Last updated September 24, 2026. Manufacturer-spec comparison only—not a Boom lab test. Specs from BLUETTI’s AC180 US PDP and EcoFlow’s DELTA 2 page at ecoflow.com/us (note: EcoFlow’s Shopify us.ecoflow.com/products/delta-2-portable-power-station currently 301s to DELTA 3—use the DELTA 2 path below). Availability note: AC180’s US PDP shows discontinued / out-of-stock on the base SKU with a restock estimate on-page—confirm live stock. Real runtime depends on load, temperature, and inverter losses.
Two ~1 kWh LiFePO₄ mid-size stations with the same 1,800 W continuous AC headline. The real fork is printed base Wh, charge story, and whether capacity expands natively. Off Grid Power Boom keeps this manufacturer-doc only—no invented winner.
Quick decision
- Pick BLUETTI AC180 when you want the higher printed base capacity (1,152 Wh), 1,440 W turbo AC input (0–80% in ~45 minutes on BLUETTI marketing; ~1.3–1.8 h full on turbo table), 2,700 W Power Lifting / surge language, Bluetooth app, and wireless pad—accepting no native pack expansion (Power Bank Mode only).
- Pick EcoFlow DELTA 2 when you want 1,024 Wh LFP with native extra-battery expansion into the ~2–3 kWh class, X-Boost for higher resistive loads, ~500 W solar, and EcoFlow’s app / Always-On backup wording.

Decision table (manufacturer-stated)
| Spec | BLUETTI AC180 | EcoFlow DELTA 2 |
|---|---|---|
| Capacity | 1,152 Wh (AC180); AC180P variant 1,440 Wh on same PDP family | 1,024 Wh (also printed as 1 kWh on EcoFlow US) |
| Continuous AC | 1,800 W | 1,800 W |
| High-load / surge | Surge 2,700 W; Power Lifting Mode up to 2,700 W for heating-class loads (FAQ: not for AC / washer) | Surge 2,700 W on EcoFlow materials; X-Boost for higher loads (EcoFlow cites no-overload support into ~2,200 W class) |
| Cycles | LiFePO₄; 3,500+ to 80% | LiFePO₄; 3,000+ full cycles to 80%+ |
| Max solar | 500 W (VOC 12–60 V) | Up to ~500 W solar input on current US materials |
| AC charge highlight | Turbo up to 1,440 W; ~1.3–1.8 h full; marketing also cites 0–80% in ~45 min | 0–80% in ~50 minutes (X-Stream); ~80 minutes to 100% in EcoFlow lab graph note |
| Expandable | No native capacity expansion; B80/B230/B300 can charge it via Power Bank Mode + cable (FAQ) | Yes — DELTA 2 / Max extra-battery paths into ~2–3 kWh class |
| App / backup wording | Bluetooth app; pass-through charging Yes; no UPS/EPS label printed | EcoFlow app; AC Always-On / EPS-style switchover language on EcoFlow materials |
| USB-C | 1× 100 W Max | USB-C ports on EcoFlow port map (confirm live sheet for watt caps) |
| Weight | Tech Specs ~16 kg / 35.27 lb; another section on the same PDP says 37 lb / 17 kg—preserve the conflict | ~27 lb / 12 kg class on Boom’s prior EcoFlow-sourced table—confirm live sheet (marketing page stresses “portable & light” without always printing a single lb figure) |
| Warranty (pages) | 5 years | 5 years |

Who should buy / who should skip
Buy AC180 if…
- You find legitimate stock and want the higher printed Wh + turbo wall refill without buying an EcoFlow extra battery.
- Power Lifting for kettle / heater-class loads is on the checklist (respect BLUETTI’s appliance caveats).
Skip AC180 if…
- The PDP stays discontinued/OOS—shop current BLUETTI / EcoFlow mid-size SKUs instead of grey-market guesses.
- You need native pack stacking for multi-day outages—DELTA 2’s extra-battery path is the clearer printed story.
Buy DELTA 2 if…
- You want EcoFlow expansion + app ecosystem and 1,800 W in a ~1 kWh footprint.
Skip DELTA 2 if…
- A storefront redirect lands you on DELTA 3—different product; re-check the URL and model label (see also RIVER vs DELTA 2).
Failure modes
- Same watts, different Wh: 1,152 vs 1,024 Wh is a real but modest delta—do not round EcoFlow’s 1 kWh label into a fake precision fight.
- Expansion vocabulary: BLUETTI Power Bank Mode ≠ EcoFlow native extra-battery expansion.
- Shopify remap: EcoFlow product URLs sometimes 301 to newer models—buy the nameplate.
- Arizona heat: both LFP packs still need airflow; do not bury vents in a hot shed.
