Specs side by side
| Spec | BLUETTI Apex 300 | EcoFlow DELTA 2 Max |
|---|---|---|
| Rated capacity | 2,764.8 Wh[source]US manual V1.0 spec table: 'Battery Capacity 2,764.8Wh (51.2V/54Ah)'. | 2,048 Wh[source]Spec table: 'Capacity 2048Wh'. |
| Usable capacity (measured) | 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. | 1,800 Wh[source]StorageReview measured 1,800 Wh through the AC inverter at a 350 W load (120 V unit). The Solar Lab reports 86% inverter efficiency but gives no Wh figure. |
| AC continuous output | 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.)'. | 2,400 W[source]Spec table: 'AC Output 6 outlets, 2400W total (Surge 4800W)'. X-Boost: 3,400 W. |
| AC surge output | 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. | 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 | 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. | No[source]Official manual: 'AC (x6) Pure sine wave, 2,400W total (surge 4,800W) 120V~ 50/60Hz'. 120 V only; the product page does not state outlet voltage. |
| Battery chemistry | LiFePO4[source]Manual spec table: 'Battery Type LiFePO4'. | LiFePO4[source]Spec table: 'LFP (LiFePO4 battery)'. |
| Cycle life | 6,000 cycles to 80% capacity[source]Product page: 'With the EnerBalance AI system, enjoy up to 6,000 cycles with 80% capacity retention.' | 3,000 cycles to 80%+ capacity[source]Spec table: '3000 cycles to 80+% capacity'. |
| AC charging | 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. | 1,800 W[source]Spec table: 'AC Charging X-stream Fast Charge 1800W, 15A'. Manual agrees ('X-Stream max. 1,800W 15A'). |
| Max solar input | 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. | 1,000 W[source]Spec table: '11-60V 15A, single port 500W; dual port 1,000W'. |
| Expandable | 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'. | Yes[source]Spec table: 'Supports up to two DELTA 2 Max Smart Extra Batteries / DELTA Max Smart Extra Battery'. |
| UPS / EPS switchover | 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. | 20 ms[source]Official US product page: '<20ms UPS Auto-Switch' and 'updated 20 ms UPS feature'. The original user manual V1.0 says 'within 30ms'. Not listed in the us.ecoflow.com spec table. |
| Weight | 83.78 lb[source]Manual spec table: 'About 38kg (83.78lbs)'. | 50 lb[source]Spec table: 'Net weight (lbs) 50 lbs' / '23kg'. |
| Warranty | 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. | 5 years[source]'5-Year warranty'. |
| List price | $1,699[source]Regular (strikethrough) price $1,699.00, sale price $1,499.00 (US$200 off), seen 2026-10-19, in stock.

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.
