What it actually runs
Usable energy ≈ 979 Wh after our standard 85% inverter-efficiency assumption. Methodology
| CPAP overnightCPAP, humidifier off (40 W × 8 h) | ~24 h continuous · 3.1 days at typical daily use |
|---|---|
| EssentialsFridge + wifi + 3 lights (~190 W continuous) | ~5.2 h continuous · 0.6 days at typical daily use |
| Storm kitFridge + sump pump + lights + phones (~1,000 W) | ~1.0 h continuous · 0.2 days at typical daily use |

Solar recharge
The AC180 accepts up to 500 W of solar input — panels beyond that sit idle. To sustain an essentials load (~1,680 Wh/day) off-grid you'd need roughly 470 W of panels, within this unit’s cap — sun permitting, it can run essentials indefinitely.

Common questions
How long will the Bluetti AC180 run a refrigerator?
About 7 hours of compressor running time — which at a realistic duty cycle covers roughly 0.8 days of normal fridge use. Estimates use usable capacity (85% of rated) and carry ±15%.
Can the AC180 run a CPAP?
Yes — a 40 W CPAP runs about 3 full nights per charge without humidification. A heated humidifier roughly triples the draw and cuts nights to ~0.
Can it run a space heater?
Yes on output — a 1,500 W heater draws within this unit's 1,800 W rating — but only for ~0.7 hours. Resistive heat is the fastest way to drain any battery; an electric blanket (100 W) runs ~10 hours instead.
How fast does the AC180 recharge from solar?
At its 500 W input cap, roughly 2.9 hours of good sun for a full refill (real-world 80% derate applied). Cloud cover stretches that substantially.
