How long will the BLUETTI AC180 run a refrigerator?

About 15.6 h for a median ENERGY STAR top-freezer fridge (363 kWh a year, 41.4 W average), 11.1 h for a bottom-freezer (566 kWh) and 10 h for a side-by-side (640 kWh). That uses 881.3 Wh of usable energy: 1,152 Wh × 90% usable × 85% efficiency, less 15 W of idle draw. Its output covers a modern fridge's compressor (160 W running, 320 W start-up) and defrost heater (425 W).

How many nights will the BLUETTI AC180 run a CPAP?

About 4.2 eight-hour nights for a ResMed AirSense 10 at 10 cmH2O with no humidifier (11.2 W, from ResMed's battery table), or 2.6 with the humidifier at 4 (27.6 W). Ask your equipment supplier before relying on a power station for a medical device.

How long does the BLUETTI AC180 take to charge?

BLUETTI lists 1.7 h from a wall outlet, 1.3 h in Turbo mode (app); car-socket charging isn't listed. Its solar input takes up to 500 W.

Can the BLUETTI AC180 run a sump pump?

It can start 1 of the 5 pumps we checked, allowing three times running watts to start. Zoeller M53, 3/10 HP: no; Zoeller M98, 1/2 HP: no; Superior Pump 92341, 1/3 HP: yes; Wayne CDU790, 1/3 HP: no; Wayne CDU980E, 3/4 HP: no.

How long will the BLUETTI AC180 run a fridge, CPAP or sump pump?

1,152 Wh, 1,800 W AC output, 2,700 W surge. After conversion losses about 881 Wh reaches your appliances. Every figure below is worked out from BLUETTI's published specs and the sourced appliance data on Methods.

Runtime for common appliances

Hours = 1,152 Wh × 90% usable × 85% efficiency ÷ (the appliance's watts + 15 W station idle draw), one appliance at a time, from full. Basis: BLUETTI EU AC180 article: DoD 90%, η 85%, self-consumption about 15 W. The output check compares the station's 1,800 W output with the appliance's peak running draw (a fridge's defrost heater counts) and its 2,700 W surge with the start-up draw.

CPAP nights

Medical equipment

A power station is not a medical backup system, and these are planning estimates. Ask your device maker or equipment supplier how to run your CPAP from battery power, and keep a plan for longer outages. What to check first.

Eight-hour nights at 10 cmH2O, through the AC outlet
AirSense setup	Draw, W	Nights
No humidifier, SlimLine tubing	11.2	4.2
Humidifier at 4, SlimLine tubing	27.6	2.6
Humidifier at 8, SlimLine tubing	43.9	1.9
Heated tube (ClimateLineAir at 30°C), no humidifier	18.2	3.3
Heated tube and humidifier, both on Auto	45.2	1.8
Heated tube at 30°C and humidifier at 8	59	1.5
AirSense 11, typical (ResMed user guide)	56.1	1.5

AirSense 10 draw is ResMed's battery-guide figure in amps at 12 V DC × 12 (ResMed battery guide). Nights = usable energy ÷ (draw + 15 W idle) ÷ 8 hours. Other pressures and machines: CPAP calculator.

Sump pumps

Start-up allows 3 × running watts, the top of Whirlpool's two-to-three-times range for motors. The example storm pace is 6 cycles an hour of 15 seconds each; time your own pump during rain.

Running watts are each pump's rated amps × volts, so they err high. Sump pump calculator.

Charge time and solar refill

Empty to full, from BLUETTI's published figures
Method	Time	Maker's figure
Wall outlet, standard	1.7 h	Standard mode about 1,000 W, 1.7 hours (1.7–2.2); Turbo about 1,440 W, 1.3 hours (1.3–1.8)
Wall outlet, fastest mode	1.3 h	Turbo mode (app)
Car's 12 V socket	not listed	Car input 12/24 V from a cigarette lighter port; watts not listed

"est." = worked out from input watts × 0.74 (wall) or 0.89 (car), the medians makers' own watts-and-time figures imply. See Methods.
