≈ 1.5 days (8h/day) · Safe motor start buffer (94.8% margin).
box fan running (110 W max) and start-up (200 W max) draw fit the Bluetti AC180's 1,800 W continuous / 2,700 W surge ratings.
20-inch box fan running on low speed setting (50 W)
20-inch box fan running on medium speed setting (75 W)
High-velocity industrial air circulator on maximum speed (110 W)
≈ 1.5 days (8h/day)
System standby power: 15W (15.6% of total draw)
Provides 4× BS 1363 (230V) (120V 60Hz).
Pure sine wave inverter output. Safe for all standard household appliances.
Inductive motor/compressor load with 1.9× starting surge (motor inrush) (94.8% worst-case surge margin).
Wall AC fast charge at up to 1440W (45m to 80%, 78m to 100%).
Safe envelope verified: Starting surge (140W) remains comfortably below the 2700W surge trip line, with steady-state operation settling into the safe continuous zone at 75W.
About 12 hours on AC power, with the box fan averaging 75 W (20-inch box fan running on medium speed setting (75 W)). The Bluetti AC180 then draws about 96 W from its battery, including 15 W for the inverter itself. Best case: about 16.7 hours (20-inch box fan running on low speed setting (50 W)). Worst case: about 8.6 hours (High-velocity industrial air circulator on maximum speed (110 W)). At 8 hours a day, that's about 1.5 days.
Yes. The box fan's start-up peak of about 140 W (up to 200 W) fits within the Bluetti AC180's 2,700 W surge rating, with 93% headroom even in the worst case.
That simple division gives 15.4 hours, but the Bluetti AC180's inverter draws about 15 W whenever its AC outlets are on. At this light load that's 16% of everything the battery supplies, and inverter conversion losses take a further share. The idle figure comes from Bluetti.
On wall power: about 45 minutes to 80% and 78 minutes to full (Bluetti figures). With its maximum 500 W of solar input connected, expect about 400 W in full sun, so a full recharge takes roughly 3 hours of full sun, so it can refill in a single day with 4 peak sun hours.
