Answer
Can the BLUETTI AC180 run BLACK+DECKER BD12NWES 12,000 Btu/h window air conditioner?
Runs, surge risk
Runs, surge risk. Running draw 800 W is within 1,800 W continuous, but startup watts were not published. Willrun will not clear a compressor, pump, or tool start without that number. Estimated runtime: about 1.2 hr.

Questions
Can the BLUETTI AC180 run BLACK+DECKER BD12NWES 12,000 Btu/h window air conditioner?

What watts were compared?
Station continuous output is 1,800 W. No motor-surge rating is applied. Appliance running draw is 800 W.
How was the runtime calculated?
1,152 Wh × 0.85 = 979 Wh usable, divided by 800 W average draw.
Where did the numbers come from?
Spec table: 1,152 Wh, 4×120 V at 1,800 W, surge listed as 2,700 W, about 35.27 lb, LiFePO4, 3,500+ cycles. The FAQ defines Power Lifting as 2,700 W for heaters, hair dryers, kettles, and blankets, and says not to run an air conditioner or washing machine. Willrun therefore does not treat 2,700 W as motor-start capacity. ENERGY STAR lists 12,000 Btu/h, CEER 15, 115 V, variable-speed compressor, and 600 kWh/year. Rated input is 12,000 ÷ 15 = 800 W, which matches 600 kWh at 750 hours. Startup watts are not published.
