|---|---|---|
| Rated capacity | 2,048 Wh[source]Specs 'Cell Capacity 51.2V / 40000mAh / 2,048Wh'. Model A1783; not the same product as the S2000 or F2000. | 2,764.8 Wh[source]US manual V1.0 spec table: 'Battery Capacity 2,764.8Wh (51.2V/54Ah)'. |
| Usable capacity (measured) | 1,600 Wh[source]Notebookcheck drew 'a good 1,600 Wh' at a ~200 W continuous load (just under 79%), and about 1,850 Wh at 1,800 W. That was the European 230 V version; The Solar Lab (US unit) reported ~89% efficiency but no Wh figure. | Not publishedNo independent measured capacity found (searched 2026-10-19). The Solar Lab gives only about 85% efficiency, ESS News gives no Wh figure, and CleanTechnica's test page did not load. A Bikman Tech figure (41 minutes at 3,840 W) comes from a retailer blog without a Wh result. |
| AC continuous output | 2,400 W[source]'AC Output (NEMA 5-20R) 120V~ 20A Max, 60Hz, 2400W Max'. | 3,840 W[source]Manual spec table: 4 x NEMA 5-20R '3,840W Max.'; the NEMA 14-50R '3840W Max.'; the TT-30R '3600W Max.'. In 240 V mode the 5-20R outlets are limited to '16A Max. each port (Every Two Ports: 1920W Max.)'. |
| AC surge output | 4,000 W[source]Specs 'Peak Power 4000W'. | Not publishedNo surge rating in the US manual or on the US product page (searched 2026-10-19). The page's '7,680W Lifting Power' is Power Lifting mode, which the manual says is for 'pure resistive loads like kettles, electric blankets, hairdryers'. BLUETTI's Amazon title calls 7,680 W a surge, but Amazon is not used as a source. |
| 240 V output | No[source]All AC outputs are 120 V: 'AC Output (NEMA 5-20R) 120V~ 20A Max, 60Hz' and 'AC Output (TT-30R) 120V~ 20A Max, 60Hz'. | Yes[source]A single unit outputs 120/240 V split phase: the NEMA 14-50R in 'Output (Voltage Selector: 240V)' mode gives '(Discharge Only): 120V/240V 50/60Hz, 16A Max.' and '(Bypass Mode): 120V/240V 50/60Hz, 50A Max.' The product page says 'power both 120V and 240V devices simultaneously'. The 5-20R and TT-30R outlets stay 120 V. |
| Battery chemistry | LiFePO4[source]Specs 'Battery Type LFP'. | LiFePO4[source]Manual spec table: 'Battery Type LiFePO4'. |
| Cycle life | 4,000 cycles to 80% capacity[source]Spec table 'Cycle Life 4000 Cycles'; comparison table '4,000 Cycles to 80% Capacity'. The page's structured spec data conflicts with '3000+ Cycles'. | 6,000 cycles to 80% capacity[source]Product page: 'With the EnerBalance AI system, enjoy up to 6,000 cycles with 80% capacity retention.' |
| AC charging | 1,800 W[source]US spec 'AC Input 120V~ 15A Max, 1800W Max, 12A (Continuous)'; 100% in 88 min on AC alone. AC + solar together reach 2,600 W (100% in 58 min). The EU version charges at up to 2,300 W. | 3,840 W[source]Manual spec table: 'AC Charging 3,840W Max. (80% in 45 mins ...)'. The standard 'AC charging input port' is limited to '120V ... 15A Max. 1,800W Max. (Charging + Bypass)'. 3,840 W Turbo charging needs the P050A input with the optional TT-30P or L14-50P cable. FAQ: Standard up to 1,440 W, Silent up to 500 W. |
| Max solar input | 800 W[source]'PV /XT-60i Input 11-60V⎓17A Max, 800W'. | 2,400 W[source]Official FAQ Q9: 'Direct input via 2 XT60 ports Each input port supports up to 1,200W (12V-60V*, 20A Max.), totaling 2,400W.' The optional SolarX 4K adds high-voltage input (500 V max) for up to 6,400 W in total. |
| Expandable | Yes[source]'Up to 4kWh Expandable Capacity' with one BP2000 (Gen 2) expansion battery. | Yes[source]Manual section 9: 'Use the battery expansion cables to connect to up to 6 B300K batteries'. The manual also says it 'is compatible with both B300 and B300S battery packs'. |
| UPS / EPS switchover | 10 ms[source]Specs 'UPS 10 ms'. | 20 ms[source]Manual section 7: switches 'within 0 ms or 20ms with specific outlets'. Note: 'When the output voltage switches to 120V, both are 20ms.' 0 ms applies only in 240 V mode on the two left 5-20R outlets, with the grid connected through the 15 A AC input. The product page advertises '0ms UPS switchover'. The general 20 ms figure is used. |
| Weight | 41.7 lb[source]Comparison table '41.7 lb (18.9 kg)'; spec table 'Net Weight 18.9 kg'. Structured spec data says '41 lb'. | 83.78 lb[source]Manual spec table: 'About 38kg (83.78lbs)'. |
| Warranty | 5 years[source]From the page's structured spec data ('Warranty: 5 Years'); the visible page only says 'Hassle-Free Warranty' and '10 Year Lifespan'. | Not publishedNot stated on the US product page, US support page or US manual (searched 2026-10-19). The US warranty policy only says portable power stations get '24 months to 72 months'. BLUETTI's Australian page lists a 5-year warranty, but that is not a US source. |

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.
