≈ 0.9 days (24h/day) · Safe motor start buffer (75.9% margin).
chest freezer running (165 W max) and start-up (950 W max) draw fit the Bluetti AC180's 1,800 W continuous / 2,700 W surge ratings.
5–7 cu ft chest freezer with lid kept closed (~29% duty cycle, 23 W avg)
10–15 cu ft chest freezer at ~30% compressor duty cycle (33 W avg)
16–22 cu ft chest freezer or warm garage ambient (~32% duty cycle, 52 W avg)
≈ 0.9 days (24h/day)
System standby power: 15W (29.3% 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 5.7× starting surge (motor inrush) (75.9% worst-case surge margin).
Wall AC fast charge at up to 1440W (45m to 80%, 78m to 100%).
Safe envelope verified: Starting surge (650W) remains comfortably below the 2700W surge trip line, with steady-state operation settling into the safe continuous zone at 115W.
About 22.5 hours on AC power, with the chest freezer averaging 33 W (10–15 cu ft chest freezer at ~30% compressor duty cycle (33 W avg)). The Bluetti AC180 then draws about 51 W from its battery, including 15 W for the inverter itself. Best case: about 29 hours (5–7 cu ft chest freezer with lid kept closed (~29% duty cycle, 23 W avg)). Worst case: about 16.1 hours (16–22 cu ft chest freezer or warm garage ambient (~32% duty cycle, 52 W avg)).
Yes. The chest freezer's start-up peak of about 650 W (up to 950 W) fits within the Bluetti AC180's 2,700 W surge rating, with 65% headroom even in the worst case.
That simple division gives 35 hours, but the Bluetti AC180's inverter draws about 15 W whenever its AC outlets are on. At this light load that's 29% 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.
