System standby power: 15W (35.7% 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 6.7× starting surge (motor inrush) (85.2% worst-case surge margin).
Wall AC fast charge at up to 1440W (45m to 80%, 78m to 100%).
Safe envelope verified: Starting surge (400W) remains comfortably below the 2700W surge trip line, with steady-state operation settling into the safe continuous zone at 60W.
About 27 hours on AC power, with the mini-fridge averaging 25 W (3.2–4.4 cu ft double-door mini-fridge at standard 35% duty cycle (25 W avg)). The Bluetti AC180 then draws about 42 W from its battery, including 15 W for the inverter itself. Best case: about 35 hours (1.7 cu ft compact beverage cooler with thermostat set to 40°F (17 W avg)). Worst case: about 21.6 hours (4.5+ cu ft mini-fridge with small freezer compartment in warm ambient (35 W avg)).
Yes. The mini-fridge's start-up peak of about 400 W (up to 600 W) fits within the Bluetti AC180's 2,700 W surge rating, with 78% headroom even in the worst case.
That simple division gives 46 hours, but the Bluetti AC180's inverter draws about 15 W whenever its AC outlets are on. At this light load that's 36% 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.
