Specs side by side
| Spec | BLUETTI Elite 100 V2 | EcoFlow DELTA 3 Classic |
|---|---|---|
| Rated capacity | 1,024 Wh[source]Manual V5.1 spec table: 'Battery Capacity 1,024Wh (20Ah)'. The product page comparison table agrees. | 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) | 890 Wh[source]OutdoorGearLab measured '890 Wh out of its advertised 1,024 Wh' (87%). The test load is not stated. TechReviewer.de (apparently the 230 V EU unit) drew 946 Wh at a constant 500 W load and says usable capacity falls to about 80% at loads in the tens of watts. 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 continuous output | 1,800 W[source]Manual spec table: 'AC Output 1,800W Max., 120V, 15A Max., 50Hz / 60Hz'. Power Lifting mode runs resistive loads up to 2,700 W. | 1,800 W[source]'120V~60Hz 1800W total'. |
| AC surge output | 3,600 W[source]Official FAQ A4: '1,800W continuous AC output, 2,700W lifing power, and up to 3,600W surge with HyperVolt™'. The page meta description also says 'surge 3600W'. The US manual spec table gives no surge figure. | 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. |
| 240 V output | No[source]Manual spec table: 'AC Output 1,800W Max., 120V, 15A Max.' No 240 V output. | No[source]AC Output: '120V~60Hz 1800W total'; no 240V output listed. |
| Battery chemistry | LiFePO4[source]Manual spec table: 'Battery Type LiFePO4'. | LiFePO4[source]'LFP(LiFePO4)'. |
| Cycle life | 4,000+ cycles to 80% capacity[source]Product page comparison table: '4,000+ Cycles to 80% Original Capacity'. | Not publishedOfficial page gives no cycle count, only an estimated ~10-year lifespan from internal simulation. Retailer cycle figures (3000 or 4000) conflict and were not used. |
| AC charging | 1,200 W[source]Manual spec table: 'AC Charging 1,200W Max. (80% in 45 mins @25°C / 77°F)'; 'AC Input 1,800W Max. (Charging + Bypass)'; 'AC + DC Charging 1,200W Max.' | 1,400 W[source]'AC Input (Charge Only) 100-120V~15A 50/60Hz 1400W Max'. |
| Max solar input | 1,000 W[source]Manual spec table: 'DC Input 1,000W Max., 12V-60V, 20A Max.' Note that AC + DC charging together is still capped at 1,200 W. | 500 W[source] |
| Expandable | No[source]No expansion battery port. Official FAQ A18 says B80 batteries can be connected with an 'Aviation to XT60' cable, but only in the B80's 'Power Bank Mode', which charges the unit through its DC input rather than adding capacity. | Not publishedOfficial page does not state expandability. An independent review (thesolarlab.com) lists it as non-expandable. |
| UPS / EPS switchover | 10 ms[source]Manual spec table: 'Uninterruptible Power Supply (UPS) Switchover Time 10 ms'. The product page says '10ms UPS Backup' and the comparison table '≤10 ms'. | 10 ms[source] |
| Weight | 25.3 lb[source]Manual spec table: 'About 11.5kg (25.3lbs)'. The product page FAQ also says '25.3lbs(11.5kg )'; its comparison table rounds to '11.5kg (25lbs)'. | 26.7 lb[source]Official net weight '12.1kg+0.3kg', converted to lb (12.1 kg = 26.7 lb). |
| Warranty | 5 years[source]Official FAQ A7: 'it comes with a 5-year warranty'. | 5 years[source]3-year standard + 2-year extension only after EcoFlow app registration. |
| List price | $499[source]US$499.00 for the standalone unit, seen 2026-10-19. No compare-at price is shown (store data lists 499 as both price and list price), and it is in stock. A 'Bio-based' shell variant is shown at $499 against $699. | $599[source]Regular price $599; sale price $499 (pre-order) shown on 2026-10-18. |

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.
