BLUETTI AC180 vs EcoFlow DELTA 2: Same 1.8 kW, Different Expansion Story

September 24, 2026

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.

Index

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.

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.
