Bluetti AC180

A standard CPAP without heated humidification draws about 35 W. The AC180's 1,152 Wh real-world capacity gives you roughly 26h 39m — comfortably more than one 8-hour night. With heated humidification on (around 80 W), drop that to about 11h 39m.

Yes. The 2,700 W surge rating clears the 1,000–1,200 W startup spike most refrigerator compressors hit, and the 1,800 W continuous output covers the 100–150 W steady-state draw. Realistic runtime on a typical 120 W fridge: 7h 46m. In practice fridges only run their compressor about 40% of the time when full and not opened often, so you'll usually see closer to 2× that number.

Phones (10 W): roughly 93 full charges. A laptop on continuous use at 65 W: about 14h 21m, or 3–4 full charge-and-go cycles. Tablets land between phones and laptops — most fully charge from about 15–25 Wh per session.

From a wall outlet (1,440 W max input): around 1 hour. From a 12 V car port: 8–12 hours (slow trickle). From a 500 W portable solar panel in good sun: roughly 4 hours of direct sunlight, which usually translates to one solid summer day or two cloudy ones.

The LiFePO4 cells inside the AC180 are rated for 3,000 full cycles before degrading to 80% capacity. Cycle it daily (heavy use) and that's around 8 years. For typical occasional use — say, 1–2 cycles a week for weekend trips and the occasional blackout — you're looking at 15+ years before noticeable capacity loss. The bigger limitation in practice is the inverter and BMS electronics, which usually go before the cells do.

Yes — up to 500 W via MC4 connector. Voltage range 12-60V. Compatible with most portable folding solar panels in the 100–500 W range; check that the panel's open-circuit voltage stays within the listed range. Our solar pairing calculator will tell you how long a specific panel takes to refill.

Yes. Switchover from grid to battery is 20 ms, well inside the tolerance window of every modern desktop, NAS, and home network device we know of. Plug your device into the AC outlet, then plug the power station's own AC input into the wall. The unit passes grid power through until it drops, then switches to battery.

5 years on battery and main unit, covering manufacturing defects and capacity degradation below the rated cycle count. Doesn't cover physical damage, water exposure, or unauthorized opening. Register the unit with Bluetti within 30 days of purchase to activate.
