| Rated capacity | 2,048 Wh[source]Spec table: 'Battery Capacity 2,048Wh (51.2V, 40Ah)'. BLUETTI's site menu links to this page. A second US handle (/products/ac200l) has the same title but shows no spec content. | 2,048 Wh[source]Spec table: 'Capacity 2048Wh'. |
| Usable capacity (measured) | 1,680 Wh[source]nextpit.de (EU 230 V unit) measured 2,217 Wh in and 1.68 kWh usable. Trusted Reviews (UK 230 V unit) measured 1.77 kWh at about 2.4 kW, 1.9 kWh at 1,050 W and 1.76 kWh at 200 W. The lower figure is used. No US 120 V discharge test was found. | 1,800 Wh[source]StorageReview measured 1,800 Wh through the AC inverter at a 350 W load (120 V unit).

| AC surge output | 3,600 W[source]Spec table: 'Surge Power: 3,600W'. The official manual V3.0 gives an overload table instead: 2,520-3,000W for 2 min, 3,000-3,600W for 5 s, >3,600W for 0.5 s. | 4,800 W[source]Spec table and user manual both say 'surge 4,800W'. Marketing text on the same page cites 'up to 3400W' (that is the X-Boost figure, not surge). |
| 240 V output | No[source]Outlets are 120 V only ('4 x 120V/20A Outlets, 1 x 120V/30A NEMA TT-30'); the manual lists AC output 'Voltage 120VAC'.

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.
