Specs
| Rated capacity | 2,764.8 Wh[source]Source noteUS manual V1.0 spec table: 'Battery Capacity 2,764.8Wh (51.2V/54Ah)'. |
|---|---|
| Usable capacity (AC) | Not publishedSource noteNo 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. |
| Battery chemistry | LiFePO4[source]Source noteManual spec table: 'Battery Type LiFePO4'. |
| AC continuous output | 3,840 W[source]Source noteManual 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 | Not publishedSource noteNo 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. |
| AC outlets | 6[source]Source noteManual spec table: '4 × AC Outlet (NEMA 5-20R)', '1 × AC Outlet (NEMA TT-30R)', '1 × AC Outlet (NEMA 14-50R)'. A seventh port, '1 × AC Output (P050A)', works only with the Hub A1 and is not counted. |
| UPS / EPS switchover | 20 ms[source]Source noteManual 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. |
| Expandable | Yes[source]Source noteManual 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'. |
| Max expanded capacity | 19,353.6 Wh[source]Source noteManual: 'connect to up to 6 B300K batteries for a maximum capacity of 19,353.6Wh'. The product page FAQ gives 21,196.8 Wh with 6 x B300/B300S (now discontinued). The B500K page FAQ allows 'Up to 6 B500K batteries' on the Apex 300 (about 33.5 kWh, not stated by BLUETTI as a total). Three units in parallel through the Hub A1 reach '58,060.8Wh'. |
| AC charging | 3,840 W[source]Source noteManual 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 | 2,400 W[source]Source noteOfficial 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. |
| Cycle life | 6,000 cycles to 80% capacity[source]Source noteProduct page: 'With the EnerBalance AI system, enjoy up to 6,000 cycles with 80% capacity retention.' |
| Weight | 83.78 lb[source]Source noteManual spec table: 'About 38kg (83.78lbs)'. |
| Warranty | Not publishedSource noteNot 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. |
| Idle draw | 19.5 W[source]Source noteESS News: 'An idle Apex 300, with inverters on, consumed around 19.5 W'. The voltage version is not stated. The Solar Lab found 'an idle draw of right around 20W'. The lower figure is used. BLUETTI's manual says 'about 20W'. |
| List price | $1,699[source]Source noteRegular (strikethrough) price $1,699.00, sale price $1,499.00 (US$200 off), seen 2026-10-19, in stock. An Apex 300 + B300K bundle is offered at $2,599. |

Runtime = 2,212 Wh usable (est. 80% of rated) ÷ the appliance's average draw. Fridges and freezers average their daily energy use; everything else counts as running the whole time. "No" means the load exceeds this model's continuous output or surge rating. Methodology.
Recharge with solar
Solar input: 12–60 V, 20 A, up to 2,400 W (XT60).Manual spec table: 'DC Input (2 × XT60PM-M)'. The FAQ says MC4 panels connect with an 'MC4-to-XT60' cable (sold separately).Manual spec table: 'DC Input (2 × XT60PM-M)'. Each port takes up to 1,200 W. Panels that fit, fastest first, one panel at a time; days use Dallas, TX's sun (5.4 peak hours a day on average, 4.37 in December). Two or more panels charge faster, up to this station's 2,400 W input limit.

Real-world watts = panel rating capped by this input's current limit (× the panel's voltage at max power) and maximum solar input, × 75%. Peak-sun hours to full = rated capacity (2,764.8 Wh, since charging fills the whole battery) ÷ real-world watts; days = those hours ÷ peak sun hours per day. Sunnier and cloudier cities are on each panel's page; full method in the methodology.

Usable capacity = this station's usable capacity + each battery's independently measured usable capacity, or 80% of its rated capacity where no test exists ("est."). Runtime uses the same formula as everywhere else on the site. Battery specs come from the brand's official pages.
