Caveats
- BLUETTI's page said 'ships from November 20th' on 2026-11-05.
- No USB or 12 V ports without the $299 Hub D1; 84 lb, so it lives in one place.
- The 7,680 W Lifting Power figure is for resistive loads; a 1 HP well pump can draw about 7,200 W at start, which is marginal (generatorchecker.pages.dev well-pump test).
