 / DELTA 3 Plus / DELTA 3 Max.
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.Not publishedno independent test found. thesolarlab.com reports about 83% inverter efficiency but does not publish a measured Wh figure.

AC surge output2,700 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.3,600 W[source]'3600W surge output'. X-Boost (resistive loads up to 2600 W) is a separate feature. Some retailer listings give X-Boost as 2400 W; the official page says 2600 W.

ExpandableNo[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.Not publishedOfficial page does not state expandability. An independent review (thesolarlab.com) lists it as non-expandable.

Runtime = usable capacity ÷ average draw, the same formula for both models (no idle draw added to either), after checking continuous output and startup surge. Usable capacity is an independent test's measured figure, or 80% of rated where none exists. See the methodology.
